ABSTRACT:
A sound reduction unit for a compressor, in which the compressor has a cooling fan and an air intake, and the sound reduction unit includes a housing forming an enclosure about the air inlet and a plurality of sound absorbing baffles disposed in the housing and blocking any direct passage of air into the air inlet. The baffles provide free flow of air, which may be achieved by staggering the baffles in overlapping angular rows in a generally rectangular housing, but which preferably includes allowing a gap between the noise reduction unit and the cooling fan, with a flange baffle extending from the noise reduction unit beyond the cooling fan.
