The Barber Colman M572-5308 is a pneumatic damper actuator designed for proportional (modulating) control in HVAC and industrial air handling systems. With its spring return functionality, this actuator provides reliable fail-safe operation by returning the damper to a default position when air pressure is lost. Built with durability in mind, the M572-5308 is suitable for demanding commercial environments requiring smooth, responsive airflow regulation.
