Abstract
Apparatus and methods of supplying a highly enriched oxygen gas steam on board an aircraft. The gas stream is generated by an oxygen concentrator which concentrates atmospheric air by using at least one adsorber. The adsorber is made of a faujasite zeolite and has a Si/Al ratio between 1 and 1.5. The faujasite zeolite is also exchanged with silver by about 10%. Once generated, the gas stream is supplied to the airways of a person onboard an aircraft.
