CR120+BLFT24

Circular fire dampers with a fire resistance of 120 minutes. When the temperature 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. The CR120 + BLFT24 fire dampers have a automatic operating mechanism with actuator, with indication of the blade position. An end and begin of range switch is included within the actuator.
