Electric actuator VENTS LM230A | official VENTS website

Description

APPLICATION

The SM series actuators with actuating torque 5 Nm are designed for controlling air dampers with cross section up to 1 m² installed in various ventilation and air conditioning systems.

CONTROL

The LM24A, LM230A models are controlled by the three-point control system.
The damper is opened or closed by the single-circuit control.

DESIGN

The actuator is installed directly on the damper axis and locked with a special spindle clamp to prevent its turning-through.
The actuator overload protection stops the actuator once it reaches the end positions.
In case of pressing the button on the actuator housing the gear is disengaged and the damper changes into manual operation mode.
The turning angle is adjusted by mechanical end stops.
