Carrier HF21KJ007 45 Degree Rotation Damper Actuator 24V AC 10 in-lb Torque

The Carrier HF21KJ007 is a compact electric damper actuator designed for precise control of HVAC zone dampers in residential and commercial applications. This non-spring return actuator provides 45 degrees of rotational movement, making it ideal for controlling airflow in ductwork and zoning systems.

Key Specifications:

• Operating Voltage: 24V AC
• Torque Output: 10 in-lb (1.1 Nm)
• Rotation Range: 45 degrees
• Non-spring return operation
• Direct-coupled mounting design
• Suitable for modulating damper control applications

This actuator is compatible with Carrier HVAC control systems and provides reliable, quiet operation for zone damper control. The 10 in-lb torque rating ensures sufficient force to open and close dampers even in high static pressure applications, while the 45-degree rotation angle is optimized for standard rectangular and round damper configurations.
