Siemens® GCA135.1E Rotary Air Damper Actuator spring-return actuators are used in ventilation and air conditioning plants to operate air dampers and air throttles:

Features of Air Damper Actuator:

For damper areas up to 3 m2, friction-dependent

The actuator must move to the zero position (in emergency position) during power failure in ventilation sections.

Connections can be made to two-position, three-position, or modulating controllers.

For dampers having two actuators on the same damper shaft (tandem-mounted actuators or powerpack).
