ABSTRACT:
The apparatus of the present invention would relate to an air diffuser assembly which would comprise an aerator body having a plurality of side walls connected to form an enclosure and at least a pair of intersecting angularly oriented side walls forming an air container envelope for retaining an air volume therewithin. It would also have an air inlet adapted to convey air into said air body at the air container envelope, and a plurality of tear-shaped openings being provided in the body below the air container envelope allowing air to discharge air from the body through the tear-shaped openings, with each of the tear-shaped openings providing an upper pointed portion which would minimize the bubble size of air discharged through the openings. The apparatus would also comprise a baffle plate mounted within the enclosure at the air inlet, the baffle plate preventing the short circuit travel of air received by said enclosure to the tear-shaped openings placed on the body adjacent the air inlet. There would also be included an attachment means associated with the air inlet for attaching the aerator body to an air conveying conduit.
