Rectangular fire dampers with a fire resistance of 120 minutes. When the temperature in the damper rises above 70 °C the thermo-electrical link will break and the damper will close. When closed, the expanding material around the fireblade will swell and assure a fire and smoke-tight seal against hot air and smoke. The thin blade is made out of fire resistant calciumsilicate and ensures a relatively high net opening in the damper. The CU-LT+BFLT24 fire dampers are 24V Belimo actuator operated with indication of the blade position. The actuators are connected to a thermo-electrical fuse and equipped with begin-and end of range switch. The mechanism is easily removable for inspection or repair purposes.
For mounting in flexible wall, option +IFW is required. This is a mounting frame that is pre-mounted onto the damper, and ensures its good working when mounted in a flexible wall.
Explanation
CU-LT = Rectangular fire damper
IFW = Mountingframe (only required when mounting in flexible wall)
BFLT24 = Mechanism
200 = Length damper
100 = Height damper
