Review: light weight but works as designed - pretty light weight but I think that's by design. Alum so no rust worries - very light spring action. Fit perfectly in the existing duct work. I wasn't able to use the baffle on the fan I bought for the bathroom so this was a nice alternative.
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.

## Features

- 【Material】The 6 inch backdraft damper is made of a Galvanized steel, the flap leaves are made of aluminum
- 【Installation】The backdraft damper is installed by pushing it into the ventilation pipe as far as it will go. The position of the spring should be horizontal when the flap is installed horizontally so that it can be opened and closed optimally. This also applies to the vertical installation
- 【Function】This airflow regulating backdraft shutter fits over the TD lip and is designed to improve ventilation by preventing air from re-circulating when the fans are not in use
- 【Wide Application】 These backdraft dampers can be widely used in ACs, exhaust fans, extractors, range hoods, heating ducts, vents and other residential, commercial and industrial applications
- 【Note】Back draught valves can be inserted into ventilation ducts which are flexible or non flexible. Cannot be used with plastic ducts as the sizes are different. All dimensions are measured manually, please allow 1-3mm differences

### ⭐⭐⭐⭐⭐ Quick and easy Backdraft fix!
*by P***N on February 4, 2026*

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.
