Belimo LM24A Damper Actuator

Description

The Belimo LM24A is a robust and efficient damper actuator designed for adjusting dampers in technical building installations. Suitable for air dampers up to approximately 1 m², this actuator ensures optimal airflow and ventilation control in various applications.

 

Simple Direct Mounting: Easily mounts on the damper shaft with a universal shaft clamp, supplied with an anti-rotation device to prevent actuator rotation.

 

Manual Override: Manual override with a push-button is possible; the gear train is disengaged for as long as the button is pressed or remains locked.

 

Adjustable Angle of Rotation: Angle of rotation can be adjusted with mechanical end stops.

 

High Functional Reliability: The actuator is overload protected, requires no limit switches, and automatically stops when the end stop is reached.
