Non Return Dampers

Non return damper is a HVAC damper used in areas where air is supposed to flow only in one direction. Non return dampers can be mounted on the wall or duct, depending upon the application. They are most commonly found being used in front of the fans where the blades are opened only when the fan starts and blades close due to gravity when the fans stops.
