Io Hvac Controls RAT-09 Retrofit Air Terminal 9 in

Product Description

The IO HVAC CONTROLS RAT-09 is a 9-inch retrofit air terminal designed for use in variable air volume (VAV) and zoning control applications. This terminal unit controller mounts to existing ductwork and integrates with building automation or zoning systems to regulate airflow in commercial and light commercial HVAC installations. It is installed by licensed HVAC technicians working on retrofit projects where upgrading or replacing legacy terminal controls is required without full duct replacement.

The RAT-09 is suited for retrofit scenarios in commercial office buildings, light commercial facilities, and multi-zone HVAC systems where a 9-inch round duct terminal is present. It is commonly installed when modernizing older pneumatic or manual terminal units to electronic control. This unit fits into existing 9-inch duct openings, reducing labor and material costs associated with full terminal replacement.

Key Features

• 9-inch form factor designed to retrofit into existing duct openings without full duct modification
• Intended for VAV and zoning control applications in commercial and light commercial systems
• Supports integration with electronic building automation and zone control systems
• Engineered for retrofit installations, reducing the need for invasive ductwork changes

Compatibility

Designed as an OEM-style retrofit replacement air terminal for 9-inch round duct terminal applications in commercial and light commercial HVAC zoning systems.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with VAV and zoning control systems. Shut down the air handling unit and de-energize all associated control wiring before beginning installation. Verify duct sizing and confirm the existing opening matches the 9-inch terminal specification prior to mounting. Follow all applicable local mechanical codes and manufacturer wiring diagrams during commissioning.
