A sealed compressor assembly includes a compressor pump driven by a motor
mounted within a sealed housing. The sealed housing comprises a center
shell extending between first and second ends and a lower shell attached
to the center shell. The lower shell is generally square shaped with
mounting feet extending diagonally from each corner. The lower shell
includes a predetermined amount of material removed to shift the resonance
frequency of the sealed housing outside the operating frequency range of
the motor and compressor.
