Io Hvac Controls CRD-07 7 Inch Retrofit Damper

Product Description

The IO HVAC CONTROLS CRD-07 is a retrofit zone damper designed to replace existing Carrier and Bryant round damper assemblies without requiring full duct modification. Measuring 7 inches in diameter with a depth of 8 inches, this damper fits directly into compatible round duct openings and connects to standard zone control systems. It is designed for installation by licensed HVAC technicians performing zone system upgrades or OEM damper replacements in residential and light commercial forced-air systems. The unit weighs 2.5 pounds, keeping handling and installation straightforward in tight duct chases.

The CRD-07 is suited for residential and light commercial zoning applications where Carrier or Bryant round duct dampers require replacement or upgrade. It is particularly useful when an existing damper has failed and a direct retrofit is preferred over a full duct section replacement. The compact depth of 8 inches allows installation in duct runs with limited clearance. This damper integrates with zone control boards and panel systems that accept standard actuator wiring for open-close or modulating control.

Designed as a retrofit replacement damper for Carrier and Bryant round duct damper applications. Specific compatible model numbers were not provided in the product data; verify the existing damper diameter and actuator interface against the CRD-07 specifications before ordering.

Installation Notes

Installation should be performed by a licensed HVAC technician. Shut down the air handling unit and de-energize the zone control panel at the circuit breaker before removing the existing damper. Confirm duct diameter and actuator wire connections match the replacement unit prior to installation. Follow all applicable mechanical and electrical codes, including local jurisdiction requirements for low-voltage control wiring.
