CUSTOMER REVIEWS

Rated 4 out of 5 by 1 reviewer.
Rated 4 out of 5 by Damper works as described to prevent back drafts I used this in the exterior exhaust vent I added to my microwave oven, which ventilates the top of the stove. It works well in my vertical vent configuration, where the fan pushes the air straight up, and the damper closes due to gravity when the fan is not running, which stops cold air from coming in. It has a foam-like seat, which stops almost all reverse air flow. The damper is split into 2 half-circles, which pivot around a center support to open or close. January 3, 2012
