Abstract
Apparatus, systems and methods of generating 70 (seventy) CFM (cubic feet per minute) from ventilation fans for bathrooms with flush mount lights and having the motor partially inside and beneath the blower wheel. A one piece or multipiece housing for the bath fan can be attached to joists in the ceiling by a long telescoping mounting bracket, and a short telescoping mounting bracket that are each directly mounted on opposite outer side walls of the housing. A decorative pan about the light can have vents that receive the incoming air into the fan, which is exhausted therefrom by the motor driven blower.
