ABSTRACT:
An explosion proof compressor and method for explosion proofing a compressor for use with air conditioning or refrigeration system in a hazardous location where flammable gases or vapors may exist places the electrical supply terminals for the compressor within a gas tight housing which is pressurized with low pressure refrigerant gas being compressed by the compressor. The gas tight housing is in a fluid-transmitting relationship with a pressure responsive switch, whereby upon a pre-selected decrease in the pressure within the gas tight housing, the pressure responsive switch terminates the supply of electrical power to the compressor motor.
