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 ice-tong style adjustable pattern controllers provide a full 180° range of air pattern adjustment for both horizontal and vertical set points. When set for a horizontal air pattern, the aerodynamically curved pattern controllers produce a tight ceiling-hugging air pattern, even at low airflow rates.

The sloped plenum provides short horizontal throws and wide horizontal spreads, which is ideal for small spaces to reduce the chance of draft in the occupied zone.
