Back Draft Dampers

Inline back draft dampers. 

Our back draft dampers are an ideal way of stopping cold air entering through ducts and will also help retain heat in your home. 

Backdraft dampers also called non-return dampers allow the air to pass in one direction only. The flaps are pressed against a foam seal when closed to reduce the operating noise in the ductwork.

The flap are held closed with a spring that makes it possible to be installed horizontal or vertical. 

Available in 100mm. 125mm, 150mm 160mm & 200mm
