How Can an Exhaust Fan Help in a Good Ventilation?

Improve ventilation in your property or place of business. If you’re looking to improve the flow of air inside, you need a good exhaust fan to take care of the job. Here’s how exhaust fans help air circulate, leading to proper ventilation.

Improve Air Quality

Air gets stale inside a property or building, especially when the windows are closed and there’s little to no air coming through. An exhaust fan can be used to change. With good brands like Canarm exhaust fan options, you can improve the quality of the indoor air.

Prevents Health Issues

With an exhaust fan to finally freshen up the air and make stale, musty air go away, you can prevent health problems. If your staff, customers, or tenants, you wouldn’t want stale air to lead to respiratory problems. If there’s a lot of dirt in the air, that could lead to asthma attacks. One way to prevent your staff or customers from getting sick is improving the quality of indoor air. That can keep asthma attacks and allergies at bay.

Enhance Overall Comfort

An exhaust fan that helps circulate air, leading to fresh, cooler air inside your home improves your overall comfort. Whether you’re cooking or showering, you can make sure the exhaust fan is working to keep the air clean and prevent the buildup of mold and mildew in the absence of good ventilation.

Prevents Mold

Mold and fungi thrive in places where there’s lots of humidity and moisture. If the weather took a turn for the worse and you’ve had more rain than usual, that could mean there’s plenty of moisture trapped inside your home. The lack of a proper ventilation system can lead to bigger problems. Getting a good exhaust fan is an easy way to resolve the problem.

Tips for Selecting the Right HVAC Exhaust Fan

There are several factors that you need to consider when you shop around for an exhaust fan. These suggestions will make it easier to navigate through the steps as you browse through online options.

Know What You Need

There are plenty of HVAC exhaust fan types around. That means you need to be clear about what you need before you can proceed. What you’ll require in an exhaust fan will determine the range of your options. Are you ventilating a building or kitchen? You’re getting the exhaust fan based on application, so start there.

Check Out Options

Now that you know what kind of exhaust fan you’re looking for start by checking out options. You can pick from three types. There are units mounted to the wall or ceilings, units designed for kitchen use, and units connected to the ductwork. That way, the fumes and stale air only go through the ductwork. It doesn’t affect the quality of any of the rooms.

Calculate Power Output

Make sure you pick the right size for your needs. If the exhaust fan is too small, it may not even generate much difference. It may not even work enough to be effective. That’s also why it’s considered standard to get an HVAC exhaust fan of about 75 CFM, even for those with a tiny bathroom.

Consider Sources

Shop online at reputable stores like Brooklyn Fan. With over a hundred years of combined excellence, the company is in an excellent position to provide for your needs. It offers a wide range of options, making it easier for you to shop without any worries. You won’t have to settle for a unit that doesn’t have the features or specs you need when you have so many options available. That improves your chances of finding the unit that’s perfect for your needs.

Understand the Features

Which ones are built for kitchen use? Which ones are perfect for smaller spaces? Find out what every option is built for. That will help you winnow down your options and find the exhaust fans that fit the bill.

Go Over the Buying Process

Is the ordering process easy? Can you send back returns? Does the company process returns with ease? Not all companies do that, so you’ll want to check on these details and sort them out. If the company makes it difficult for people to process returns, though, rethink your buying decision.

Industrial Fans: Direct Drive Blowers Or Belt-Driven Blowers?

Industrial fans are crucial components that should be included in an industrial manufacturing plant. These fans do more than improve efficiency and versatility in an industrial environment. Having the right type and number of fans in a factory helps you increase manufacturing capacity and maintain safe working conditions for employees. The big question is whether direct-drive or belt-driven blowers will do the work.

Belt-Driven Blower

The motor is fixed independently from the blades of the fan in a belt-driven blower. The motor is connected to the fan’s moving parts with one or more belts.


  • Speed control – A belt driven blower with varying sheave diameters allows you to control the fan’s speeds. Such flexibility is essential in material handling tasks where speed specifications may change over time.
  • Less wearing – The belts between the motor and fun absorb most of the wear and tear that could affect the fan and motor. This ensures the longevity of the system, unlike a direct drive blower.


  • High energy and maintenance costs – The friction between the two moving parts lead to higher energy and maintenance costs. These can be costly to the plant in the long run.

Direct Drive Blower

The direct-drive blower has a motor that directly controls the rotation of the blades. These blades are either connected to a shaft or axle. This fan, therefore, rotates at the same speed as the motor or less. However, it is essential to use a direct drive blower that rotates at the same speed as the motor.


  • Low maintenance – Direct drive blowers are built with simple designs that require fewer parts which means less maintenance. They only have a blower, motor, and coupling.
  • Tighter footprint – A direct-drive blower is compact and can seamlessly fit in tighter spaces with the wheel directly mounted on the motor shaft or coupled to the shaft.
  • Good for large applications – In blowers with over 200 horsepower, a direct drive is the best option. It promotes efficiency and motor longevity. This avoids the potential power loss resulting from belt tension pulls on the fan shaft in a lateral direction.


  • The direct-drive fan is less flexible than the belt-driven fan. This explains why it is also one of the expensive fan options when compared against the direct-drive fan.
  • Belt drive fans have a belt that acts as a noise reduction system. Direct drives tend to be louder because of the direct contact at the shaft.

Choosing Between a Direct Drive and Belt-Driven Blower

When choosing an industrial fan, you must consider energy efficiency, flexibility, and maintenance costs. Both blowers have their benefits and limitations, so it is better to choose based on objectives and industrial process specifications.

The Complete Guide to Commercial Roof Exhaust Fans Installation

Running a restaurant, café, or any business related to making food, one of the things you need is an exhaust fan. If you’ve already shopped for a model and you’re wondering how you’ll install that unit, here are fan installation techniques that you can try out.

Ducted or Ductless?

Before you get started on installing those commercial roof exhaust fans, is your kitchen ducted or ductless? Each option comes with different considerations, so you’ll need to get this right from the get-go. A mistake at this point can lead to mistakes that could compromise your unit’s operational ability.

Ductless Option

This is relatively easy since you won’t need to deal with the piping or ductwork. You’ll need to set aside an outlet for the exhaust fans, though, so if there are any problems or an overload, it will only affect one fan. That helps isolate the issue, making it easier to catch the problem and have pros fix it. To start the installation, figure out the center of the wall where the cooking range is, check the measurements of your new hood range, and then follow the instructions on the manual.

Ducted Option

This comes with a bit more challenge as you’ll need to have more knowledge of the system. It’s better to hire a professional to prevent any costly mistakes, as you’ll need to deal with the pipes, cutting through drywall, and using a drill or saw.

Clear the Clutter

Before the installation, clear out the clutter and furniture. Do this whether you’re going with a DIY approach, or hiring a pro. It’s easier to install the unit if there’s more than enough room for you or the crew to move around. The crew can move comfortably, too, if they aren’t worried that they might hit something.

Teach Your Team How

Make sure your staff knows how to operate the exhaust fans. You’ll need to tell them about common signs or indications that mean there’s a problem with the fans. That way, they can inform you if you need to call for professional repair assistance. The sooner the problem is fixed, the sooner your staff can work again in the kitchen without any problems.

Clean It Every Year

Routine maintenance and cleanup should be done at least once a year. Keep that in mind if you want to extend the service life of your unit. If you smoke a lot of food items, though, you might need to clean your exhaust fans much more frequently.

How to Maintain and Clean Canarm Exhaust Fans

Routine maintenance and cleanup of your exhaust fans are key to proper ventilation in your home. If you can’t remember the last time that you had those fans cleaned, though, here are tips to help you out.

Check the Manual

Before you get started, go over the instructions and suggestions from the manufacturer. What does the manual say? Read through the list before you attempt to start cleaning your Canarm exhaust fan.

Shut Off the Power

Once you’ve understood the steps, you’re now ready. Turn off the power from the circuit box to your fan first. This will prevent any accidents. You always need to make sure the power is off, so it’s safe for you to tinker with fan.

Check the Grate

Get a good look at the grate which covers your fan. Are there screws holding it in place? That means you’ve got an older model. You might want to think about getting a new exhaust fan if this is the case. Newer fan grates now use tension clips that are easy to remove. They also don’t require any tools. Whichever option you have, proceed by removing the grate.

Wash the Grate

If the fan hasn’t been cleaned in a while, the grate is probably dirty and dusty. Clean it with warm water and dish soap. It’ll be easier, though, to wipe away the dirt and dust first with a wet cloth before you wash the grate. It’s easier to clean it since you only need to throw out the wipe or wash the cloth. This prevents dirt and dust from going down your drain. That could lead to a drainage blockage, so you’ll want to prevent that problem.

Remove Dirt and Dust

Once you’re done with the grate, time to move on to the inside of the fan. You’ll need to remove as much of the dirt as possible. You can use a vacuum wand to make it easier to reach some of the nooks and crannies. You can also use a can of compressed air, though, that might lead to a mess in your home. You’ll want to do this out in the yard to keep the dust and debris out of your rooms. Use a dust rag to get rid of any other stubborn dirt that remains.

Replace the Grate

Once you’re done removing the buildup of dust and dirt, put the grate back. Be sure to remember to turn on your circuit breaker. Check if the fan works. And if it does, congratulate yourself for a job well done!

Things To Consider When Picking A Commercial Roof Exhaust Fan

Have you ever tried to hold your breath for a while? If yes, you know after a while it feels like your lungs might burst. It’s the same case for rooms; they need ventilation to get fresh air. It might be a manufacturing area, office, or even a restaurant. If no air goes in and out, moisture will increase, supporting the growth of mildew and molds. But what do you have to consider before buying an exhaust fan?

Determine the static pressure

Any flowing system encounters resistance. For instance, if your blood pressure increases, the blood flow in your body is hindered. So, when you think of airflow systems, it’s the system air resistance or static pressure. Before picking a roof exhaust fan, you need to measure the static pressure to overcome the resistance. When calculating, you need to consider factors like the length of the duct, the number of twists and turns they have, friction loss from filters, supply grille, and air washer.

Airflow demand of the room

Before picking a fan, you need to know the expected volume of air that will pass through your system. It will specify how much power your fan needs to deliver. It’s known as the airflow rate and is measured in cubic feet per minute (CFM). Knowing the airflow rate will help you pick the right one as all exhaust fans have a CFM rating. However, you should know that the airflow rate required depends on several factors. So, to be able to have the right rate, you can consult local building and safety codes for ventilation guidelines.

The noise level

All fans generate sound due to the spinning blades. The noise produced is known as the sone rating. So, before you pick a roof exhaust fan, you should check out the sone levels. In most cases, the sone level correlates with the CFM of the fan. So, always pick a balance between the fan’s power and how much noise you can handle. For example, in conference rooms where you need to hear people talk, the recommended sone levels are between 1.7 to 5. But for factories with heavy equipment, the sone level can go up and is 25 to 60

The energy efficiency

All ventilation fans must meet recommendations set by the US Environmental Protection Agency. For you to get an energy star rating, the roof exhaust fan must pass minimum efficacy levels, allowable noise, and performance. In addition, it will save you money from utility bills and reduce carbon due to its efficiency.

Picking the right exhaust fan can be challenging. However, if you have the right information to consider, you can never go wrong.

What Is the Difference Between Heavy Duty Exhaust Fans And Ceiling Air Ventilation Fans

Fans come in all types. They are available in different models and can fit in air ducts (inline fans) or hang from the ceiling (ceiling fans), while size and shape do differentiate them, what is a more determining factor in choosing a fan is purpose. This reduces fans to two types – exhaust and ventilation.

Exhaust Fans

Exhaust fans are removal specialists. They work to eliminate contaminants and other forms of pollutants from the air. In doing so, they prevent the inhaling of such harmful substances into the lungs and the possible medical problems arising from them. A heavy duty exhaust fan, for example, may be installed to remove the smoke from an industrial setting or a commercial kitchen.

Ventilation Fans

In contrast, a ventilation fan works to circulate air in a space. This could be commercial or residential. This type of fan draws fresh air inside from an outside source. A ventilation fan, for instance, suspended from the ceiling, spins in circles to circulate the air in a room.

Differences Between These Fans

A heavy duty exhaust fan and a ceiling fan are both intent on providing the air we all can safely breathe. The major difference between the two is purpose. The former acts to eliminate harmful substances floating in a space; the latter circulates the air present in a room, to refresh it.

If you have any questions about what type of fan you need, contact the dedicated and experienced staff of BF&B. We have a reputation for providing our customers with the most suitable fan for the task at hand.

Understanding the Energy Efficiency Codes Before Selecting an Inline Fan.

Energy efficiency and sustainability are no longer buzzwords in construction and manufacturing. They are now included in a wide array of codes enveloping all aspects of these businesses. If you plan on installing an inline fan, understanding the energy efficiency codes is now a priority.


Since 2010, the AMCA has published AMCA 205, Energy Efficiency Classification for Fans. Arguably, the most influential of the codes governing this sector, it has significantly affected this industry. The system is based not on the horsepower of a fan’s motor but on independent variables. It grants fans a FEG – Fan Efficiency Grade providing a standard for classifying fans in a range from minimal to optimal energy efficiency.


ASHRAE 90.1 is the standard for the minimum energy codes in buildings in the United States and globally for both design and construction. Since 2013, it has included a specific section referring to the energy efficiency of fans, including inline fans. It defines it according to the FEG in AMCA 205, Energy Efficiency Classification for Fans, of 67 or higher. The inclusion has impacted the decision of other associations in determining their standard and codes among other groups.


IgCC also has instituted a requirement for fan efficiency. It uses the FEG rating, setting the minimum rating at 71. However, it only applies to specific types of fans in structures smaller than 25,000 sq ft.

All the Different Things Industrial Fans Can Do for Your NY Factory

When you think industrial fans, might be thinking of Pennbarry fans or some other large venting fan company. Most industrial plant owners recognize Pennbarry fans, but they can rarely tell the next person how many different types of fans there are. If you need to replace any sort of industrial fan in your plant, become acquainted with the different types of industrial fans.

Energy Recovery Fans

Imagine if you could heat or cool your plant by using the existing air from outside. Doing so alleviates the massive energy bills an industrial plant tends to have each month. Energy recovery fans can act as a means of pulling air from inside and pushing it outside where the air is exchanged for air of a different temperature. This type of fan will keep your plant much more comfortable and use a lot less electricity to do it.

Industrial Ventilation

These enormous fans are used to pull particulates out of the air and make it safer for employees to breathe. They may be used over or in painting booths and above areas where there is a lot of dust accumulating. The particulates are removed from the air and stored in a filtered section in the fans until it can be cleared out.

General Ventilation

These are the fans used in other parts of your factory. They are made to circulate heated and cooled air for employee comfort. They also keep air circulating in break rooms and offices, computer rooms and meeting rooms, etc..
