Compatible With: This replacement damper motor actuator is fully compatible with Honeywell's M847D series, including M847D1004, M847D1012, and other M847D series motors. Ideal for use with ZD and ARD dampers. Replace OE: This high-performance actuator replaces Honeywell's OEM M847D motors with an upgraded, durable design that eliminates the failure-prone thin plastic gears in favor of all-metal, precision-engineered gears. High Quality: This actuator features a robust, all-metal gear system for long-lasting reliability. The torque rating of 32 in. oz. (both power open and spring close) ensures consistent performance across its full 90º rotational operating range. Function: Designed for 24 VAC operation, this 2-wire spring return damper motor delivers a quick, reliable 30-second stroke time for motor-driven opening and a 6-second return via the spring. Suitable for both Normally Open (N.O.) and Normally Closed (N.C.) HVAC or venting installations. Package Includes: 1 x Replacement Damper Motor Actuator (24 VAC). Mounting instructions and direct coupling to 5/16" damper shaft for easy installation. (Tip: Using the original Honeywell long set screw ensures a secure and easy installation.)
