Johnson Controls M9220-BGC-3 Damper Actuator
$411.00
The Johnson Controls M9220-BGC-3 is a direct-mount, spring-return electric damper actuator with on/off control and two integral auxiliary switches. It delivers 177 lb·in (20 N·m) of running and spring return torque, driving dampers without a separate linkage.
Description
- Direct Mount: Installs onto the damper shaft without linkage.
- On/Off Control: Drives the damper open or closed on command.
- Spring Return: Returns the damper to the fail-safe position on power loss.
- High Torque: Delivers 177 lb·in (20 N·m) drive torque.
- Flexible Power: Accepts AC 24 V or DC 24 V.

Description
The Johnson Controls M9220-BGC-3 is a direct-mount electric spring-return actuator designed for on/off damper control in HVAC systems. Its bidirectional operation eliminates the need for a separate damper linkage, allowing direct installation onto compatible round or square damper shafts using the included shaft clamp.
It operates on AC 24 V at 50/60 Hz or DC 24 V power and includes two auxiliary switches for position indication or switching functions within the selected rotation range. The actuator provides 177 lb·in (20 N·m) of running and spring-return torque and supports tandem mounting configurations for higher torque requirements.
Frequently Asked Questions
What shaft sizes does the M9220-BGC-3 fit?
Using the included clamp, it mounts on 1/2" to 3/4" round or 3/8" and 1/2" square shafts.
What is the actuator's torque output?
A single M9220-BGC-3 delivers 177 lb·in (20 N·m). Mounting two or three in tandem doubles or triples available torque.
What power supply does the M9220-BGC-3 require?
It operates on AC 24 V at 50/60 Hz or DC 24 V, giving flexible compatibility with low-voltage control circuits.
