Stainless Steel Fire Dampers, Color : Silver

Fire dampers are designed to protect duct penetrations and transfer openings in fire rated walls, barriers, partitions, or floorceiling assemblies. Model FD is for use in HVAC systems that shut down in the event of fire, while model DFD is for use in HVAC systems that remain operational in the event of a fire. Upon temperature elevation, the dampers will automatically shut, preventing the spread of flames. 1 ½ and 3 hour rated fire dampers are available, in fusible link temperatures of 74ºC (165ºF), 100ºC (212ºF), and 141ºC (286ºF).
