Solar Direct Attic Fan

These 'whisper-quiet" solar-powered attic fans utilize an 11, 15, or 20 watt PV module to move up to 850, 1050, or 1250 cfm in full sun from your attic. The cover and base are paintable, molded, UV-stabilized, ABS plastic. The 5 bladed, 12" aluminum fan is pitched for maximum air flow and a stainless steel screen keeps critters out.

Each fan has a factory equipped thermal on-off switch. When attic temps exceed 80 degrees F, the fan turns on. When temps drop below 65 degrees F, it shuts off. If temps do not fall below 65 degrees overnight, the fan will start with the morning sun. The thermostat is simple to bypass in the field if desired.

The flat base of each model measures 24.5" x 24.5" and the overall fan height is 7". Each fan arrives fully assembled and typically installs in less than hour. The 1250 cools up to 2000 sqft.
