Review: Perfect for Low CFM Installs. Works great! - Perfect for my installation. Too many of these type dampers have very stiff springs and it will not work with low CFM air flows. These are great. You can blow at them with your mouth and get them to open. And they seal very well. I use them for air circulation between rooms with fans set to about 60 CFM. The last ones I got restricted about 80% of the air. These only restrict maybe 10%. This is key for low CFM situations like bath exhaust fans, for instance.
Review: Quick and easy Backdraft fix! - This draft blocker worked perfect. I was concerned it wouldn't fit inside my old pipe and yet have my old elbow Go over it. It works great to prevent the cold air from going down my dryer vent. I was having trouble with condensation developing on the vent and leaking on the floor. This solve that problem I would recommend it for anybody.
