Abstract: The device of the current invention produces volumes of compressed air by utilizing a turbocharger, a compact combustion assembly, and a hydraulic power pack. The turbocharger includes a turbine and centrifugal compressor, each being interconnected using a pressure-lubricated bearing such that the turbine drives the compressor. Compressed air leaving the compressor is passed through a junction box containing a plurality of air distribution nozzles. The nozzles direct the compressed air either to a pressurized receptacle or back to the combustion assembly in order to provide a source of air for a combustion chamber. This device will economically obtain significant volumes of compressed air more efficiently than other known methods.
