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.

Features:
- With Back-Draft Flapper Damper
- Large Free Area Reduces Clogging
- Aluminum Construction
- Anodized Finish for Corrosion Protection

#2 Q:   Do birds get in to build nests?
A:   Not that we have heard! If this is a major concern in your area then perhaps look at one of the Seiho hoods that has louvers like the CFX series. https://www.hvacquick.com/products/residential/Bathroom-Ventilation/Discharge-Caps/Seiho-CFX-Series-Aluminum-Hooded-Vent-Caps

#4 Q:   Can the hood of the SFB be removed? The drawing suggests it may be attached with screws rather than being riveted in place.
A:   It is attached in such a way that it cannot be removed without the entire thing coming apart.

#7 Q:   How is the SFB mounted? I see not ref on the specs sheet. The SFB-P can be purchased with mounting holes?

#8 Q:   Does the flapper close completely when the dryer isnt operating? If so, what holds the flapper closed?
