Descriere
Circular fire dampers with a fire resistance of 120 minutes. When the temperature in the damper rises above 72 C the fusible link will break and the damper will close. When closed, the expanding material around the fireblade will swell and assure a fire and air-tight seal against hot air and smoke. The tunnel is made out of galvanized steel. The CR120 + MFUS fire dampers have a manual operating mechanism with indication of the blade position
