Backdraft damper for models φ39 100 Drim and Planet by the company airRoxy.
It is a simple to install and functional non-return valve suitable for Planet and Drim models with a diameter of 100 mm.
The component is placed at the end of the pipe and secured with two side clips. The plate is made of thin sheet that opens during the fan's operation and closes when it stops.
The return collar is sold in heat-sealed packaging, which must be cut from the white area side and the component carefully removed. Do not pierce the film with your finger.
The non-return valve prevents the reverse flow of air from the duct into our space, thus offering protection from the influx of cold air and unpleasant odors from the duct.
