CR120-1S+MFUS • Surface mounted circular fire dampers EI120S

Surface mounted circular fire dampers with a fire resistance of 2 hours. The surface mounting ensures a fast (dry) installation. When the temperature in the damper rises above 72 °C the fusible link will break 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 CR120-1S+MFUS fire dampers have a manual operating mechanism with indication of the blade position. Optionally, an end and begin of range switch FDCU MFUS can be added to the mechanism. The operating mechanism can be removed easily, for inspection purposes or for replacing the fusible link.
