Schneider Electric (Barber Colman) M572-5308 Pneumatic Damper Actuator

The Schneider Electric M572-5308 is a heavy-duty pneumatic damper actuator designed for precise air control in commercial HVACR systems. Built to replace the legacy Barber Colman 2472-040, this unit features a 2-inch stroke and a robust 8 to 13 psig spring range, ensuring reliable performance in demanding throttling or two-position applications. Its right-angle mounting configuration and included ball joint, which accepts a 5/16-inch push rod, provide the necessary flexibility for tight mechanical rooms and complex damper linkages. Professionals rely on this spring return actuator to fail-safe by retracting the shaft upon a loss of control air pressure, protecting equipment and maintaining system integrity. The integrated barbed fitting for 1/4-inch O.D. plastic tubing facilitates quick field connections, making it a standard choice for technicians upgrading or maintaining existing pneumatic control loops.

• Direct Replacement: Fully compatible and functionally identical to the Barber Colman 2472-040, streamlining retrofits.
• Fail-Safe Protection: Reliable mechanical spring return ensures the actuator shaft retracts during supply air failure.
• Standardized Fit: Includes a factory-installed ball joint specifically machined for 5/16-inch damper rods.
• Durable Construction: Engineered for industrial environments with high-quality seals to prevent air leakage and pressure loss.
• Easy Installation: Features a simplified barbed fitting for standard 1/4-inch O.D. tubing and a versatile right-angle mount.

Is the M572-5308 compatible with older Barber Colman systems?
Yes, this model is the direct technical equivalent to the Barber Colman 2472-040, allowing for a drop-in replacement without modifying the existing linkage or air lines.

What is the primary function of the 8-13 psig spring range?
This specific spring range dictates the pressure required to move the actuator. It is typically used for sequencing multiple actuators or ensuring enough force is applied to overcome damper friction and static pressure.

Can I use different tubing sizes with this actuator?
The unit comes with a hard-barbed fitting designed for 1/4-inch O.D. plastic tubing. If your system uses different diameters, a standard pneumatic adapter will be required to maintain a leak-free connection.
