Fireproof Butterfly Dampers CR120+BFLT230

Fireproof Butterfly Dampers CR120+BFLT230

Circular fire dampers with a fire resistance of 120 minutes. When the temperature in the damper rises above 72 °C, the damper closes with the help of a spring. When closed, the expanding material around the fireblade assures a fire and air-tight seal against hot air and smoke.

There are two models of motor actuators:

  -  BLF230 - It's a 230V actuator WITHOUT a thermal-electrical fuse and is controlled by a fire alarm system.

  -  BLFT230 - It's a 230V actuator WITH a thermal-electrical fuse, which melts when the temperature reaches above 72°С, which in turn automatically closes the damper, using a spring.
