QuietCool Attic Fans work almost everywhere, almost anytime. During the summer, an
attic can be 40-50 degrees hotter than the outside temperature, which in turn heats up the
house very quickly. With an attic fan, you can cool the attic to the same temperature as it is
outside, greatly reducing the house from heating as quickly.
With the QuietCool Smart Attic Fan, gone are the days of having to adjust the thermostat
for your attic fan. Featuring a built-in thermostat and humidistat, the self-adjusting,
10-speed ECM motor is always reading the temperature and humidity in the attic.
When the fan detects temperature over 80 degrees, or humidity over 60%, the Smart
Attic Fan comes on at the lowest speed. As the attic starts to heat up, the Smart Attic Fan
automatically adjusts it’s speed.

With the QuietCool Smart Attic Fan, the attic can stay cooler than it otherwise could with
a traditional single-speed attic fan, and will help save you energy by running the fan at a
lower speed (thus a lower wattage) when the attic is not as hot.
