With its parallel action blades, the non-return damper is designed to prevent backflow of air. It can also be used to automatically shut-off or isolate a section of the system to prevent ingress of undesirable vapour and vermin. The damper is opened by the air pressure differential between two sides and it closed by help of gravity.

It comes in vertical and horizontal installation configurations.
