The AFBUP-S series actuators provide true spring return operation for reliable fail-safe application and positive close off on air tight dampers.
The AFBUP-S is a 120VAC, spring return direct coupled damper actuator with two SPDT switches. It is designed for on-off, fail-safe control of dampers in HVAC systems. Actuator sizing should be done in accordance with the damper manufacturer's specifications. Control is on-off from an auxiliary contact, or a manual switch.
