Io Hvac Controls RAT-12 Retrofit Air Terminal 12 Inches

Product Description

The IO HVAC CONTROLS RAT-12 is a 12-inch retrofit air terminal designed for integration into existing HVAC duct systems. Air terminals regulate airflow at the zone level, directing conditioned air into occupied spaces while allowing control systems to modulate volume or direction as needed. The RAT-12 is sized for 12-inch duct openings, making it a practical replacement or upgrade component for retrofit projects where duct infrastructure is already in place. Licensed HVAC technicians performing zone control upgrades or balancing work are the primary installers of this type of terminal.

The RAT-12 is suited for retrofit applications in both residential and light commercial HVAC systems where an existing 12-inch duct opening needs a compatible air terminal. It is commonly installed during zone system upgrades, equipment replacements, or air distribution reconfigurations where the existing ductwork is retained and a new terminal is needed to interface with updated controls or damper systems.

Key Features

• Sized for 12-inch duct openings for direct retrofit fitment
• Designed to integrate with zone control and air distribution systems
• Retrofit-ready design minimizes modification to existing ductwork
• Suitable for residential and light commercial HVAC applications

Compatibility

Designed as an OEM-style retrofit replacement air terminal for HVAC systems with 12-inch duct openings requiring zone-level airflow control.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with duct system design and zone control wiring. Power to the air handling unit and any associated control boards should be shut off before beginning installation. Follow local mechanical codes and manufacturer wiring guidelines when connecting the terminal to the control system. Verify duct opening dimensions before installation to confirm proper fit.
