Abstract
Apparatus, systems and methods of 110 (one hundred ten) CFM (cubic feet per minute) generating ventilation fans for bathrooms with grill covers and with or without lights in the grill covers. Spring clip type washers can attach the grill covers to the housings. Suspension brackets directly attached to outer side walls of the housing can support the housings. One suspension bracket can be mounted on a bottom wall of the housing and another suspension bracket of equal length can be mounted on a side wall of the housing that is oriented perpendicular to the bottom wall. Bent flanges on the suspension brackets can be on opposite ends of the respective brackets. A lens cover can cover a light box that holds light sources centrally located in the grill cover. The grill cover can include vent openings that allow incoming air to bypass the light sources that can be located inside of the light box.
