Abstract

A desiccant tower receives air at its air inlet and concentrates the oxygen in this air in order to provide a gas at its gas outlet which has a concentration of oxygen exceeding the concentration of oxygen normally found in air. A bypass conduit is coupled to the desiccant tower so as to syphon off gas from the desiccant tower at a point where the gas within the desiccant tower has a concentration of oxygen which is less than the concentration of oxygen in the gas at the gas outlet of the desiccant tower. The gases at the gas outlet of the desiccant tank and in the conduit are mixed so as to produce an output gas mixture having a desired concentration of oxygen. The desired concentration of oxygen is less than a desiccant tower can ordinarily provide but greater than the concentration of oxygen normally found in air.
