Description
The backdraft damper with spring-loaded blades is used for shutoff of air flow in the air ducts and prevention of air backdraft during standstill of ventilation equipment. The damper blades are opened with the air pressure and closed with the spring.The unit casing and the two spring-loaded blades are made of polymer-coated steel. The damper placement in a ventilation system should account for the air flow direction. In case of a horizontal installation of the damper, the pivot axis of the blades must be true horizontal. A vertically installed damper is only suitable for air extraction duty. To asemble the Axis-FP fans, use the VRV-AF...400/2 dampers, which are designed to operate at a temperature of 400 °С for 2 hours.
