Backdraft Damper (Spring Loaded)
RSK butterfly dampers are designed specifically for use with high pressure in-line fans and 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 tube is constructed from galvanised steel and the flaps from aluminium.
