An oxygen concentrator is utilized in combination with a compressor to provide a highly enriched and compressed oxygen gas in a mobile container such as a gas cylinder. The combination and method of production provides for the facile preparation of an enriched source of oxygen for use by an ambulatory or wheelchair-confined patient. The oxygen concentrator utilizes two or more molecular sieves to provide a breathable gas of from approximately 80 to about 98 percent oxygen from atmospheric air. The oxygen-enriched gas is stored in a concentrator product tank and can be prioritized so as to supply a patient with a proper amount and concentration of oxygen and secondarily to supply any surplus or excess enriched oxygen to a compressor. The compressor utilizes multiple stages to produce the highly compressed oxygen-enriched gas and utilizes a two-part piston at low rpm to enhance low wear and low noise. The multiple pistons of the compressor can either all rotate at one RPM or in an alternative embodiment, at least a first piston can rotate at a higher RPM than any remaining pistons. Desirably, at least the initial piston of the alternative embodiment is driven by one drive shaft source with one or more other remaining pistons being driven by a second drive shaft.

[ What is claimed is:] [1.]1. An apparatus for compressing and storing an oxygen-enriched gas, comprising;an oxygen concentrator product tank having enriched oxygen therein,a motor driven compressor operatively connected to said oxygen concentrator product tank to receive oxygen-enriched gas therefrom, said motor driven compressor operated independently of an oxygen concentrator power source and operated by a power source other than oxygen-enriched gas from said concentrator product tank, said motor driven compressor being capable of compressing said oxygen-enriched gas to a high pressure, said motor driven compressor containing a plurality of pistons, wherein a first piston is driven by a first drive shaft and a second piston is driven by a second drive shaft, anda high-pressure storage container operatively connected to said motor driven compressor for portable storage of said high-pressure oxygen-enriched gas,wherein said first piston is a wobble piston and wherein said second piston is a non-wobble piston, wherein said wobble piston compresses said gas from a first pressure to a second pressure and wherein said non-wobble piston compresses said gas from said second pressure to a third pressure.
