Features

  • MaterialThe 4 inch backdraft damper is made of a Galvanized steel with powder coat, the flap leaves are made of aluminum, while the Axis and spring are made of stainless steel.
  • InstallationThe 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.
  • FunctionThis 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.
  • NoteBack 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.

    • Bathroom Vent Fan
Size Name: 4 Inch Color: Sliver
This worked perfect. One end went inside the vent pipe to the outside and the other side went into the flex hose inline with the vent. Took longer to pry up the attic boards than to install this. It stopped that popping noise from the vent fan in the wind. The metal on this is very thin and I can see how some got damaged in shipment. That being said it does work very well. Make sure you use that tape that seals the seam in duct work and to not struggle with the clamps use a clamp that is for 4-6 inch or 4-5 inch it depends on who made it, that way you do not struggle with putting the clamp on to secure everything. Hope this review helps. Steve ... show more

    • Easy to Install; Works Well
Size Name: 10 Inch Color: Sliver
I should have installed one of these backdraft blockers years ago! It was very easy to install and fit perfectly in my 10” range vent pipes. I’m looking forward to a more comfortable kitchen and lower energy bills in the winter months.

    • Installation
Size Name: 6 Inch Color: Sliver
The flaps would rub against the bottom of the damper. I wrapped a paper clip around the bottom part of the rod to make a washer and cut off the excess. This raised the flaps high enough so they no longer rubbed. The damper must be installed with the flaps oriented vertically (like a door). When connecting the damper to the duct work, the crimped end off the existing duct will not fit into the damper so the crimp needs to be cut off and the damper will slide into the duct. When installing a sheet metal screw, there's no issue on the supply side but on the exhaust side the screw must be either at top dead center or bottom dead center so it will not interfere with the flaps opening. Once installed, the damper worked great and stopped the cold outside air from entering the stove exhaust. ... show more

    • Great Buy
Size Name: 4 Inch Color: Sliver
I was worried this would be restrictive to my air flow but it's hardly noticeable. It opens easily. Working great venting my grow tent outside. It blocks all air and bugs from getting in.

Size Name: 4 Inch Color: Black
Awesome product. Works just like it is supposed to. Used for bathroom vent fan, laying in a horizontal position. Slid right into flexible 4 inch ducting. Super happy with this product.

    • Exactly 6" so did not slide into existing 6" duct
Size Name: 6 Inch Color: Sliver
There is no crimped edge, fine. But was expecting to be a few mm less than 6" duct it is supposed to slide onto or into. Nope. It's exactly the same size. Had to manually crimp to make it fit. It is extremely sturdy, beyond what it needs to be, so this was a long and painful process. Used metal duct tape to seal the joint later. Would have returned if it weren't a pain to go to the hardware store. The flaps have a rubber seal so no banging. They seem to be made of aluminum, which honestly this whole thing should have been made out of. No need to be heavy duty and impossible to fit. ... show more

    • Very effective
Size Name: 4 Inch Color: Sliver
Easy to install. Made a huge difference in the cold air situation in our laundry room. Internal sponge padding makes a great seal from the elements.
