Is this available in 3 inch size? and will it work for a downward facing soffit vent??

Asked by: Steve1927

Couple questions about this damper: is it a spring loaded butterfly-plates type? And is there a gasket that goes around its exterior circumference for a tight friction fit within the duct? Thanks.

Atmosphere Back Draft Damper - 8-in is rated 4.0 out of 5 by 4.
Rated 5 out of 5 by from Works perfectly The kitchen is noticeably warmer now that I have installed this dampener. It didn't take much effort other than some wire snips to trim the duct above the range hood to give this room to fit. Add some foil tape and you're in business. I can see that it opens when the fan is turned on and silently closes when the fan blades stop moving. Totally worth the money for the kitchen to no longer be cold.

Rated 1 out of 5 by from Not worth the price Bought this damper to replace one that was broken in my kitchen exhaust duct. Total piece of junk. Flimsy sheet metal pathetic construction. Damper blades blew off within the fist hour and the airflow is not particularly high. Don't buy.
