This unit is designed to reduce attic temperatures and remove destructive moisture, thus making your home more comfortable and reducing the load on your HVAC system and lowering your electricity bills.

Life-time, non-transferable limited warranty on parts and defects.

Answer This Question

Great question. I would say 2700 ft.². If you have a gable vent, then I suggest two Gable fans.

    Does it come with an external cover/louvers? There's nothing shown on the product pictures, but it's listed as a part of the description.

    Answer This Question

    It does not come with louvers. It’s designed to go against the existing gable vent in your attic, which should already have louvers on the outside.

      The motor and blade only blows in one direction. However, you can mount the fan at any angle or direction you wish. Hope that helps.

          Is there a on and off switch on the thermostat
          BySep 25, 2025
          1 Answer | 
          Answer This Question

          Well, you wouldn’t necessarily want an on off switch for the thermostat because you want the thermostat to work regardless. However, if you’re asking, can you turn the fan on or off or can you control the thermostat settings? You would need our Wi-Fi controller as an accessory. However, take a look at the fan out of the box. It works great without any other accessories.

              Shipping was fast and arrived with out any issues. Fan install was very easy with predrilled mount spots. Solar panel was also very easy to install and was plug and play with the fan. Plugged it in and the fan started right up. Keep the garage way cooler and dont raise my electrical bill! Its nice to have it auto turn on and not have to worry about it.

              I bought 3 of these to replace old vents on my roof during a roofing project. Once installed they immediately began working. Since my ceiling to roof height is low, I can hear the fans working. Very low sound and I can be very distracted by white noise and do not mind them. Highly recommend as my home is much cooler.

              Works as it should!
              The fan is doing what it’s supposed to! We had a few hot days since installment and the temperature difference between inside and outside was quite noticeable. Would recommend this fan.

                Easy to install, turned on as I was installing it. It's set to come on at 80 degrees, it would be nice if the thermostat was ajustable.

                This was a straight forward install for our storage shed that we do not have power....its very quiet and it cools it down well and turns on automatically when it gets 80 degrees..I did have install and 1 inch border so the fan would not hit the gable that I bought as well
