This Solar Fan automatically regulates itself.  When the sun is low in the morning, the fan runs slowly.  
As the Sun gets higher in the sky, your fan will automatically speed up to dissipate the extra heat.  
So, during the hottest part of the day, your fan is running at its fastest speed.  
And at night, it automatically shuts off.  In addition, we include an 85 degree thermostat already installed!  
It will turn on the fan anytime your attic is above 85 degrees and there is sun shining.  
This greatly increases the life of the unit because it will not run when it is not needed.

  • Black solar panel for improved camouflaging on most roofs
  • Ventilates up to 2000 feet of attic space with a single fan
  • Brushless DC 17V motor with resettable thermal overload protection.

  • Intelligent temperature control without manual operation. It starts working when temperature is above 25 ° C and stops below  23 ° C.

  • Ribbed flange with rounded edge for strength and safety.
  • Sealed shell design. Anti-UV material is added in the outside shell. Perfect weather fastness, durable.

A. Easy installation. Requires no wiring. No operating costs. Imagine the savings.
B. Multiple protective devices, waterproof, insect prevention, rat proof and sundries proof
C. Durable, galvanized, powder-coated steel housing.
D. High Efficiency long life brushless motor starts in lower light  and overcast conditions.
E. Ribbed flange with rounded edge for strength and safety.
F. 20 Gauge steel housing & flashing stands up to high winds, hail, rain and snow.
G. Comes with 5~25 years manufacturer's warranty.
H.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.
