Cosmos Air Distribution Pressure Relief Damper

“COSMOS” Non‐return Pressure relief Gravity Back draft dampers have been specifically designed for use in Air‐conditioning and Ventilation system, these dampers are air operated and are used for air intake and exhaust, and are also used for pressure relief.

Non‐return Gravity Back draft dampers can either be operated by gravity (where pressure or velocity opens and closes the damper) or be motorized to open and close when required. These dampers are composed of a set of horizontally mounted blades, they are normally closed and are free to rotate about the horizontal axis. The blades are manufactured from light weight aluminum sheets. Frame is manufactured from high quality aluminum as well as from galvanized steel.
