Warehouse Ventilation 101

If you own a business or a retail company, at some point, you will most likely need to utilize a warehouse to store your products. Whether 3,000 square feet or 300,000 square feet, warehouses all have one thing in common…they need to be well ventilated. A poorly ventilated storage space can destroy all of your product—and your profits!

If your storage space is damp, mold can grow and metal products or parts can rust. If there are any chemicals in your products, the air can become contaminated and dangerous to humans. If your storage space is hot, products can melt or dry out. Without warehouse fans, it’s not a warehouse, it’s just a building.

If you want a well-ventilated warehouse, you need to use warehouse fans. Whether you need to dry, cool or de-fumigate a space, an exhaust fan is the way to go. Three questions to ask yourself before purchasing your warehouse fan: What is the volume, what is the purpose and what is the climate of the area you need to ventilate?

Terminology for Your Technology

A term used to refer to volume of air that a unit can move is “cubic feet per minute,” or CFTM. When you know the volume of the area you need to ventilate, calculate the cubic feet of space in that area. Then check the CFTM number on the fans you are looking to buy and determine how many are needed to ventilate your space.

Another term you should be familiar with is “water gauge,” or WG. This is a rating of the level of resistance air presents as it flows through a fan, such as with air heavy with water vapor or airborne particles.

What’s the Difference?

There are two types of industrial fans typically used in warehouses: the centrifugal fan and the axial fan. A centrifugal fan blows air out by using deflection and centrifugal force. The air exits the fan at a right angle. These are generally more powerful than axial fans but are also noisier. An axial fan moves air through propeller-type blades that rotate around an axis. The air flows in a linear path. Axial fans are less expensive and quieter than centrifugal fans, although they do not move the same volume of air. A very common type of axial warehouse fan is the large ceiling fan, also known as an HVLS—or “high volume, low speed” fan. This inexpensive option draws air up and mixes the cooler air from the lower space with the warmer air of the upper space and results in an overall cooling effect.

Whether you’re new to “Fandom” or if you’re seasoned pro, proper ventilation will keep you and your goods cool and dry.
