KMC Controls MCP-3631-3001 Pneumatic Rotary Damper Actuator 5-10 PSI 3/8" Square Shaft

The KMC Controls MCP-3631-3001 is a pneumatic rotary damper actuator designed to position VAV terminals and other small dampers in HVAC systems. This direct-coupled actuator features a 5 to 10 psi spring range and is specifically configured to mount to 3/8-inch square damper shafts.

Key Features:

• 5 to 10 psi operating range (34 to 69 kPa)
• 3/8-inch square shaft mounting configuration
• Maximum air pressure: 30 psi
• May be mounted with either side toward damper to allow clockwise or counterclockwise rotation
• Non-rotation bracket supplied with actuator
• Variety of options available to lock the actuator's drive hub to the damper shaft

Technical Specifications:

• Net force exerted at 18 PSI: 85 lb
• Net force exerted at 0 PSI: 42 lb
• Operating PSI range: 0 to 20
• Clean, dry control air required

This pneumatic actuator provides reliable, proportional control for VAV boxes, terminal units, and small damper applications in commercial HVAC systems. The spring return design ensures fail-safe positioning during power loss conditions.
