Seiho SB and SFB Series Aluminum Dryer Vents with Backdraft Flapper
Designed for exterior applications, the SFB and the SB have large openings to reduce clogging. Standard with a flapper damper which prevents outside air from back-drafting into the house through the dryer. Both models are suited to exhaust fan applications such as dryer, bathroom, or kitchen exhaust venting. The heavy-gage anodized aluminum construction is corrosion-resistant for years of service. Removable from ductwork for easy cleaning.
