DMPR-KC211 Johnson Controls Damper Control Accessory

Overview

The Johnson Controls DMPR-KC211 is a high-performance 2-panel damper jackshaft kit engineered for precise torque transmission and mechanical linkage synchronization in commercial HVAC systems. Designed to facilitate uniform blade movement across multiple damper sections, it serves as a direct operational and dimensional replacement for the legacy DMPR-KC205 model, allowing for straightforward retrofits without extensive field modifications.

Features

• Direct Interchangeability: Serves as the exact successor to the legacy DMPR-KC205 system, ensuring direct bolt-on compatibility.
• Enhanced Torque Capacity: Features a robust 1-inch diameter shaft that provides superior torsional strength for large multi-panel damper banks.
• Precision Synchronization: Delivers uniform blade movement across two sections to optimize airflow control and improve air tracking efficiency.
• Deflection Prevention: Designed to eliminate shaft deflection and slippage under high mechanical loads and high-velocity airflow conditions.
• Heavy-Duty Build: Constructed from industrial-grade galvanized materials engineered to withstand continuous modulation.
