If you have a problem with unpleasant smells, noise, or draughts flowing backwards within your ductwork. You can use a Kair 100mm Round Connector with a built-in damper to stop these unpleasant odours, noises, or draughts flowing back through your duct. It is also available in 125mm and 150mm plastic or rigid metal.
Plastic Backdraught Shutters By Size
The backdraught damper is a shutter which closes when the fan is not in use. It is great to use when you have two or more extractor fans connected into the same ducting system. This will help prevent cross contamination of your airflow. It will also help if you want to make sure no creepy crawlies climb into your duct run!
You can use this part with either rigid 100mm round pipe (Part: "DUCVKC250"), or flexible 102mm PVC flexible hose (Part: "DUCP0092/102/35"). Easy to install - look at air direction arrow.

To attach to the rigid pipe, just push-fit parts together. If you would like to seal the joint for better airflow performance, you can use mastic sealant (Part: " EVBPINKGRIP"), sealing tape (Part: "DUCVKC273"), or poly-cement (Part: " PLASC250") depending on your personal preference.
To join a flexible hose, simply pull the end of the hose over the connector. Join using a metal hose clip (Part: " DUCVKC264"), quick release worm clip (Part: " GALFIX-QRWC-60-135") , or tape.
Kair Round System 100 (SYS-100) provides superior airflow performance compared to rectangular or flexible duct and should always be considered as a first option if space allows.
