F-C2_VA Circular Fire Dampers

Fire dampers are passive fire protection and are designed to utilize compartmentalization to prevent the spread of toxic gases, smoke and fire. By default, F-C2 fire dampers are only supplied with spring loaded activation. In case of fire, the fire damper closes automatically when the temperature of the air in the duct reaches 72°C. The F-C2 damper closes after the melting of the thermal fuse. After the closing of the damper blade, it is mechanically locked in the closed position and can only be opened manually. The inspection can be performed via the air terminal device. F-C2-VA is equipped with a valve (BOR-S, BOR-R, Balance-S, Balance-E, EFF, TFF) for supply or extract air. It provides an easy and compact solution for duct penetrating a fire compartment, ended with an air terminal device.
