An oxygen concentrator system with altitude compensation includes at least one oxygen concentrator sub-system and a plenum subsystem. The at least one oxygen concentrator sub-system produces oxygen enriched product which is outputted to both the oxygen concentrator system output and to a plenum chamber within the plenum subsystem. The plenum chamber is trickle charged with the oxygen enriched product when the at least one oxygen concentrator sub-system produces an excess amount of oxygen enriched product. Should the demand for oxygen enriched product exceed the capability of the at least one oxygen concentrator sub-system, additional oxygen enriched product is provided by the plenum chamber until such time that the capability of the at least one oxygen concentrator sub-system exceeds the demand for oxygen enriched product. At that time, oxygen enriched product is no longer provided by the plenum chamber but rather the plenum chamber is again trickle charged. A monitor/controller having an absolute pressure transducer controls the cycle times of the oxygen concentrator subsystem in accordance with an ambient barometric pressure measured by the absolute pressure transducer.
