Carrier HF21KJ007 Damper Actuator

The Carrier HF21KJ007 Damper Actuator is a 24V HVAC actuator engineered for precise airflow regulation in residential and commercial zoning systems. Delivering 10 in-lb torque, this unit facilitates a 45-degree rotation, ensuring accurate positioning of dampers within terminal units and air handlers. As a factory-authorized Carrier replacement part, it provides high-precision modulation to maintain stable static pressure and optimize thermal comfort. This heavy-duty component features a durable steel gear train and a NEMA 1 rated housing, designed to withstand the rigorous duty cycles of professional climate control applications. The HF21KJ007 is the direct replacement for the HF21KJ005, DAMPACT45DEG-B, and M9101-AGA-CR01D, offering seamless integration with existing 24VAC control circuits. Its compact footprint and 50/60 Hz frequency rating make it a versatile solution for technicians performing field repairs on Carrier and Bryant zoning systems. This actuator ensures reliable damper motor performance, reducing mechanical stress while maximizing energy efficiency across the ductwork.

• Direct OEM Compatibility: Engineered as a drop-in replacement for HF21KJ005 and M9101-AGA-CR01D, eliminating the need for complex mounting modifications.
• Precise 45-Degree Stroke: Specifically calibrated for 45° airflow control, providing the exact movement required for specialized damper assemblies.
• Industrial Build Quality: Features a corrosion-resistant housing and robust internal gearing to ensure consistent 10 in-lb torque delivery.
• Easy Electrical Integration: Operates on standard 24V power supply (50/60 Hz), making it compatible with most universal zone control panels.
