Description
The Schneider Electric (Barber Colman) MK-3141 is a reliable pneumatic damper actuator engineered for precise damper control in commercial HVAC and building automation systems. Featuring a 3 to 13 PSI spring range, this actuator delivers consistent, responsive positioning across a wide range of pneumatic control applications.
Key Features
- Spring range: 3 to 13 PSI for accurate modulating control
- Adjustable stroke: 2″ to 4″ to accommodate various damper linkage requirements
- Spring-return safety action: actuator shaft retracts automatically on loss of air pressure, ensuring fail-safe damper positioning
- Maximum operating air pressure: 30 PSIG
- Air connections: 1/8″ FNPT for easy integration with standard pneumatic tubing and fittings
Application & Benefits
The MK-3141 is ideal for use in variable air volume (VAV) systems, economizers, and other HVAC applications where dependable pneumatic damper control is required. The spring-return mechanism provides an added layer of safety by automatically driving the damper to its fail-safe position whenever air supply is interrupted. The adjustable 2″ to 4″ stroke range offers installation flexibility, allowing technicians to fine-tune linkage geometry for optimal damper performance.
