ABSTRACT:
A pair of guide plates or deflectors are secured adjacent the exit of a discharge nozzle body. The body includes a circular inlet portion converging to a flattened, rectangular passageway. The guide plates are secured adjacent the exit of the flattened passageway. As air flow exits from the flattened passageway, the guide plates constrain the flow's natural expansion to the forward and lateral directions only, thereby creating a wide cleaning swath.
