Honeywell M847D-VENT Damper Actuator, 24VAC, 60Hz, 7W, Spring Return

Condition: New

The Honeywell M847D-VENT is a low-voltage, spring-return damper actuator designed for ARD, EARD, and ZD zone dampers. It operates on 24VAC and features a power-open, spring-closed mechanism for reliable ventilation control. This actuator includes an anti-rotation and drive shaft extension, allowing direct mounting to 7/16-inch diameter coupling-style dampers. It also has adjustable range stops for precise airflow control. The M847D-VENT serves as a direct replacement for the Honeywell M847D1004 and is commonly used in fresh air ventilation systems.
