1. Easy installation. Requires no wiring.


2. No operating costs. Imagine the savings.


3. Durable, galvanized, powder-coated steel housing.


4. Brushless DC 17V motor with resettable thermal overload protection.


5. Ribbed flange with rounded edge for strength and safety.


6. 20 Gauge steel housing & flashing stands up to high winds, hail, rain and snow.


7. Comes with 5~25 years manufacturer's warranty.


8.For manual control, we recommend our Control Box, complete with thermostat and ON/OFF switch, 

   sold separately.





What are the features of the attic fan thermal switch?

-----The thermal switch automatically turns the fan on when the attic temperature reaches 80 degrees 

and shuts off when the temperatures reaches 65 degrees. It also increases the life of the motor.

2. Does this solar attic fan have a battery backup?
-----No, all solar attic fans on the market today are powered by the solar panel directly to the motor. 

For additional run time, consider the solar attic fan controller, which turns the solar attic fan into a fan 

that can also use house power as a backup source.


3. How noisy is this attic fan? 
-----This attic fan is very quiet. We even put one in our own home and you can barely hear it, 

even when you are in the attic. 



Customer Feedback


My attic fan works,and didn't shut down once the sun went down,so if I wasn't home would still run all night.


I bought this because the price wasn't too
