Description
Accessories - SJK Smooth Flow Backdraft Damper in ø150 or ø200mmDescription: The patented SJK Smooth Flow backdraft dampers are constructed from injection moulded plastic designed with a low resistance gravity damper. Form an excellent seal against backdraft when the fans are switched off. The SJK Smooth Flow damper has the lowest resistance. The pressure loss through the backdraft dampers has to be added to the system resistance before selecting the fan.

Neck came frayed/cut
Size: Large, Color: White
Poor quality. The collar/neck area was cut up/frayed. Never had a chance to return this shirt in the allocated amount of time. Guess we have an expensive rag.
