Abstract
A cross-over valve (24) alternately supplies compressed air from a source of compressed air (A) to a pair of beds (26, 28) filled with a molecular sieve material. An oxygen rich gas component separated from the compressed air by the molecular sieve beds is channeled to a separated gas reservoir (C). To use the oxygen in the reservoir, the compressed air is directed against a barrier, such as bellows (52), located within the separated gas reservoir to compress the oxygen rich gas component held therein. The oxygen rich gas component is then supplied at this elevated pressure to welding or other downstream equipment. In this manner, the oxygen separator may operate sixteen hours to provide a supply of oxygen for an eight hour shift. The oxygen is supplied to the downstream equipment at a higher pressure which is increased over and above the supply pressure from the oxygen separation device.
