fire dampers: round dampers

FKRS-EU dampers are designed for automatic or remote (flaps equipped with an actuator with a return spring) to isolate spaces covered by fire in ventilation and air-conditioning systems. These dampers are designed for horizontal and vertical installation and can be installed in building barriers made in light as plaster or traditional technology (masonry or concrete).

The thermal closure of the shut-off valve takes place at a temperature of 72 ° C (optionally 95 ° C). Alternatively, a trigger mechanism can be used with an actuator with a return spring and a thermal switch.

The damper housing is made of stamped sheet metal and is adapted for mounting in round holes without the use of additional reinforcements.

The operation of the damper is independent of the direction of air flow and the position of the ventilation duct.

The damper is terminated on both sides with a lip seal.
