Circular fire dampers with a fire resistance of 120 minutes. It comes with a servomotor (24V), which keeps the damper opened when there is a signal from an outside source. Once the signal is not received, the fire blade closes the damper 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.
It also comes with a thermo-electric fuse, which melts once the temperatures reach 72°С, thus allowing the blade to close the tunnel with the help of a spring.
The models BFLT24 are the smaller ones that have a maximum length and height of 1200 mm and the BFNT24 go from 1250 mm and up.
