Actuators for ventilation are used for smoke vent flaps with pneumatic control, for ventilation spot flaps, and for flaps in continuous skylights. They can be controlled through LT ventilation button and/or mcr P054 or WRS-1b weather control unit.

Used for activating (opening and shutting) ventilation flaps or windows during normal use.

Fire resistance class EI120 (ve ho o→i)S / EI120 (ve i→o) / EI180 (ve o→i)S. The valves are certified for conformity with EN 15650, classified pursuant to EN 13501-3, and tested according to EN 1366-2.

mcr DOR cut-off dampers are intended for installation in automatically operated fire ventilation systems. The devices are used in fire ventilation systems. The dampers prevent fire, smoke and fire gases from spreading to the adjacent zones. During normal system operation, the damper blade is closed. The fire damper blade in the fire compartment is opened, whereas in other areas the blades are closed. Admissible flow velocity in the connected duct is 15 m/s.
