An apparatus for providing oxygen-enriched air at a first pressure and at a second pressure, the second pressure being greater than the first pressure. The apparatus comprises, in combination, a pressure swing adsorption system and a pressure intensifier. The pressure swing adsorption system for enriching the oxygen content of air has a pressure of at least the first pressure. The pressure swing adsorption system is adapted to provide oxygen-enriched air to a first outlet at the first pressure and to provide oxygen-enriched air to a pressure intensifier at the first pressure. The pressure intensifier pressurizes the oxygen-enriched air and provides the oxygen-enriched air to a second outlet at the second pressure.

[ We claim:] [1.] A method for providing oxygen-enriched air at a first pressure and at a second pressure, said second pressure being greater than the first pressure, said method comprising:feeding air to an air separation system;simultaneously providing oxygen-enriched air from said air separation

[ We claim:] [1.] A method for providing oxygen-enriched air at a first pressure and at a second pressure, said second pressure being greater than the first pressure, said method comprising:feeding air to an air separation system;simultaneously providing oxygen-enriched air from said air separation system to a first outlet at said first pressure and to a second outlet connected to a pressure intensifier at approximately said first pressure;increasing the pressure of said oxygen-enriched air provided by the pressure intensifier to said second pressure;wherein said air separation system is capable of simultaneously providing oxygen-enriched air to said first outlet and said second outlet such that a flow of oxygen-enriched air can be supplied continuously to said first inlet while said pressure intensifier is pressurizing said oxygen-enriched air to said second pressure.
