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-enriched air 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 enriched air 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 enriched air finally passes through a product filter situated prior to the oxygen therapy outlet.
