PCT No. PCT/AU96/00129 Sec. 371 Date Sep. 10, 1997 Sec. 102(e) Date Sep. 10, 1997 PCT Filed Mar. 11, 1996 PCT Pub. No. WO96/28697 PCT Pub. Date Sep. 19, 1996This invention relates to an induction air handling unit of the type that uses a primary air flow to induce flow of secondary air through the air handling unit. It comprises an induction chamber (2) having an air flow entrance (22) and an air flow exit (23) and a nozzle (10) having an outlet (12) located within the induction chamber (20). The nozzle (10) is connected to a primary air flow that causes a secondary air flow to be induced through the induction chamber (20) via the entrance (22) and the exit (23). The nozzle (10) is characterized by the edge (12) forming an outlet that is of a scalloped shape. This has a dramatic effect on producing noise output from the nozzle (10).
