Rectangular fire dampers with a fire resistance of 2 hours. When the temperature in the damper rises above 72 °C the thermo-electrical link gets triggered and the damper will close. When closed, the ‘palusol’ expanding material around the fireblade will swell and assure a fire and air-tight seal against hot air and smoke. The tunnel and blade are made out of fire resistant PromatectH®. The CU2 + BFLT/BFNT230 fire dampers will have an automatic operating mechanism by means of an actuator with indication of the blade position. An end and begin of range switch is included within the actuator.
Explanation
CU2 = Rectangular fire damper Rf2h
BFLT230 = Actuator 230V with thermo-electric fuse
400 = Length damper
