FLAPPER VALVE ADAPTOR FOR A ROOF VENT AND METHOD OF INSTALLING THE SAME
An adaptor for a passive roof vent is presented having a base securable to a roof deck and an integrally moulded stepped collar extending from the base on one side for connecting to different air duct sizes which defines a discharge end for an air flow passageway. A central well is defined by the collar adjacent to and below the base and is open towards the other side of the base and has a hinge pin for at least one flapper valve retained in the well below the base. At least one flapper valve, hinged to the hinge pin, pivots about a closed position to which the flapper valve is biased by gravity and an open position in which the flapper valve is opened by air pressure from below within the air flow passageway. The flapper valve remains partially within the well when the flapper valve is open.
