In one embodiment, the compressor includes a compressor housing and a power input shaft protruding from the compressor housing adjacent the air exhaust port. The silencer housing preferably includes a concave portion that at least partially receives the power input shaft. The silencer housing can also include a groove on the inner surface, and the resonator assembly can be at least partially positioned in the groove. Preferably, the resonator assembly includes a resonator plate, a plurality of resonator pipes extending through the plate, and a reinforcing flange coupled between at least two of the resonator pipes.
