Fire dampers

General information

FKR-EU

Functional description

In the event of a fire, fire dampers shut

automatically to prevent the propagation

of fire and smoke through ductwork to adjacent

designated fire compartments. In the event of a

fire, the damper is triggered at 72 °C or at 95 °C

(use in warm air ventilation systems) by a fusible

link. The release mechanism is accessible and

can be tested from the outside. Both regular

limit switches and explosion-proof limit

switches are available for zones 1 and 2

(gases, mists, vapours) and for zones 21 and 22

(dusts) to indicate damper blade positions.
