Trane ACT0490 Spring Return Rotary Damper Actuator

The Trane ACT0490 is a spring return rotary direct coupled damper actuator designed for commercial HVAC applications. This OEM actuator provides reliable automated control of air dampers in air handling units, variable air volume (VAV) systems, and mixing box applications.

Key Features:

• 24V operation with 90-degree rotation capability
• Spring return (S/R) design for fail-safe operation
• Counter-clockwise (CCW) rotation
• Direct coupled mounting for simplified installation
• Robust construction for long-term reliability in demanding environments
• Compact design for easy integration into HVAC systems

This actuator is engineered to provide precise damper positioning and consistent performance in commercial heating, ventilation, and air conditioning systems. The spring return mechanism ensures the damper automatically returns to a safe position in the event of power loss, making it ideal for critical applications where fail-safe operation is essential.
