IV. 3. Operating principle
The compressor sends filtered ambient air to a group of valves, which allows compressed air to
pass to the column in production. The columns contain a molecular sieve, whose function is to
adsorb the nitrogen and thus allow oxygen to pass. The oxygen is then directed to a pressure
reducing valve through the flow control valve to the oxygen outlet fitting.
During this time, the column which is being "regenerated" is connected to the ambient air and a
current of oxygen is passed through it (from the column "in production"). In this way, when one column
is in production, the other is in a nitrogen desorption or "regeneration" phase. The oxygen air finally
passes through a product filter situated prior to the oxygen therapy outlet.
