Actuators for fire and smoke protection dampers

The ultimate security: your safety

Actuators for fire and smoke protection dampers


These actuators mechanically open dampers with powerful 4 Nm, 7 Nm or 18 Nm within 90 seconds from 0 to 90 degrees and close the dampers with the same torque in 15 seconds. Thus they help to keep escape routes and emergency exits free of smoke for as long as possible. Additionally the actuators come with a spring return function that returns them in emergency situations safely to the zero position and thereby prevents smoke and flames from spreading through the connected air ducts. There are damper actuators with or without thermal fuse at 72 °C or 95 °C available.
