Are you considering purchasing inline duct fans? If so, then you probably already know some of the basic uses of these fans. However, you may not be aware of what inline duct fans are exactly or how they work.
Purchasing this type of fan is a great buy, and you should be aware of all the amazing benefits of doing so. For a guide on all you need to know about these fans and how they function, continue reading!
What Is an Inline Duct Fan?
These fans are cylindrical and will be installed in the place of one section of ductwork. So, in order for the inline duct fans to be installed, your HVAC ducting needs to be worked on and will be exposed. Depending on the type of unit, some easily plug in while others need hardwiring with a relay to the furnace that signals for it to kick on and off.
Because of this, in some instances, an electrician may be required for installation. Before making a purchase, know the shape and size of your ductwork. This ensures that you purchase the right unit size.
Once the installation is completed, these fans give you a quieter outcome than that of the register booster fans.
What Do These Fans Help?
Booster fans help circulate the air through the ductwork. They boost the airflow in a room, which increases how much warm and cold air makes it into a room. The inline duct fans do not rest on the ceiling.
They are attached to the ductwork inside the ceiling or attack and are located further away from the room.
What Are the Benefits of Inline Duct Fans?
Incline duct fans provide several benefits to those that choose them over standard booster fans. Some of those benefits are listed below.
Several Intake Points
Do you have a large bathroom? Are you trying to regulate heat in multiple rooms? This is where inline duct fans come in handy.
For largely sized bathrooms, you can opt to have two different intake points. With the use of a Y Junction, your inline duct fan can have multiple outlets or inlets.
Length of Duct Run
Because inline fans work with your ducting, they’re a much better option for connecting the extraction point to the outlet if these two points are far away from one another. For example, if you need to connect the fan from your bathroom to your roof vent, but the distance is quite far, a standard booster fan won’t be the best choice.
The inline duct fan’s ability to work with ducting also makes it useful for sub floor ventilation and heat transfers.
With standard booster fans, the minute they’re turned on, their noise is noticeable. They’re easily heard and can sometimes be quite annoying. But with inline duct fans, noise is no longer an issue.
Because they are located within the ducting inside the attic space, they aren’t close to the room that they are being used for. This significantly decreases the noise level of the fan. For those with well-insulated roofs, the noise will almost become non-existent.
If your roof’s insulation is not the best, there’s no need to worry. There are silent models available for purchase, which also eliminate the noise.
Unlike standard booster fans, inline duct fans come with the option of high power motors and in large sizes.
What Parts Are Needed?
Before an inline duct fan is installed, there are several parts that you’ll need prepared. Be sure to have all parts ready to go.
The external vent comes in the form of a wall vent or a mounted ceiling vent. There are plenty of options available so you’ll be able to find the right match for your room.
Know the size of the ducting that you’ll be using before purchasing the intake vent. The intake vent’s size will be dependent upon the size of the ducting. The intake vent is the extraction point of the system.
Intake vents come in a plethora of colors, shapes, and overall styles. You’ll have no problem finding one that suits your room’s decor.
Know the size of the ducting before purchasing the fan as well. It’s best to buy a fan that is the same size as your ducting. The fan is the main part of the system and not only will the type of fan depend on the duct sizing, but it will depend on the size of the room, the application, and other factors.
Your ducting should be as straight as possible for the best results. If you do not already have ductwork in place, you’ll need to have it installed with the fan. The ductwork connects the external vent to the motor and the motor to the vent.

The Inline Fan: The Bathroom Vent Fan You Need
An inline fan is an excellent replacement for an old and ineffective bathroom fan. It offers numerous benefits from installation down to its performance. But before we discuss its advantages, let’s look into the parts the make an inline fan system.
1. The Fan
This is the one you see spinning and exhausting the air from your bathroom outwards. The size of the fan depends on the size of your bathroom.
The fan’s performance lies on the diameter of your ductwork. Before buying a fan, you must first consider how your ductwork runs to the roof cap, the wall cap, or the soffit vent.
If you are targeting a powerful fan, you may need to replace your old wall cap.
2. The Interior Grille
The interior grille works as your bathroom ventilation exhaust point. There are many different grille types to choose from. But the bottom line is it should match your ductwork’s diameter.
Some grilles come with an integrated backdraft damper. This prevents outdoor air from coming inside your bathroom. Some grills also come with a set of louvers or a flap.
For top-notch performance, invest in a spring-loaded backdraft damper. Just make sure you get from reputable manufacturers.
3. The Exterior Vent
The exterior vent is where the air inside your bathroom passes through as it goes outside. Now you can position your vent in different areas. You can install it through your roof, your wall, or your soffit.
When it comes to ducting, keep it straight and short.
4. The Ductwork
The ductwork is where all of the other parts of the bathroom vent fan merge and work together. The goal is to connect the fan, the interior grille, and the exterior vent with your ductwork.
Now there are different kinds of ductwork available. Going for the insulated flexible ductwork requires less work. It also helps reduce the noise further.
There is also metal ductwork. This is more rigid compared to the first one. It also offers the least resistance to airflow.
Whether you choose the rigid or the flexible type, you must ensure that attic space has insulation. This will help protect your attic from problems caused by condensation.
Ductwork is one of the leading issues in residential ventilation design. Plan carefully and don’t rush when it comes to your ductwork.
5. The Switch
Lastly, your new inline bathroom vent fan needs a switch. Go for a switch that comes with a timer. This way, you will have no worries in case you forget to turn the fan off.
The Main Benefits
Now that you know the parts that make an inline vent fan work, let’s take a look at its main benefits.
1. More Power
You can mount an inline fan anywhere you want in your attic. Hence, space will not hinder its power.
You can also go for a large inline fan with a powerful motor. Generally, inline fans are way more powerful compared to your standard wall or ceiling-mounted fan. More power equates to topnotch efficiency in pushing moisture and expelling foul odors outside.
2. Minimal Noise
Since you don’t mount the fan directly against your ceiling, you can expect to hear minimal noise, at the very least. By installing the fan several feet away from the ceiling, you will not hear much of the noise coming from the fan vibrations.
Furthermore, your insulated ductwork also doubles as a sound dampener.
3. Different Exhaust Points
If you have a large bathroom at home, you can have multiple exhaust points for a single inline fan. All you need is a WYE connector that you will connect with your flexible ductwork. Of course, you also need to get additional grilles, depending on how many exhaust points you want.
Using the same concept, you can also extend your inline ventilation system to another bathroom. This equates to more savings since you don’t have to install a separate system for the other bathroom.
4. Longer-lasting Motors
Lastly, inline vent fans have motors that last longer. This means more years of service and fewer headaches when it comes to maintenance.
Before installing your new bathroom vent fan, take note of these important reminders:
- Make sure your fan exhausts the air outside of your house and not in your attic.
- Aim for smooth ductwork. Do your best to avoid bends and follow what the instructions say when it comes to the ductwork.
- Invest in a roof or wall cap that closes the vent whenever you turn off the fan.
- Ensure that your inline system moves the right amount of air per cubic feet per minute. This amount depends on the size of your bathroom.
- If you live in a place that really gets cold, stick to insulated ductwork. This will help keep condensation away from the duct.
- Check if the bathroom wiring you will use connects to a Ground Fault Circuit Interrupter.

Commercial exhaust fans. Air handler fans. Ventilation fans.
There are more industrial applications for fans than most people can even imagine. Where do you even start in order to learn the differences between types of fans?
That’s easy. We’ve got you covered.
There are two main types of industrial fans. Differentiating between the two is easy once you understand how each type of fan works and what its benefits and limitations are.
This guide will help you answer the question of “Centrifugal fan vs axial fan?” Read on find out the big differences between the two most popular types of industrial fans.
The first and oldest option for an industrial fan is an axial fan. Here’s all you need to know about it.
History of Axial Fans
Axial fans have been around forever. They’re the oldest design of a fan. These devices date back to the windmills designed by Persians in A.D. 500.
Engineers introduced the electrically powered fans to the public in the 1880s. These electric fans had the same design as the Persian windmills — an axial fan.
How an Axial Fan Works
An axial fan is called “axial” because it has blades that rotate around a fixed axis. The fan is named for the direction of the airflow that it creates as it moves air.
The blades that rotate around the axis pull air in parallel to the axis and force it out in the opposite direction — still parallel to the axis.
Imagine a ceiling fan. There’s one fixed point in the ceiling that the fan blades rotate around. The fan draws air down from the ceiling, parallel to the axis, and forced straight down to the floor.
The airflow remains parallel to the axis of the fan for the entirety of the flow.
Axial fans don’t require a lot of power input in order to run. They move air at a high flow rate, meaning that they can move a lot of air. However, the airflow is low pressure.
Best Uses of Axial Fans
Axial fans have a lot of uses, with most of them falling under the general purpose category. Consider one anytime you need to move a large volume of air from one place to another.
Low-pressure, high-volume flow is great for cooling spaces, such as a home or office building. It’s also great for cooling equipment, like the computer you’re using right now.
An axial fan is used in condenser cooling for a refrigeration system. It can also make a great exhaust fan.
As more technology is incorporated into everyday products, axial fans become more and more common. They are now used in vending machines to cool the computers that allow for cashless payment options.
For non-ducted applications, this model is likely the solution you need for airflow. Axial fans move a lot of air from place to place when working against little pressure.
The alternative option for an industrial fan is a centrifugal fan. Check out some quick facts on centrifugal fans to see if it’s right for you.
History of Centrifugal Fans
The centrifugal fan was invented in 1556 to ventilate mines. It disappeared from history after that. The design made a resurgence in the early 1800s.
How a Centrifugal Fan Works
Centrifugal fans are sometimes called blowers because they create a high-pressure stream of air.
A centrifugal can contains blades mounted around a circular hub. The motion of the hub pulls air in and around the hub, increasing the air pressure as it goes.
These devices move air radially. The end result is that the air coming in is “bent” at a 90-degree angle before it is pushed out the other side of the fan.
Although they function similarly, centrifugal cans are not the same as air blowers. The latter creates higher pressure ratios than a centrifugal fan can achieve.
This type of fan is typically attached to a system of ducts or tubes. This increases pressure, creating high-pressure airflow.
Centrifugal fans usually have lower flow rates, move lesser volumes of air, and have steadier flow than axial fans. They also require a high power input to operate.
Best Uses of Centrifugal Fans
Anytime you need to move air through ductwork, you will want to consider a centrifugal fan.
When ductwork is involved, the ducts increase pressure due to increased airflow resistance. To overcome this higher pressure, you need a fan that can produce high-pressure flow. You need a centrifugal fan.
This makes centrifugal fans ideal for air conditioning or drying systems. They are also great for caustic or corrosive environments. They’re extremely durable fans that work great for pollution filtration systems.
With enclosed parts and particulate reduction capabilities, these devices are difficult to damage and extremely durable.
Centrifugal Fan vs Axial Fan
Here are some of the key points you need to remember when choosing between the two types of industrial fans.
All things being equal, an axial fan:
- Has a higher dynamic pressure
- Has a higher operating speed
- Has a higher peripheral speed
- Requires less power for operation
- Moves a larger volume of air
- Is typically smaller, lighter and less expensive
- Creates low-pressure airflow
All things being equal, a centrifugal fan:
- Is more energy efficient
- Is more durable and resistant to harsh environments
- Is less likely to overload due to non-overloading horsepower curves
- Creates high-pressure airflow
- Moves a smaller volume of air
- Requires more power for operation
- Works better with ductwork
- Can be equipped with self-cleaning characteristics
Make an Informed Decision
So how do you choose centrifugal fan vs axial fan? It all comes down to the application. Depending on what you need it to do, where it needs to work, and how much air it needs to move, you can pretty easily figure out which type of industrial fan is the most appropriate choice for you.

While air quality isn’t something that’s often considered by workers, it’s one of the most powerful ways that workers suffer lasting health impacts. Breathing just a little bit of pollution day after day causes health issues that last for decades. On top of that, industrial ventilation ensures that your workers are comfortable and cool during the summer.
Here are five things to remember when you’re trying to keep your workers and the environment well ventilated.
1. Have An Expert Assess Things
When you’re trying to put together an HVAC system to handle your industrial ventilation needs, you should ask an expert. While you might be able to make a general assessment on your own, there are tools and tricks that professionals in the HVAC world know that you may not.
Make sure your warehouse can be separated into different zones if you have different temperature needs. This way you’ll ensure that you don’t have multiple blowers running nonstop at potentially conflicting temperatures.
An HVAC pro can take a quick assessment and tell you what your needs are for heating and cooling. If you have areas that stay unoccupied or is filled with automated systems, then they can set up heating cooling that makes sense. An expert will know how to make things optimal for equipment operation, product storage, or to keep your staff comfortable and productive all day long.
Setting up a series of temperature zones gives you more control and sets you up to have a more optimized temperature environment.
2. Have Smart Thermostats
As more elements of our daily lives are automated and controlled wirelessly, our heating and cooling needs are no exception. Having regulated warehouse temperature based on occupancy and activity is a great way to manage your heating and cooling needs. As you add more cubic space in your warehouse, your needs are going to expand.
If you don’t have to worry about the comfort of workers for 16 hours a day, you shouldn’t be heating and cooling for them during those hours. If you have programmable thermostats, you can automatically turn things off when no one is around. With interfaces built for smartphones and desktop devices, you can manage your temperature with the few taps or clicks.
You can set for complex needs, overtime work, or weekend adjustments as your workload changes. If you have products or materials with specialized temperature needs, you can change things temporarily until those items are moved or shipped to a new location.
3. Occupancy Sensors Save Cash
As mentioned above, occupancy plays a big role when you’re worried about the temperature of your warehouse or space. Occupancy sensors solve a lot of the common issues that companies face when trying to heat and cool their space. Turning off the lights or the HVAC system as people leave the space could end up saving a lot of money over time.
Fluorescent or LED lighting is ideal for these kinds of sensors. Since you’ll need a fast response and quick start-up to keep from delaying the work that your staffers want to do, avoid metal halides.
Sensors like this should be connected with temperature control since most light emits heat.
You’ll save potentially thousands a year when you’re able to keep the lights off as you don’t need them. Turning off lights that you don’t need ensures that you’ll be able to lower your carbon footprint as well.
LED lighting can be harsh, so make sure you get multiple lighting to mix frequencies. LED is typically one frequency and long exposure to those lights causes some people to have headaches. Try a few schemes out to see hat your staff prefers before you commit to one.
4. Use Earth Science To Your Benefit
As most people learned in school, heat rises. That means your hot air is going to go to the ceiling as soon as it leaves the ground floor. If you have hot air in your warehouse, then you should push it back down during cooler months and suck it out during warmer months.
When it comes to temperature control, hot air near your thermostat is going to change how your HVAC system responds. If you put your thermostat next to your hottest piece of equipment, it’s going to impact your temperature. You’ll always be a little off if you place it in the wrong spot.
Ceiling and exhaust fans can help you manage and disperse your air evenly. Recirculating air helps to smooth and even out the temperature of your warehouse. If you’re able to keep the air moving around, you’ll be able to save money because your temperature will reflect the actual feeling in the space.
5. Rooftop Units Need To Be Checked
While most warehouses put their HVAC units on their rooftops, there are a whole host of problems that come with that. The place where your HVAC system is going to be under the most amount of stress.
If your unit is out there on a hot summer day, made out of metal, and painted a dark color, it’s going to be under stress. On top of that, if there is a dusty factory nearby or a storm that blows debris into it, your HVAC unit is going to work to kick that dust out.
All year round, your rooftop units are going to struggle to stay clear of debris and running smoothly. Make sure you have it inspected by a professional regularly to keep the ventilation ducts clear and your staff happy.
Industrial Ventilation Improves Productivity
When you have goo industrial ventilation, you’re able to keep your workers happy and healthy. You also keep products and materials free of problems that come with pollution and impurities.
If you have a kitchen or food production facility, check out our guide for ventilating that specific space.
Kitchen exhaust fans have one of the most important jobs in your commercial kitchen. These mechanical fans keep your kitchen air clean, reducing greasy buildup around the area and maintaining employee comfort.
Keeping exhaust fans in top shape is essential to a well-maintained kitchen area. Because they’re working to remove and filter air, these fans require regular cleaning and maintenance.
This equipment works hard in the background and is easily forgotten. Regular maintenance is a must, however. To learn more about keeping up exhaust fans for kitchens the right way, read on.
What Are Kitchen Exhaust Fans?
Kitchen exhaust fans, also known as range hoods, have the heavy duty job of removing impurities and moisture from the air in a commercial kitchen. These fans are situated directly above stove tops and cooking surfaces. They consist of a hood (also called a canopy) and a fan.
The hood serves to capture dirty, moist air. Meanwhile, the fan inside extracts this air and moves it away from the kitchen and outside. In a kitchen setting where cooking is constant, this action removes:
- Steam from boiling water and simmering foods
- Strong cooking odors
- Grease particles
- Harmful vapors and pollutants
- Excess heat, which is especially helpful in warmer months
Removing air pollutants, steam and heat makes it easier to cook in the kitchen. Adequate ventilation in a busy commercial kitchen is made possible by hard-working fans. A comfortable cooking environment is necessary for optimal productivity.
Removing grease particles and humidity from the air is critical to maintaining a clean environment and properly functioning equipment. Thick, sticky grease buildup is difficult to clean when it settles on and clings to other pieces of equipment. It can block airflow in other appliances and make the kitchen look unsanitary.
In addition to being dirty and unsightly, grease buildup increases the chances of a grease fire in the kitchen. Its removal could prevent a serious health hazard.
Excessive moisture can also be very damaging in a commercial environment. Without exhaust fans, humidity would condense and collect on walls, furniture, and equipment. In time, this can lead to noticeable water damage in vulnerable areas.
Well-maintained commercial exhaust fans prevent grease and moisture from becoming issues. They do far more than just remove odor. They prevent costly damage.
Working in a kitchen can be miserable when the thermostat keeps climbing. Kitchen fan venting pulls extra heat away from the cooking area so that employees can stay cool. This can also help keep air conditioning costs down as it prevents heat from collecting.
Maintaining Kitchen Exhaust Fans
To properly vent and filter the air, kitchen exhaust fans must be maintained on a regular basis. Their efficiency and lifespan depend on it.
Since commercial fan setups are heftier than home units, you’ll need to follow a few extra steps when tackling this job.
Unplug the Exhaust Fan Unit
Commercial appliances must be unplugged before maintenance to avoid injury or death by electrocution. These are big units and will require a lot of cleaning solution.
It’s also a good idea to use a tarp or painter’s drop cloth around the area while you’re cleaning to catch drips. No cooking should be done while unit maintenance is in progress.
Remove Grease Containment Traps
Most commercial kitchen exhaust fans have grease collecting receptacles on the side of the hood. This grease can be put into sealed metal containers for proper disposal at a later time.
Soak the grease traps in a mixture of very hot water and grease-cutting cleaner. This will soften the sticky residue so it can be removed.
Remove the Filters
Kitchen exhaust fans have filters for catching grease, dust, and other particulates. Like the grease traps, these kitchen exhaust fan filters quickly become coated with thick greasy residue and can lose their effectiveness when not cleaned regularly.
When cleaning your traps, remove these filters. They should be soaked in the same hot water solution as the traps so the grease can be loosened. After soaking, they can be scrubbed with a nylon brush to remove remaining residue.
Under the Hood: Cleaning the Hood and Fan
The kitchen exhaust fan cover, or hood, will need thorough cleaning just like the rest of the unit. While your traps and filters are soaking, make a similar cleaning solution for your hood. These solutions should always consist of an approved grease-cutting cleaner and hot water.
Both the interior and the exterior of the kitchen exhaust hood need to be scrubbed with a soft cloth soaked in the cleaning solution. All surfaces and corners should be addressed to avoid gunk and grease collection that can lead to fire hazards.
Cleaning the Fan Blades
The fan blades of your kitchen exhaust unit will need to be carefully cleaned as well. All of the dirty air that is removed from your cooking area passes over these blades. The filters do a good job catching the bulk of the particles, but they can’t filter everything.
When cleaning the fan blades and the hood of your kitchen exhaust fans, never spray cleaning solution directly into the unit. You should avoid directly wetting any of the electrical components during the maintenance process. To avoid unintentional wetness in the unit, always use a cloth that has been dipped in the solution to scrub instead of directly spraying cleaner into dirty areas.
When all of the components of your unit are clean and dry, reassembly is in order. You’ll need to reinsert filters and traps before plugging the unit back in.
Regular Maintenance for Top Performance
Exhaust fans work hard to remove the junk from the air in your commercial kitchen. Maintaining a regular cleaning schedule for your kitchen exhaust fans will ensure that your kitchen stays cleaner, safer, and more comfortable.

How much time do you spend in your bathroom a day? It’s an area of the house that might not be the most glamorous, but it’s still important.
That’s why, on average, we spend between $5000 and $21,000 on bathroom renovations. Keeping our bathrooms as fresh as we keep ourselves can help keep these costs down.
Keeping your bathroom fresh isn’t always as easy as opening a window, however. You’ve got to consider everything from air humidity to water damage.
That’s why having the right bathroom ventilation is so important. Here’s our guide to ventilation for your bathroom to help you realize just why you need it.
The Purpose of Bathroom Ventilation
Before you purchase a bathroom vent fan, you should understand the purposes behind buying and installing one.
The main reason people install a bathroom vent is to tackle moisture and odors. Bathrooms, especially if you have a shower or bath, are the perfect ground for moisture to build up in the air.
If there’s not enough air circulation, the humidity of your bathroom will stay high, as will the heat, creating a haven for mold and other toxins.
That’ll also cause your bathroom to start to smell as the damage to your fixtures and fittings spreads.
That’s why you need a bathroom ventilation fan. Circulating the air can cool it down, remove moisture, and limit the damage.
Types of Ventilation Available
There are several types of ventilation available for your bathroom.
The most common type of ventilation fans available are those that are mounted on the ceiling. Remembering your basic physics, hot air will rise, making a ceiling fan the best option to help remove damp and warm air after a hot shower or bath.
You can also have fans that mounted into the walls. These will suck the warm air outside, much as a ceiling fan would. You can also have inline fans which can be ceiling or wall mounted.
The size of the bathroom vent fan you need will vary, depending on the room size. You can help choose the right sized ventilation fan from this sizing guide.
Benefits of Bathroom Vents
We’ve briefly touched upon the benefits of installing a bathroom vent, but it’s important to understand that it’s not just about air circulation.
Vents in your bathroom can help you save money. You’re not going to be spending as much on bathroom renovations if your bathroom stays in better condition over a longer period.
Removing moist air can keep your fittings, fixtures, walls, and decor in better shape.
You also won’t have to worry so much about your health. With no mold spores in the air, you won’t have to worry about the quality of the air you’re breathing in, thanks to the ventilation you install.
And yes – your friends and family will thank you for it. You won’t have to worry about any kind of lingering odors in your bathroom, due to mold or anything else, because your vent fan will remove them for you.
Before you purchase a fan, there are several other things to consider, such as installation costs, noise and fan quality.
Depending on the contractor you choose, the installation of a bathroom fan could cost you several hundred dollars in parts and labor. You can reduce some of the costs by completing some of the labor yourself.
Here’s our helpful guide on how to install a wall exhaust fan yourself.
You need to be aware of the fan capacity. The fan you purchase will have a performance measurement of air removal by cubic feet per minute (or CFM).
The greater this number, the more air that can be removed, although you don’t want to overdo it.
As we’ve mentioned previously, you need an appropriately sized fan for the size of your room. According to the Home Ventilating Institute, a good figure to work with is one CFM per square foot of the area of your bathroom.
You should also consider the fan’s sound rating to determine whether it would be suitable for use in your own bathroom.
Do You Need Vents for Your Bathroom?
Is ventilation for your bathroom really necessary?
That’s your decision to make, but we believe so. Ultimately, the purpose behind purchasing a bathroom vent is for better air circulation and better air quality.
Your bathroom is the ideal area for hot, warm and wet air to collect.
You might think you can get away without one if you have a window, but a window doesn’t have a fan, so you aren’t getting the best circulation you need to replace the air.
And if you don’t have a window in your bathroom?
Then you definitely need a vent. Mold, once it’s in place, is hard to shift. It can build up in areas all over your bathroom, inside your walls, and cause you to be seriously ill.
Why put your health at risk?
Don’t Neglect Ventilation in Your Bathroom
Without adequate ventilation, you’re causing damage – to your health, to your bathroom, and to your wallet.
Ventilation can help remove harmful bacteria that might be lingering in the air. It can also limit the damage that high humidity can bring, such as mold.
You also won’t have to worry as much about bathroom decor and maintenance.
Do you have questions about bathroom ventilation that need answering?
Don’t be afraid to get in touch so we can help you find the right ventilation system for your bathroom.
Try holding your breath for any amount of time. You’ll start feeling like your lungs are going to burst after thirty seconds.
A room needs to breathe like our bodies. Whether it’s a restaurant, a manufacturing area, or an office, they’ll all need adequate ventilation. Bad air has to get out to let fresh air in.
Otherwise, the room will suffer just like your lungs did. You can’t ignore unwanted odors, but they are probably the least of your problems. Moisture levels will increase and that will lead to molds, mildew, and other nasty stuff.
Choosing the best exhaust fan for your needs guarantees that your facility can breathe easy. How do you know if you’re buying the correct one? Here’s what our experts say.
Consider the Airflow Demand of the Room
Calculating the desired volume of air that goes through your ventilation system will determine how much power your fan will need to deliver. This is the airflow rate and it’s expressed as cubic feet per minute (CFM). All exhaust fans will have a cfm rating.
The rate of airflow required depends on several factors. You can consult your local building and safety codes for ventilation regulations.
Occupancy and Area
For commercial buildings, cfm rates vary by type of occupancy. You can have a rate per unit area and a rate per person taking up space.
These are numbers from ASHRAE (American Society of Heating, Refrigerating, and Air-conditioning Engineers Inc) Standard 62.1-2010 commercial building code provisions for indoor air quality: a classroom (with children age 5 and up) will need 10 cfm per person and an additional 0.12 cfm per square-foot.
An office requires 5 cfm per person and an extra 0.06 cfm for every square-foot. ASHRAE also provided a default value of 17 cfm per person in the office. They used the default occupant density of 5 persons in a 1000 square-feet area to come up with that value.
Some spaces have a variable number of occupants at any given time. Assembly halls, gymnasiums, and theaters are some examples. The air change method of calculating the cfm is more useful in these situations.
For the air change method, you need the following data. First is the total cubic feet of airspace. You can calculate this by multiplying the dimensions (length, width, and height) of the room.
The second number is the minutes per change (min/chg). This is the amount of time in minutes that one cycle of air goes through the room and ventilation system.
To get the cfm, you divide the total airspace by the minutes per change. For example, a theater has a suggested min/chg of 2 to 10.
You’d want the lower number of min/chg if you want the air to change quickly. For spaces with low ceilings, in hot climates, or with heavy occupancy relative to the size, use the lower number.
You can use the higher range for comfort cooling.
If the temperature inside a structure is higher than the outside air temperature, your ventilation system can provide some degree of cooling. To illustrate this principle but on a smaller scale, look at your desktop pc. The pc chassis has fans installed with intake and exhaust for optimal airflow and cooling.
To calculate the cfm using the heat removal method, you’re gonna need some numbers. First is the amount of heat to remove in BTU (British thermal unit) per hour. Next are the average outdoor temperature and the desired indoor temperature.
The formula is CFM = BTU/(Delta T x 1.08) where Delta T is the difference between the outdoor and indoor temperature.
Determine the Static Pressure
All flowing systems encounter resistance. For example, the flow of blood through your body is hindered by an increase in blood pressure. For airflow systems, this is the static pressure or system air resistance.
Figuring out the static pressure is important because your exhaust fan has to overcome this resistance for sufficient airflow. The traditional measurement for static pressure is in inches of water.
There are a lot of factors that contribute to an increase in static pressure. You have to add them all up to calculate the total external static pressure.
One of the biggest contributors to static pressure is the length of the ducts and how many twists and turns they have. Other factors are friction loss from filters, supply grille, and air washer.
Where Will the Fan Be Installed?
There are three places where commercial exhaust fans are commonly installed. These are the rooftop, the wall, or in the duct. Some laws require you to install the exhaust fan at a specific location. If you’re working with chemicals or flammable substances, a roof exhaust fan may be the best option.
Where the fan will get mounted will also decide the fan housing and accessories, such as wall caps, vents, and shutters.
Acceptable Noise Level
The spinning blades of a fan will always generate sound. The noise level is the sone rating. You should check out the sone levels of the exhaust fan model before purchase.
The sone levels correlate with the cfm of the fan. You should, therefore, pick a balance between how powerful the fan is and how much noise you can tolerate.
For conference rooms, where you need to hear people talking, the suggested sone levels are between 1.7 to 5. For factories operating heavy machinery, sone levels can be as high as 25 to 60.
The Best Exhaust Fan Must Be Energy Efficient
You need ventilation fans to meet the guidelines set by the US Environmental Protection Agency. To earn an energy star rating, the exhaust fan must pass minimum efficacy levels, performance, and allowable noise.
An energy efficient fan will save you money from utility bills. Also, you should feel good that you’re reducing your carbon footprint by choosing an energy efficient product.
Taking It All In
You have to research and be diligent to choose the best exhaust fan for your needs. While all this data may be intimidating at first, we hope that understanding what they mean will help you make the correct purchase.
When you’re trying to improve ventilation in your commercial space, sometimes it can be difficult to know where to start.
You’ll need to think about your air pressure, the quality of the air in your space, and even where you’d like for the air to go.
You’ve read about the benefits of a centrifugal fan, and you’re ready to learn more about what they can do.
In this post, we’ll tell you everything that you need to know about centrifugal blower fans.
From how they work to what makes them the best choice for your commercial space, read on to get your questions answered.
What Is a Centrifugal Fan?
Before we get into the benefits of having a centrifugal fan, let’s first make sure you’re clear on what it is.
Also known as centrifugal blowers, these fans help to move air and gases in industrial and even larger commercial spaces.
It’s made of up a fan blade, a motor, and an enclosure surrounding it — though the motor size and the fan blade shape can vary according to the specifics of the design.
You’re also able to select the direction in which the blades of the fan rotate.
Essentially, these blower fans work by creating low pressure in the blade’s center, which vacuums the air into the fan. The edges of the blade are areas of high pressure, and they also work to push out kinetic energy.
That air is then pushed outside of the fan’s enclosure.
Their strength and power make them especially helpful in air pollution control, ventilation in an area where a pressure drop is present, and chemical processing units, among other things.
These expert air blower options also help with dust collection, keeping air clean thanks to their drawing power.
They’re also used in agricultural settings to help with controlling the overall temperature of the air. They can quickly dry farming chemicals, grains, and much more.
Many businesses rely on centrifugal fans because they can work with a wide variety of different materials. They can stand up to sawdust, wood chips, scraps of metal, and even alloys.
Finally, the ability to customize these fans to the specific needs of your space also makes them a popular option.
Now, let’s take a closer look at the benefits of these blower fans.
They’re Low Maintenance
One of the best things about a centrifugal air blower is how low maintenance it is.
Especially if you already have to spend thousands of dollars per year having your larger pieces of equipment inspected and maintained, you want to save on operating costs where you can.
So, while period cleaning is important, as too much dirt and dust accumulating on the blades can lead to overheating and early motor failure?
You’ll find you don’t have to clean them as often as you might think. You can even use a small vacuum to clean the motor surface and ventilation openings.
In some cases, you may even be able to find blower fans that have self-cleaning features. This will make your job all the easier.
They’re Energy Efficient
Just like your cleaning and maintenance bills, we know that you’re also looking for ways to keep your energy bills under control.
A centrifugal fan can certainly help with that.
This is all thanks to their constant airflow, which keeps energy efficiency levels high.
They Can Handle Different Airflows
Whether you need a fan for a commercial building or an industrial factory, one thing is clear: they need to be able to handle different airflows and pressure.
Centrifugal fans can stand up to almost any challenge you put in front of them. They can process clean air, dirty air, and even wet air.
When you make an investment in any kind of equipment for your business, you want to be certain that it can stand the test of time.
Centrifugal fans certainly can, thanks to their high levels of durability.
Even if you need to put the fans in an environment where they’ll need to deal with corrosive elements, they’ll still be able to work well.
They Can Prevent Overloading
The last thing you want to have to deal with is a fan whose motor frequently shuts off without warning.
Not only is an overloaded fan potentially dangerous, but it can also seriously slow down your workflow and shorten the fan’s overall lifespan.
Luckily, you can shop for a centrifugal fan that comes with horsepower curves. This will prevent the motor from overloading and shutting down if conditions suddenly change or if it reaches maximum capacity.
Last but not least, the popularity of centrifugal fans is due in no small part to the ability you have to customize it.
These fans come in lots of different sizes so that they can help in all sorts of spaces within your building.
