Johnson Controls M9220-BAA-3 120V Two-Position Spring Return Damper Actuator 177 lb-in

The Johnson Controls M9220-BAA-3 is a 120 VAC, two-position (on/off) spring return damper actuator. It is also called an electric spring-return damper motor. It is built to position dampers in HVAC systems and delivers 177 lb-in (20 N·m) of torque.

Key Features:

• 120 VAC, 60 Hz power
• Two-position (on/off) control
• Spring return, so the damper returns to its rest position when power is removed
• 177 lb-in (20 N·m) running and spring-return torque
• Power-on run time of 24-57 seconds
• Direct-mount design that does not need a damper linkage
• Reversible mounting lets the actuator spring return in either direction

This actuator suits return air, exhaust air and outside air damper applications that need reliable two-position control with a fail-safe spring return.
