ABSTRACT:
A reaction-type fan has a housing with a central collar rotatably supporting a hub having blades extending radially therefrom. Nozzles are carried at the tip portions of the blades. Compressed air is directed through the housing, collar, hub and blades to the nozzles. The nozzles are arranged such that the reactive force of the compressed air exiting therefrom rotates the blades, thereby causing ambient gases to be drawn through the housing. Sound absorbing elements are positioned along the flow path of the compressed air to attenuate noise associated therewith.
