150mm Backdraft Damper (Draft Stopper)

Inline draft stoppers assist in preventing backflow from entering ventilation systems. They are ideal for installation in ducted bathroom fan kits exhausting out through the roof. Manufactured with an internal spring-loaded butterfly damper, the damper opens when air passes through and closes when the venting system is not in use.
