Rheem-Ruud 12URD Round Zone Damper Overview
The Rheem-Ruud 12URD is a 3-wire, round, power open/power close (POPC) zone damper engineered for precise airflow control in residential and light commercial zoned HVAC systems. Designed to integrate seamlessly with compatible zone control panels and thermostats, this damper provides positive, motorized blade actuation in both the open and closed directions — eliminating reliance on spring-return mechanisms and ensuring consistent, dependable performance across every zone.
Key Features
- Power open/power close (POPC) operation for positive two-directional blade control
- 3-wire configuration for compatibility with standard zone control panels
- Round duct design for easy installation in circular duct runs
- Motorized actuator provides reliable zone-by-zone airflow regulation
- Engineered for use in Rheem-Ruud zoning systems and compatible third-party zone controls
- Durable construction suited for long-term residential and light commercial HVAC applications
Application
The 12URD is ideal for multi-zone forced-air HVAC systems where independent room or area temperature control is required. Its power open/power close design makes it well-suited for systems that demand positive damper positioning without spring-return dependency, improving system efficiency and comfort in zoned installations.
