Home Ventilating Institute (HVI) recommends one square foot of open air inlet per 300 cfm of fan capacity.

Your attic fan installation will create a screened opening into your attic space. During a heavy rain storm there could be a light spray of rain into this attic space. This is a normal condition with all attic ventilators and will not cause any damage to the structure. We recommend that you do not store any valuable articles directly under the fan opening in the roof. During extreme rain and wind storms you may want to turn on your attic ventilator to prevent excess moisture accumulation in your attic. 7.
