Resideo CPRD8 Damper

The Resideo CPRD8 is a professional-grade Constant Pressure Regulating Damper engineered to maintain consistent static pressure in residential and light commercial multi-zone HVAC systems. This 8-inch round bypass damper features a calibrated adjustment knob, allowing technicians to set the desired system pressure between 0.1" and 1.0" WC without the need for complex pneumatic or electronic controls. The CPRD8 utilizes a counter-balanced weighted arm and a specialized blade design to automatically bleed off excess air as individual zones close, preventing high static pressure from causing coil freeze-ups or excessive air noise. This bypass solution helps ensure HVAC zone system pressure relief while protecting the blower motor and maintaining proper airflow across the heat exchanger. Built for reliability, this barometric bypass damper simplifies the balancing process during commissioning and is a standard requirement for optimizing forced air zoning systems with high-efficiency equipment.

Key Benefits

  • Effective static pressure control that automatically adjusts to varying zone demands through a simple mechanical weighted arm.
  • Engineered for 8-inch ductwork installations, providing a compact footprint for tight mechanical rooms.
  • Reduces airflow noise in zoned systems by redirecting excess supply air back to the return plenum.
  • Compatible with all major 24V zoning panels and variable speed blowers where a dedicated bypass run is required.
  • Calibrated scale allows for precise on-site adjustments to match the specific duct design and blower performance.

Common Questions

How do I set the pressure on the CPRD8?
Adjust the weighted arm and regulator knob based on the static pressure reading at the supply plenum when only the smallest zone is calling. The goal is to maintain the target static pressure specified by the equipment manufacturer.

Can the CPRD8 be installed in any orientation?
No, for the Resideo CPRD8 to function correctly, the damper must be installed in a horizontal or vertical-up configuration to allow gravity and the counterweight to properly regulate the blade position.

What happens if the bypass is oversized?
If the bypass damper is too large, it may bleed off too much air, leading to efficiency loss. The 8-inch model is rated for specific CFM capacities; always verify the total system CFM and the smallest zone's capacity before installation.
