Carrier DAMPACT90DEGR Damper Actuator

The Carrier DAMPACT90DEGR Damper Actuator is a direct replacement for legacy units including DAMPACT90DEGA, HF21KJ006, and the Johnson Controls M9101 series (M9101-AGA-2N1, M9101-AGA-CR/CRD). Engineered for precision, this 24V damper actuator provides 10 in-lb of torque with a full 90-degree stroke, making it the standard for regulating airflow in variable air volume (VAV) systems and residential zone controls. As an OEM HVAC component, it ensures seamless communication between the zone board and rectangular dampers without the fitment issues common with universal aftermarket parts. This synchronous motor-driven actuator is designed for continuous duty, maintaining static pressure balance across commercial and residential ductwork. When replacing an HF21KJ008 or similar model, the DAMPACT90DEGR offers the exact timing and rotation required to prevent air bypass and optimize climate control efficiency.

Key Benefits for HVAC Professionals:

• Universal Compatibility: Serves as a primary Carrier replacement part for multiple cross-referenced models, reducing truck stock requirements.
• Precise Airflow Control: Features 90-degree rotation designed specifically for rectangular damper blades to ensure tight shut-off and full-open positioning.
• Synchronous Motor Operation: Delivers consistent 10 in-lb torque, preventing overheating and ensuring long-term reliability in high-cycle zoning applications.
• Direct-Coupled Mounting: Simplifies installation on damper shafts, eliminating the need for complex linkages or specialized brackets.

Common Questions:

What models can the Carrier DAMPACT90DEGR replace?
This unit is the authorized replacement for DAMPACT90DEGA, HF21KJ006, HF21KJ008, and Johnson Controls M9101-AGA models. It is the tactical choice for restoring Carrier HVAC equipment to original factory specifications.

Is this actuator suitable for round dampers?
While primarily used for rectangular dampers in VAV and zone systems, it can be utilized in any application requiring 10 in-lb torque and a 90-degree limit, provided the shaft diameter is compatible.

Does this unit include the mounting hardware?
This is a standard damper actuator kit designed for direct-shaft mounting; check your existing shaft dimensions to ensure the collar assembly meets your specific installation requirements.
