Johnson Controls M9220-BAA-3 Actuator

The Johnson Controls M9220-BAA-3 is a high-torque, spring return direct coupled actuator engineered for precise on/off damper control in commercial HVACR systems. Delivering a robust 177 lb-in torque, this 120Vac damper actuator ensures reliable positioning for return air, exhaust air, and outside air dampers. Designed as the direct replacement for M9216-BAA-2, it offers a seamless upgrade path with enhanced performance. The unit features electronic stall detection across its entire 93-degree rotation range, protecting the brushless DC motor from damage during overload conditions without the need for end switches. With a power on run time of 24-57 seconds and a rapid 11-15 second spring return, it provides consistent timing under load. The NEMA 2 rated aluminum enclosure is built for longevity in demanding environments. Installation is streamlined via the 48-inch appliance cable and a reversible mounting design, allowing the spring return to be field-configured for either clockwise or counterclockwise orientation.

• Universal Mounting: Fits 1/2" to 3/4" round shafts or 3/8" to 1/2" square shafts using the standard shaft clamp.
• Manual Override: Includes a locking manual crank with auto-release for easy commissioning and emergency positioning.
• High Torque Capacity: 177 lb-in (20 N·m) rating supports single-actuator operation or tandem mounting for up to 354 lb-in.
• Durable Construction: Features a rugged aluminum housing and halogen-free cabling for superior field reliability.

Common Questions

Is the M9220-BAA-3 compatible with my older M9216 series setup?
Yes, the M9220-BAA-3 is the official M9216-BAA-2 replacement. It maintains similar mounting footprints while offering improved brushless DC motor technology for more efficient operation.

Does this model include internal auxiliary switches?
This specific BAA model is an on/off unit without integrated auxiliary switches. For applications requiring end-stop feedback, contractors should verify if the "BAC" variant is required for the specific wiring schematic.

Can I change the spring return direction in the field?
Absolutely. The reversible mounting design allows you to flip the actuator to achieve the desired fail-safe direction (CW or CCW) without needing additional hardware.
