GEZE, a leading manufacturer of door and window control systems, has launched a new solution for smoke extraction systems.
The RWA K 600 retractable arm drive can be fitted to emergency exits on escape routes and in the event of a fire it can be used as a fresh air supply which when the fire alarm is sounded the door opens automatically allowing a large amount of air to flow into the building and forcing smoke out.
The powerful drive with high torque opens a door to 908 in less than 60 seconds. Yet the door remains readily accessible due to the freely positioned activation of the lever by means of a pressure roller.
The RWA K 600 is designed for use in supply air systems where large opening angles are required; it is suitable for single and double leaf smoke and heat extraction fresh air doors and can be installed on both the hinge or opposite hinge side.
