Claim 16:
17. A gas concentrating system comprising:
a plurality of sieve beds;
an oxygen sensor;
a pressure sensor;
a controller comprising:
logic collecting oxygen and pressure data;
logic calculating linear regressions for the oxygen and pressure data;
logic determining a first predicted time to failure for one or more gas concentrator components based on the oxygen linear regression calculation and a predetermined threshold oxygen purity level;
logic determining a second predicted time to failure for one or more gas concentrator components based on the pressure linear regression calculation and a predetermined threshold pressure level;
logic comparing the first and second predicted times to failure;
logic setting a time window based on the comparison; and
logic for generating one or more component alarms when the system is within the time window.
