Rectangular fire dampers with a fire resistance of 2 hours. When the temperature in the damper rises above 72 °C the fusible link will break and the damper will close. When closed, the ‘palusol’ expanding material around the fireblade will swell and assure a fire and air-tight seal against hot air and smoke. The tunnel and blade are made out of fire resistant PromatectH®. The CU2 + CFTH fire dampers have a manual operating mechanism with indication of the blade position.
