Blauberg
The Blauberg 125mm inline backdraft damper fits into a round duct run to let exhaust air out while preventing outside air drawing back in when the fan is off. It works with inline fans on 125mm ducting, helping maintain indoor air quality and limit draughts.
A backdraft damper is fitted in the duct line between the fan and the outlet so 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.
