Abstract:
An oxygen concentration system for providing oxygen enriched gas to an end user comprising:a first oxygen concentrating device comprising: a pressurized air source that provides a first flow of pressurized air derived from an ambient environment, the pressurized air source having a first pressurized air outlet, a first primary gas fractionalization element operatively coupled to the first pressurized air outlet to receive the first flow of pressurized air from the pressurized air source, the first primary gas fractionalization element providing a first flow of oxygen enriched gas and having a first oxygen enriched gas outlet, a product tank operatively coupled to the first primary gas fractionalization element to receive the first flow of oxygen enriched gas from the first oxygen enriched gas outlet, and a valve operatively coupled to the product tank to regulate delivery of the oxygen enriched gas from the product tank to an end user; a supplemental oxygen concentrating device including a first supplemental gas fractionalization element for providing a second flow of oxygen enriched gas, the first supplemental gas fractionalization element having a second oxygen enriched gas outlet; and a first pneumatic interface operatively coupled to the supplemental oxygen concentrating device so as to receive the second flow of oxygen enriched gas from the second oxygen enriched gas outlet and to communicate the second flow of oxygen enriched gas to the product tank.
