FEATURES
The RSK backdraft dampers are manufactured from steel with
spring actuated aluminium flaps.
The patented SJK Smooth Flow backdraft dampers are
constructed from injection moulded plastic designed with a low
resistance gravity damper.
Both dampers form an excellent seal against backdraft when the
fans are switched off. The SJK Smooth Flow damper has the
lowest resistance of the two models. The pressure loss through
the backdraft dampers has to be added to the system resistance
before selecting the fan.
