Product Overview

Premium Back Draft Damper is installed into ductwork to prevent unwanted outdoor drafts from entering into your bathroom fan, kitchen fan, clothes dryer, etc. Ultimate one way air flow valve allows air to flow out but not back in. It does not rust or require any maintenance. Non-mechanical in-line one way air flow valve that requires minimal pressure to operate, has no moving parts. Sized slightly less than the internal diameter of the duct to slip easily into duct. Rubber gasket provide a friction fit and air-tight seal. Eliminates cold air back drafts in the winter saving heating loss. Eliminates hot air back drafts in the summer saving air conditioning loss. The damper consists of a specially formulated fabric sleeve attached to an outer metal sleeve. The fabric sleeve will allow air to pass through unrestricted in the desired direction of flow without reducing system efficiency. It is silent, produces no metal clanging sounds, tested to UL723 standards and can be installed in solid or flexible ductwork in any orientation. Installs easily - simply slide into duct. Specifically designed to stop back drafts from your clothes dryer, bathroom exhaust fan, kitchen fan, pellet stove, direct vent water heater and direct vent furnace.

    Super frustrating when damper would not fit in vent pipe...
    Super frustrating when damper would not fit in vent pipe at first. Left vent pipe disassembled overnight, then VOILA, it fit! Vent pipe just needed to warm up, we were in the midst of a cold snap (-2 degrees). Damper works great, better than expected!

    Did not fulfill its claims.
    The manufacturer claims this product will slide into existing duct work. It did not. It was the same size as the duct work. I had to modify the product to get it in place. I emailed the company and never got a response.

    No More Draft On My Stovetop
    Had a 6" inlet but 6 incher would not fit...had to go with the 5" and put some two rounds worth of weatherstriping on it to fit snug.....so far it has worked good. No more cold are coming from outside into the house when a cold front would blow thru.

    should have return it.
    the material for the damper was very thin and didn't close down like it should.
