About this item
  • Outer Diameter of Interface: 175 mm / 6.89 inch; Overall Size: 220 x 220 x 45 mm / 8.66 x 8.66 x 1.77 inch (L*W*T); Color: Red
  • Advantage: Made of durable iron material, which has high hardness and not easy to scratch, resist corrosion, waterproof, moisture-proof and easy to clean, can be used for a long time; When the exhaust starts, the air pressure will push to open the valve for air discharging; after the exhaust stops, the damper valve will automatically close and remain closed all the time to prevent odor from entering your room, making your indoor environment full of fresh air.
  • Instruction: 1. Fix the damper to the vent hole on the wall with spring clips; 2. Then apply sealing glue around the bottom of the backdraft damper; 3. Finally install the vent hose to the damper with pipe clamps and seal with tape if necessary.
  • Application: The backdraft damper is used to prevent the backflow of smoke or exhaust gas through air duct when the ventilation fan is off, it also prevents debris, dust and odor from entering your room. Widely used in dryers, extractors or range hoods, and other HVAC applications. You can install it in your home, kitchen, bathroom, office or living room which needs a ventilation system.
  • Note: Please confirm the outer diameter of the backdraft damper before placing an order. Also, please note that sealing glue is not included.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days โ€” so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
