Johnson Controls DMPR-KC212 Jackshaft Kit

The Johnson Controls DMPR-KC212 Jackshaft Kit is a critical component for high-torque HVAC damper linkage applications, specifically designed for 3-panel damper configurations. Featuring a 1-inch diameter jackshaft, this kit ensures rigid mechanical transmission and precise blade positioning in heavy-duty commercial airflow systems. Engineered to integrate seamlessly with CD-2500 and CD-2100 series dampers, the DMPR-KC212 eliminates slippage and reduces mechanical backlash, providing reliable operation under high static pressure. Utilizing galvanized steel construction for durability and corrosion resistance, this damper hardware kit is essential for contractors retrofitting or installing multi-panel assemblies where synchronous blade movement is required Top-tier commercial HVAC control performance relies on the robust connection points provided by the DMPR-KC212, ensuring your proportional damper actuators maintain accurate calibration across the entire stroke. By consolidating the drive force across three panels, this Johnson Controls jackshaft assembly optimizes system efficiency and prevents uneven air distribution within the ductwork.

Technical Advantages

• Compatibility: Engineered for Johnson Controls multi-panel dampers and standard 1-inch drive pins.
• Load Distribution: Effectively manages the torque requirements of 3-panel damper systems without mechanical deformation.
• Structural Integrity: Precision-machined 1" diameter shaft prevents bowing or flexing during high-velocity airflow cycles.
• Simplified Installation: Designed for field-mount applications to streamline damper linkage synchronization.

Common Contractor Questions

How do I ensure the DMPR-KC212 is compatible with my existing damper?
This kit is specifically designed for Johnson Controls 3-panel dampers requiring a 1" diameter jackshaft. Verify your current drive pin size and frame width to ensure the coupling and shaft lengths align with the damper's mechanical footprint.

Can this jackshaft kit be used with non-Johnson Controls actuators?
Yes, provided the damper actuator is rated for the total square footage and torque requirements of the 3-panel assembly and includes a 1-inch shaft adapter or universal clamp.

What maintenance is required for the DMPR-KC212 assembly?
Regularly inspect the set screws and linkage connections for tightness. While the galvanized finish protects against surface corrosion, ensure the jackshaft bearings or bushings remain free of debris to prevent excessive friction.
