fire dampers: round dampers
PK-I-C
PK-I-C fire dampers are cut-off dampers intended for installation in ventilation systems or at the end of the duct in front of the ventilation valve.
The fire damper is normally kept open. If a temperature of 72 ° C is reached in the ventilation duct, the thermal release causes closing of the damper. The damper is opened manually or optionally via the TVKC flexible connector.
In the standard version, the dampers do not have limit switches.
