2 dampers HT There are different types of dampers: Fire and gas dampers Shutoff dampers Balancing dampers Nonreturn dampers / Pressure relief dampers Blast dampers Airflow adjustment dampers Fire and gas dampers Fire and gas dampers prevent the spread of fire, smoke and gas between fire zones, where people must have the maximum amount of time to react to possible fire. The dampers are typeapproved according to A0 (A60) or H0 (H120). The patented blade structure of the FDB2 dampers have special seals that are effective up to 300 C and thermally activated graphite seals that expand when the heat rises to 150 C in ductwork. These unique safety features ensure air tightness and low leakage to prevent fire, gas and smoke progression in a ductwork.
