Abstract
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.
