RSK.. Backdraft Shutters for In-line Fans

Features

RSK butterfly dampers are designed specifically for use with in-line fans such as those detailed in the selection table. They may also be used as simple backdraft dampers in a duct system.

The flaps are spring-loaded and when the fan is switched off they close providing a seal.

The pressure loss through these units must be added to the system loss before selecting the fan.

The tube is constructed from galvanised steel and the flaps from aluminium.
