T-bar diffusers consists of a coated steel casing with extruded aluminum center tee (minimum 2 slot) and pattern controllers. Air pattern controllers are available in multiple styles to provide various air patterns with a high induction ratio for a high degree of thermal comfort. Matching return diffusers are available to complement supply units and maintain the architectural appearance throughout the space.

The curved adjustable pattern controllers provide a consistent horizontal air pattern. Factory set pattern controllers also offer field adjustability for horizontal left or right airflow, or vertical airflow with the removal of the pattern controllers.
