ABSTRACT:
An improved air diffuser or air boot has a unique incremental air dampering and air pattern control mechanism, namely a plurality of independent adjacent flat damper plates or blades which are adjustably attached to an inner surface of a bottom ledge just above an air outlet throat and are slideable across the throat. Each plate may be manually or automatically slid from its open position resting on the ledge to a closed position where it butts against the far side of the air outlet throat.
