Abstract
Apparatus, systems and methods of 80/90 CFM ventilation exhaust fans for bathrooms with telescoping side extension brackets and side by side electric driven motor and blower wheel, and being used with or without lights. The exhaust fans can include a single main housing, that allows for a blower housing to support the motor and a blower wheel in a side by side arrangement. The exhaust fans can further include an outside wiring box that is externally located to the main housing. The wiring box can have support male plugs and female receptacles for supplying an electrical power supply to the electric motor and light. The side extension brackets can include telescoping members that allow the exhaust fans to be easily attached to structural members inside of a ceiling so that the exhaust fan has a vent cover attached to the ceiling. Inside of the exhaust fans can be light box with closed sides and bottom which prevents incoming air from passing directly onto the lights. Instead incoming air is drawn to pass around the outside of the light box so that the light box functions as a heat sink reducing the heat generated from the light.
