How Attic Fans Work

Sizing

We recommend sizing your attic fan at .5 CFM per square foot of attic space for every 2 feet of peak attic height. This formula gives a minimum of 15 complete air exchanges per hour.

This means for a 1500 SQFT attic with a peak attic height of 4 feet, you will need an attic fan that moves at least 1500 CFM. If the peak attic height is only 2 feet, you would need at least 750 CFM. If the peak attic height is 6 feet, you would need at least 2250 CFM, and so on.

Solar Attic Fans VS. Smart Attic Fans

The key difference between a smart attic fan and a solar attic fan is the ability to easily control the fan’s operation from the convenience of your smartphone. Adjusting the fan’s speed, turning it on or off, and monitoring the temperature and humidity levels in your attic is a breeze with the custom seasonal presets available.

Smart Technology Explained

The QuietCool Smart Control app offers the ability to see the attic temperature and humidity levels, manually run the fan, enable smart mode for automatic cooling and ventilation, adjust settings and presets, and more.
