M9220-BAA-3 Johnson Controls Damper Actuator

Overview

The Johnson Controls M9220-BAA-3 is a direct-mount, electric spring-return damper actuator designed to position return air, exhaust air, or outside air dampers in commercial HVAC systems. It provides two-position (On/Off) control and delivers a running and spring-return torque of 177 lb-in (20 N-m). Operating on 120 VAC power, it provides reliable, integrated damper control without requiring a complex damper linkage.

Features

• Reversible mounting design allows the actuator to spring return in either direction.
• Electronic stall detection throughout the entire rotation range protects the motor by deactivating it when an overload is detected.
• Direct-coupled mounting with a removable coupler adapts easily to various damper shaft sizes.
• Bidirectional operation simplifies installation and configuration.
• Includes a 48-inch (1.2 m) appliance cable with wire leads for straightforward field wiring.

Specifications

• Control Signal: Two-Position (On/Off)
• Torque Rating: 177 lb-in (20 N-m)
• Nominal Voltage: 120 VAC at 60 Hz
• Rotation Time for 90 Degrees: 24 to 57 seconds (Power On), 11 to 15 seconds (Spring Return)
• Enclosure Rating: NEMA 2 (IP54) aluminum enclosure
• Operating Temperature: -40 to 131 degrees Fahrenheit (-40 to 55 degrees Celsius)

Applications

• Designed for positioning return air, exhaust air, or outside air dampers.
• Used in commercial HVAC and building automation systems requiring reliable two-position control.
• Ideal for setups requiring spring-return fail-safe functionality upon power loss.
