Descriere
Circular fire dampers with a fire resistance of 120 minutes. When the temperature of the thermo-electric fuse in the damper rises above 72 C the damper will close. When closed, the expanding material around the fireblade will assure a fire and air-tight seal against hot air and smoke. The tunnel is made out of galvanized steel.
