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. Optionally, an end or begin of range switch FDC CFTH can be added to the mechanism. The operating mechanism can be removed easily, for inspection purposes or for replacing the fusible link.
Explanation
CU2 = Rectangular fire damper Rf2h
CFTH = Mechanism
400 = Length damper
200 = Height damper
