Schneider Electric (Barber Colman) M572-5311 Actuator

The Schneider Electric (Barber Colman) M572-5311 is a high-performance pneumatic damper actuator engineered for precise proportional or two-position control in demanding HVACR environments. Designed to operate within a 8 to 13 psig spring range, this unit features a robust 2-inch stroke and is a direct, identical replacement for the Barber Colman 2472-140. For technicians working in tight mechanical spaces, the right angle mounting configuration simplifies installation on 1/2" damper shafts, and the included complete linkage ensures a secure mechanical connection without additional sourcing. The fail-safe spring return mechanism automatically retracts the actuator shaft upon a loss of control air pressure, protecting the system from uncontrolled airflow. Built with a 1/4" O.D. barbed fitting for standard plastic tubing, the M572-5311 actuator provides the reliable torque and positioning accuracy required for effective HVAC airflow control in commercial and industrial air handling units.

• Universal Compatibility: Fully interchangeable with the legacy Barber Colman 2472-140, facilitating seamless drop-in replacements.
• System Protection: Integrated spring return fail-safe ensures dampers return to a predetermined position during pneumatic failure.
• Simplified Integration: Includes a factory-supplied linkage kit tailored for 1/2-inch shafts, reducing field assembly time.
• Flexible Installation: The right-angle design allows for pneumatic actuator mounting in restrictive ductwork and equipment clearances.

Is the M572-5311 compatible with my existing Barber Colman system?
Yes, the Schneider Electric M572-5311 is the exact functional and physical equivalent of the 2472-140, designed to interface with standard 1/4" plastic pneumatic lines.

What happens if the air supply pressure is lost?
This pneumatic damper actuator features a mechanical spring that automatically retracts the shaft when air pressure drops below the 8 psig threshold, ensuring safe system orientation.

Does this unit require a separate linkage kit?
No, this model is shipped complete with the necessary linkage hardware for a standard 1/2-inch damper shaft, allowing for immediate installation on most HVAC control dampers.
