CUSTOMER REVIEWS

Rated 4.9 out of 5 by 7 reviewers.
Rated 4.0 out of 5.0 by Good quality back flow damper I used this to prevent backflow of cold air in a solar space heater. Product worked fine. The way it is made, there is a small space for air to back flow next to the hinge. Would be nice if that was not the case, but it is really no big deal. Opens and closes very without a sound.

Rated 5.0 out of 5.0 by Vent Damper Does What It Is Supposed To This galvanized sheet metal fabrication for a vent damper to prevent cold air from leaking back into vents such as bathroom forced air vents is a good design (I'm an engineer) that uses gravity rather than springs to reclose the damper wings. So, proper orientation with gravity in a vertical position is critical to a proper install. The damper half-rounds are held to the center cross-strut with fabric strips that appear to be synthetic material and the longevity of those fabric strips may be in question, but if they hold up, the only other longevity issue is the foam strip used for the seal ring that also serves to quiet the closing of the half-round damper wings. I purchased this size (6" OD) to match a fan that would fit into an existing recessed light hole cut into the horizontal sheetrock in a bathroom. I use a reducer on the top of this damper to neck down from 6" to 3" to increase velocity and save on vent piping costs. But, I have a limited vertical space to work in between the top of the fan cage and some 2x4 bracing over the drop down I am working in. So, one of those cape-type dampers will simply not work in the space I have to work in. Yes, the damper wings do not fully come together in the open position, which does hinder flow somewhat, but not enough to be of concern when reducing from 6 inches to 3 inches further up. I would recommend against spring-closure type dampers unless you cannot mount this type of damper vertically to use gravity alone to close the damper wings. Invariably, springs and the hinges of the wings will get gummed up with lint and other stuff like hair spray in a bathroom environment and damper operation becomes compromised. This damper is a good choice for vertical installations where space limits the use of cape-type dampers or you are minimizing the cost of such installations. November 19, 2013

Rated 5.0 out of 5.0 by backdraft damper Used this backdraft damper on my range hood vent pipe. It installed into existing duct smootjhly. works perfectly with the range hood. May 8, 2013
Rated 5.0 out of 5.0 by excellent quality very nice, light movement of the damper. Well sealed against backdrafts. Way better than the damper that came with the hood. there is no photo of installed because it is imbedded in the roof insulation. November 12, 2013
Rated 5.0 out of 5.0 by This product is exactly what I needed and was the only one I could find. Excellent product. Fit with no issues and works as it was designed, even with the exhaust fan on its lowest speed. Excellent service through the store. May 21, 2013
