Description
The Siemens 120 Volt, Spring Return Actuator, 2-Position, 62 lb-in, was designed for use in modulating, two-position and three-position control of building HVAC dampers. These actuators are used in constant or vriable air volume installations. They mediate control of return air, mixed air and exhaust. Devices also control face and bypass dampers requiring up to 62 lb-in torque. Actuators are created for applications requiring the damper to return to a fail-safe position where power failure may occur.
The OpenAir direct-coupled spring return electronic actuator is designed for modulating, two-position, and three-position control of building HVAC dampers. Used in constant or variable air volume installations for the control of return air, mixed air, exhaust, and face and bypass dampers requiring up to 62 lb-in (7 Nm) torque. Designed for applications that require the damper to return to a fail-safe position when there is a power failure.
