Abstract
A compressor assembly having a housing with a number of sound control chambers. A method of controlling a sound level of a compressor assembly having a step of providing a plurality of sound control chambers. A method of controlling a sound level of a compressor assembly having a step of eliminating an operator's line-of-sight view to noise producing components of the compressor assembly. Sound level of a compressor can be controlled by separating the internal volume of a housing which encases at least a portion of a pump assembly to create sound control chambers and/or eliminating an operator's line-of-sight view to noise producing components of the compressor assembly.

A compressor assembly, comprising:
- a universal motor;
- a belt-driven pump assembly having a pump driven by a drive belt driven by the universal motor;
- a housing configured to cover at least in part each of an air ducting shroud, a conduit and a belt-driven pump assembly;
- a fan configured to provide a cooling air;
- said air ducting shroud surrounding at least a portion of the universal motor and configured to feed a first portion of said cooling air to cool at least a portion of said universal motor;
- and
- said conduit configured to feed a second portion of said cooling air to cool at least a portion of said belt-driven pump assembly.
A compressor assembly, comprising:
- a universal motor;
- a belt-driven pump assembly having a pump driven by a drive belt driven by the universal motor;
- a fan configured to provide cooling air to at least a portion of each of said universal motor and said belt-driven pump assembly;
- a housing that covers at least a portion of each of said motor and said belt-driven pump assembly;
- a sound control chamber at least in part containing said belt-driven pump assembly, said sound control chamber contained at least in part by said housing;
- a fan chamber at least in part containing said fan, said fan chamber contained at least in part by said housing;
- and
- a noise level which is 75 dBA or less when the compressor is in a compressing state.
