The IO HVAC CONTROLS RAT-06 is a 6-inch retrofit air terminal designed for use in VAV (variable air volume) and constant-volume HVAC distribution systems. It provides a field-ready solution for replacing or upgrading existing air terminals without requiring full duct replacement. Measuring 11 x 14.25 x 13 inches and weighing 7.25 pounds, the RAT-06 is sized for straightforward installation in commercial and light commercial applications. HVAC technicians and mechanical contractors are the primary installers for this type of equipment.
The RAT-06 is suited for retrofit projects where an existing 6-inch round duct collar is already in place. It is commonly used in office buildings, retail spaces, and light commercial facilities undergoing HVAC system upgrades or control modernization. The compact footprint and retrofit-oriented design reduce labor time compared to full terminal replacements that require duct modification.
Designed as an OEM-style retrofit replacement air terminal for 6-inch duct collar applications in commercial HVAC air distribution systems.
Installation should be performed by a licensed HVAC technician or mechanical contractor in accordance with applicable mechanical codes. Shut down and lock out the air handling unit before disconnecting or installing the air terminal. Verify duct collar alignment and secure all connections per local mechanical code requirements before restoring system airflow.
