Out Of stock
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+BFLT230 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.

L (mm) = 400
H (mm) = 600
X = (H-6)/2-70
Y = (H-6)/2-230
