Description & Specs

The Blauberg 100mm inline backdraft damper fits into a round duct run to let exhaust air out while stopping outside air drawing back in when the fan is off. It works with inline fans on 100mm ducting, helping maintain indoor air quality and limit draughts.

  • Size: 100mm
  • Type: Inline backdraft damper
  • Material: ABS plastic
  • Colour: White
  • Back draft stopper: Yes
  • Compatibility: Round ducts
  • DIY install: Yes

A backdraft damper is fitted in the duct line between the fan and the outlet so that air flows one way only. As contaminated air is pushed out, the damper closes against incoming air, which is why it is a useful addition to bathroom, laundry and kitchen exhaust runs.

Perfect gift — loved it

Bought this as a replacement for one I have had for years and I am glad I upgraded. The new one is noticeably better. Had a tracking number within a few hours of ordering. Packaging was excellent, nothing damaged. Already told a few mates about this site. Great prices and genuinely fast shipping.

Great value for money

Spent a while looking for the right Blauberg 100mm and this kept coming up as the best value. I can see why — quality is impressive for the price. Delivery took just 2 days to Townsville which is great. Packaging was solid and everything intact. My partner and I both use it daily now. Highly recommended.
