Actuators for fire protection dampers
OpenAir™ actuators for fire protection dampers are at the interface between highly integrated security systems and people. They work extremely reliably especially in emergency situations. Fire smoke remains at its source – for absolute safety for people using the buildings and assets.
Electric motor driven actuators for 2-position control and with spring return to fail-safe position in critical situations.
Highlights at a glance
Two powerful torques for additional safety – 7 Nm or 18 Nm
High reliability thanks to equal values for opening and closing
Fast, easy installation thanks to secure, easy-to-mount, positive shaft collet (square)
Their emergency actuating function returns them reliably to the zero position – if the thermal fuses melt, a power failure occurs or the operating voltage is switched off. This closes the fire protection dampers and thus prevents smoke and flames from spreading through the connected ventilation ducts in an emergency.
