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

#1	Q: What do you mean by No Cap Cover? A: There are 2 cap styles on this page. The SB style does not have the round exterior cover (we call it a cap). THe SFB style has the round exterior weather cover/cap. See the Specs/Pics tab for more info. Asked on 2020-11-28 by Tom
#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 Asked on 2020-10-04 by Jacob
#3	Q: Can the SB be mounted in a soffit facing down? A: No. The damper will only work in a vertical (wall) installation. Asked on 2020-02-03 by Alan
#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. Asked on 2020-01-20 by Bob
#5	Q: Can you paint these to match stucco? A: Yes, they can be painted. We typically powder coat them for durability. Asked on 2019-06-07 by Scott
#6	Q: Is this product available in 8 and 10 in also is it available in galvanized steel A: No, the manufacturer only makes the sizes you see on the page. Sorry. Asked on 2018-04-19 by Bruce
#7	Q: How is the SFB mounted? I see not ref on the specs sheet. The SFB-P can be purchased with mounting holes? A: They have spring clips to hold them in the pipe via friction. The SFB4-PH does have mount holes in the flange front if needed to attach it to the wall face. Asked on 2017-12-03 by R.S
#8	Q: Does the flapper close completely when the dryer isnt operating? If so, what holds the flapper closed? A: It does close nicely, the door is weighted to close properly. Asked on 2014-10-31 by Judy M
