Schneider Electric (Barber Colman) M572-2308 Pneumatic Damper Actuator

The Schneider Electric M572-2308 is a high-performance pneumatic damper actuator designed for the precise modulation of airflow within commercial HVAC systems. This piston-type actuator features a 2-inch stroke and a standard 3 to 12 psig spring range, allowing for seamless integration with pneumatic controllers in both proportional and two-position applications. Built with a rugged glass-filled nylon housing and a durable neoprene rolling diaphragm, it delivers reliable operation in ambient temperatures ranging from -20 to 140 °F. As a veteran-preferred replacement, the M572-2308 is identical to the Barber Colman 2472-010, streamlining retrofits without requiring field modifications to mounting brackets.

Engineered for versatility, the unit utilizes right-angle mounting and comes equipped with a ball joint that accepts a 5/16" push rod for robust mechanical linkage. The internal spring mechanism ensures a spring-return safety function, automatically retracting the actuator shaft upon a loss of supply air pressure to maintain a known fail-safe damper position. Installation is simplified via a standard barbed fitting designed for 1/4" O.D. plastic tubing, supporting a nominal 20 psig supply air pressure (up to 30 psig maximum). For contractors maintaining institutional facilities or vintage air handling units, this actuator provides the consistent torque needed for terminal units, mixing boxes, and unit ventilators.

Key Benefits

• Broad Compatibility: Direct cross-reference for the Barber Colman 2472-010, ensuring zero-downtime replacements in existing systems.
• Durable Construction: Features a high-strength glass-filled nylon body and a resilient neoprene diaphragm for long-term cycle life.
• Fail-Safe Operation: Reliable spring-return capability retracts the shaft when air pressure is lost, protecting system integrity.
• Precision Control: The 3 to 12 psig spring range provides stable, linear response to pneumatic control signals.
• Standardized Fittings: Includes a 1/4" O.D. barbed connection and a ball joint for 5/16" push rods, compatible with most common linkage kits.

Common Questions

Is the M572-2308 a direct replacement for the Barber Colman 2472-010?
Yes, the M572-2308 is the exact functional and physical equivalent of the 2472-010, utilizing the same mounting footprint and technical specifications.

Does this actuator include the push rod ball joint?
Yes, this model includes a factory-installed ball joint designed to accept a standard 5/16" push rod for linkage to the damper shaft.

What is the fail-safe position of this pneumatic actuator?
This is a spring-return actuator that is designed to retract the shaft when supply air is removed or lost, ensuring the damper returns to its normal position.
