Circular fire dampers with a fire resistance of 120 minutes. 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 CR2 + CFTH fire dampers have a manual operating
mechanism with indication of the blade position.
