Abstract
An apparatus for producing an oxygen enriched gas having a compressor for supplying air under pressure, a unit for producing a gas enriched with oxygen from the air supplied from the compressor, a gas storage tank for reserving the oxygen enriched gas produced from the producing unit, a flow rate setting unit to set a flow rate of the oxygen enriched gas delivered from the gas storage tank, and a regulating unit for adjustably regulating an oxygen concentration of the oxygen enriched gas in response to a change in a requirement of an oxygen concentration of the oxygen enriched gas obtained at an outlet of the apparatus.
