A method for delivering at least two working gases from a common air supply comprising the steps of depleting the air in O.sub.2 in order to obtain a first gas mixture having an O.sub.2 content less than or equal to t1; delivering at least a portion of this first gas mixture as a first working gas;

A method for delivering at least two working gases from a common air supply comprising the steps of depleting the air in O.sub.2 in order to obtain a first gas mixture having an O.sub.2 content less than or equal to t1; delivering at least a portion of this first gas mixture as a first working gas; depleting another portion of this first gas mixture in O.sub.2 in order to obtain the second gas mixture having an O.sub.2 content less than or equal to t2, wherein t1 is greater than t2; and delivering the second gas mixture as a second working gas.
