Abstract
Apparatus, systems and methods of 50/60 CFM exhaust and ventilation fans for bathrooms with flaps/ears that allow the housings to mount directly to joists and/or other structural members inside of a ceiling or inside of a wall. The housing can include a mounting plate having a motor with attached impeller thereon, wherein the mounting plate with motor and attached impeller can be removed as a single unit from the housing for accessing and inspecting interior wire connections during inspection and for ease in replacing parts such as burned out motors overtime.
