The oxygen enricher apparatus provides a circuitous path for the flow of air to effect a reduction in noise while also using the oxygen-depleted air flow to cool the vacuum pump which draws the oxygen-enriched air flow through the membrane cells. The oxygen-enriched air flow is also passed through a condensor in heat exchange relation with the incoming air flow. Water which is separated from the oxygen-enriched air flow is wicked to an evaporator pad in the warm exhaust flow of the oxygen-depleted air flow.

In an apparatus for providing air enriched with oxygen, said apparatus having an array of selectively permeable membrane cells, said cells being adapted to permit oxygen to permeate to an interior cavity thereof at a greater rate than nitrogen to form a flow of oxygen-enriched air in said interior cavity; means for developing a flow of atmospheric air across said array; conduit means through which air enriched with oxygen is drawn off from said interior cavity of said cells; a partial vacuum maintaining means interconnected with said conduit means to draw the oxygen-enriched air through said conduit means; the improvement comprising: a membrane stack box enclosing said array and having an inlet port for flow of atmospheric air and an outlet port in a non-planar orthogonal displaced relationship to said inlet port for a flow of nitrogen enriched air whereby virtually the entire flow of air is directed through said membrane stack box in a manner to achieve noise suppression; a cabinet core comprising a housing structure for said partial vacuum maintaining means, said housing structure having an inlet slot communicating with said outlet port of said membrane stack box to receive the flow of nitrogen-enriched air and an outlet slot in non-planar orthogonal displaced relationship to said inlet slot to exhaust the flow of nitrogen enriched air; and a cabinet forming together with said membrane stack box and said cabinet core an atmospheric air inlet duct in communication with said membrane stack box inlet port and an air exhaust duct in communication with said housing structure outlet slot.
