ABSTRACT:
A diffuser is disclosed incorporating a plenum chamber adapted for mounting upon the T bars utilized to support ceiling tile in a suspended ceiling structure. The plenum chamber includes an elongated opening along the bottom thereof to permit conditioned air to escape from the plenum into the room below. A pattern controller is mounted in the plenum and includes a longitudinally extending sheet having a continuously curved surface extending from one edge of the opening upwardly into the plenum to adjustably partially block the flow of air through the opening. The portion of the sheet adjacent the edge of the plenum is offset to lower the exit surface of the sheet so that the curved surface extends downwardly to or below the surface of the ceiling.
