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.
