Description

USE

For controlling air dampers with cross section up to 0.8 m² installed in various ventilation and air conditioning systems and performing protection functions.

DESIGN

The electric actuator is provided with a 4 Nm actuating torque and an overload protection.The actuator is installed directly on the air damper shaft. The actuator is equipped with a return spring, which moves the damper to its operating position while tensioning the return spring at the same time. In case of power supply cut-off, the damper moves back to its safe position by the spring energy.The angle of rotation is adjusted by mechanical end stops.
