Use this Smart Attic fan to keep your attic cooler, without any complicated wiring or setting adjustments. The QuietCool Smart Attic fan is the first attic fan with a built-in thermostat and humidistat. The self-adjusting, 10-speed ECM motor is always sensing the temperature and humidity in the attic to adjust itself depending on the conditions in the attic.
When the fan detects a temperature of over 80 degrees or humidity over 60%, the Smart Attic Fan comes on at the lowest speed. During the day, as the attic starts to heat up, the Smart Attic Fan automatically adjusts it’s speed.
The QuietCool Smart Attic Fan moves 2,830 CFM on the highest speed at only 145 watts! At the lowest speed, the fan moves 963 CFM at just 15 watts.
This attic fan helps keep your attic cooler than a traditional single-speed attic fan and helps save you money by running the fan at a lower speed (therefore using a lower wattage - and saving electricity).
