Vent fan location locate roof mounted fans on the back of the roof below the ridge but not so high as to be visible from the front of the house in the middle of the main part of the attic.
Attic fan cfm rating.
You d need an attic fan rated at approximately 720 cfm.
I read that venting is important.
If you have 1 200 cubic feet of attic the calculation is 1 200 x 0 6 720.
As the attic cools the smart fan will automatically cycle down to lower speeds the lowest being 1 000 cfm which only uses 15 watts of energy resulting in a cheaper air conditioning bill and cooler home temperature temperatures can drop as much as 50 degrees these two factors make it an excellent energy and cost saver.
To facilitate faster air exchange would necessitate choosing a fan with a higher cfm.
Divide the cubic feet measurement by the cfm rating assigned to the fan.
