Resideo - Honeywell Home M847A1072 Draft Damper Actuator

Draft Damper Actuator for solid-fuel furnace and boiler control delivers precise airflow in HVAC installations. The Resideo–Honeywell Home M847A1072 model combines low-voltage SPST (2-position) operation with spring-return for dependable cycling. Operating at 24V AC, it offers 45-degree rotation, 1.9 in-lb torque, and a compact size (2-5/8 in W x 3-5/16 in D x 3-1/2 in H). The unit is designed for foot mounting, includes a 3.8 inch linkage chain, and provides a 20-second run timing. It supports ambient temperatures from 40 to 125°F, making it suitable for demanding HVAC environments. This actuator is ideal for HVAC retrofits and new installations, delivering reliable damper positioning, quiet operation, and compatibility with standard duct dampers. Its rugged construction and precise torque help maintain accurate damper alignment across cycles, reducing energy loss.
