Belimo's GM damper actuators are a series of 40 Nm actuators without safety function for damper movement in building installations. Rotary actuators with GM power cable are suitable for air dampers up to approx. 8 m2. The series includes: GM24A, GM230A, GM24A-SR.
The GM series damper actuators are easy to mount directly to the damper shaft using a universal mounting clamp, supplied with an anti-rotation strap. Manual operation is possible after pressing the button (the gear remains disengaged until the button is released, the pressed button can be locked).
The angle of rotation is adjusted using mechanical stops. The actuator is overload protected, requires no limit switches and stops automatically when it reaches the limit stop.
