The attic fan kit is a simple easy to do kit. It does not require any wiring or any kind of solar expertise. just find the best place in the attic roof to install, fix the solar fan tight and your work is done.

Fan components

The fan blades are made up of aircraft grade aluminum which is powder coated which is pretty much what I recommend, since it can withstand physical impact due to storm or any weather condition.

The 5 blades in the fan lead to lesser work done by each blade which reduces the noise from the fan as a whole. More the number of blades, more quiet is the fan.

The attic fan holds a high impact photovoltaic panel, which can be adjusted for the maximum exposure from sunlight.

The housing which holds the solar panel is made of commercial pure grade aluminum with no seams which prevents leakage during rain.

The motor present in the rotor fan is DC operated and is precision balanced to achieve low motor noise & vibration. The kit contains protective animal screen which is a stainless steel wire mesh which keeps out debris, bugs, birds from entering the setup/attic.

The maximum venting capacity of the exhaust fan is up to 1275 cfms (2000 sf). With a 20 watt module the solar attic fan increases the rate of flow of air to 1200 CFM(cubic feet per minute).
