E01 • Motorized circular fire dampers EI60S

downloads

Circular fire dampers with a fire resistance of 1 hour. When the temperature in the damper rises above 72 °C the thermo-electrical link will get triggered and the damper will close. When closed, the expanding material around the fireblade will swell and assure a fire and air-tight seal against hot air and smoke. The tunnel is made out of galvanized steel. The CR60 + BLFT230 fire dampers have a automatic operating mechanism with actuator, with indication of the blade position. An end and begin of range switch is included within the actuator.

Application
