SJK Backdraft Damper (Gravity)
Compared to conventional spring loaded backdraft dampers, the SJK has superior performance characteristics due to its unique design that provides minimal resistance to air flow. The flap closes when the fan is off.
RSK Backdraft Damper (Spring Loaded)
The tube is constructed from galvanised steel and the flaps from aluminium. Flaps are spring-loaded and when the fan is switched off they close providing a seal.
