Exhaust fans play a crucial role in maintaining proper ventilation, improving air quality, and preventing overheating in commercial establishments. These fans work by expelling hot air and bringing in cooler air from outside through intake sources such as open dock doors, windows, or static vents.

• Circulate air and prevent overheating: Commercial establishments such as factories, warehouses, and distribution centers can generate a lot of heat, which can be uncomfortable for employees. Installing commercial exhaust fans can help circulate the air, prevent overheating, and maintain a comfortable temperature for a more productive work environment. 
• Improve air quality: Indoor air quality is crucial for the health and comfort of everyone in the building. Industrial exhaust fans help to remove stale air, dust, and pollutants from the inside of the building and replace it with fresh air from outside. This controlled air exchange can reduce the risk of airborne diseases while also improving the overall air quality for your workforce. 
• Protect your product: Without a proper ventilation system in place, your warehouse can accumulate heat and humidity fast, which also subjects the items within storage facilities to the same harmful climate conditions. Protect your investment by properly ventilating the space to maintain a stable storage environment.

To find the correct fan you'll need, first take a look at your building and what it's used for. Storage? Operations? Or something else?

The number of desired air exchanges varies, but a general rule of thumb is: 

• 30 air exchanges: For buildings people are frequently inhabiting
• 20 air exhanges: For animal holding facilities
• 10 air exchanges: For storage buildings

Based on the values above, you can calculate the fan size you need by taking this formula:

(# of air changes per hour * volume of building in cubic feet)

And dividing your answer by 60 to calculate the CFM (cubic feet per minute) needed for your new exhaust fan.

Browse the Maxx Air collection above and choose the fan closest in CFM to your calculation, and don't forget about NFA! 

Net Free Air intake (NFA) for your exhaust fan must be provided through opening doors and windows, or by using static ventilation installed on the opposite side of the building from the exhaust fan in the form of gable and wall louvers, soffit vents, and other static vents.

Absolutely! All Maxx Air exhaust fans are compatible with the Maxx Air/Ventamatic thermostat model XXFIRESTAT, which is easy to wire-in and accomodates settings between 50° and 120° Fahrenheit to run your fan only when your set temperature is exceeded.
