Schneider Electric (Barber Colman) M572-3308 Damper Actuator

For HVACR contractors maintaining legacy pneumatic systems, the Schneider Electric (Barber Colman) M572-3308 pneumatic damper actuator provides essential reliability for air control dampers in residential and commercial air handling units. This unit is the designated M572-3055 replacement and also replaces the 2472-030 industrial actuator, ensuring seamless integration into existing pneumatic control systems without extensive modifications. Operating on a 5 to 10 psig spring range, this actuator provides proportional control for mixing boxes, fan coil units, and unit ventilators.

The M572-3308 features a 2-inch stroke and is engineered with a glass-filled nylon housing and a neoprene rolling diaphragm for durability in HVAC automation applications. The right-angle mounting configuration allows for flexible positioning in tight mechanical spaces, while the included ball joint is factory-set to accept standard 5/16" push rods. The internal spring is designed to retract the actuator shaft automatically upon a loss of air pressure, providing a predictable fail-safe state. For quick field connections, the unit includes a barbed fitting for 1/4" O.D. plastic tubing.

Key Benefits:

• Universal Compatibility: Serves as a direct drop-in for Schneider Electric pneumatic actuators including models M572-3055 and 2472-030.
• Fail-Safe Operation: The spring-return mechanism ensures the actuator shaft retracts safely if the 20 psig supply air is interrupted.
• Rugged Construction: Built to withstand ambient temperatures ranging from -20 to 180°F, ideal for diverse industrial damper control environments.
• Precise Response: Optimized for a 5 to 10 psig control signal to provide linear and accurate damper positioning.

Common Questions:

What is the direct replacement for Barber Colman 2472-030?
The M572-3308 is the manufacturer-recommended upgrade and direct replacement for the obsolete 2472-030 and M572-3055 models.

Can the M572-3308 be used for multi-zone HVAC systems?
Yes, this proportional damper actuator is specifically designed for use in multi-zone, heating, ventilating, and VAV terminal boxes.

Does this actuator include the push rod for installation?
It includes the ball joint for a 5/16" push rod, but the push rod itself and additional linkage components are sold separately depending on your specific damper shaft requirements.
