Siemens GCA161.1U OpenAir Spring Return Electronic Damper Actuators fail-safe 2 Position, Standard Cable. Dual Aux. Switches Only.
Designed for control of building HVAC dampers, the OpenAir GCA Series Direct-coupled, Spring Return Electronic Actuators two-position (on/off) control models. The OpenAir GCA Series Damper Actuators are ideal for constant or variable air volume installations for the control of return air, mixed air, exhaust, and face and bypass dampers that require up to 160 lb.-in. (18 Nm) torque. The actuators are designed for applications where the damper is required to return to a fail-safe position when there is a power failure.
