Application:

 

 

 

Advantages:

 

A solar fan is more environmentally friendly.

 

Though initially the installation may be costlier, in the long term it would turn out to be cheaper.

because it does not use power from the utility grid 

and may provide savings up to 30 percent on air conditioning costs.

 

Risk of electric accidents are eliminated as there are no electric cords attached to the solar fan.

Another great benefit of having a cordless appliance is that 

it has much more mobility compared to conventional fans.

 

 
 
FAQ:

1. 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. Can I install this attic fan on my flat roof?

------ It is not recommended because you would need to build a curb for it.

3. 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.
