FIRE DAMPER
Model : CFD
Approved 90/180 Min. Fire Rating as per UL-555. The dampers are made of heavy guage galvanised steel having multi blade construction. The blades are fitted with chrome plated shaft and self lubricated phosphorus bronze bushes. The dampers are also provided with jamb seal (compression type) on sides to prevent spread of smoke & fire. The blades of the damper are held in the 'open' position by a high tensile spring and a fusible link. The fusible link is UL stamped and operates at 74 degree C, causing the damper to close in case of fire. Thus the spread of fire through the ducts is prevented.These dampers are installed with G.I. sleeves as an integral part.
