Designed for control of building HVAC dampers, the OpenAir GCA Series Direct‑coupled, Spring Return Electronic Actuators are available in 0 to 10 VDC or 2 to 10 VDC modulating, floating and 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. Models are available with either an appliance cable for wiring in conduit or a plenum‑rated cable for applications where conduit is not required.
