compressor output results in less air for the sieve beds. Therefore, the
production of oxygen decreases.
Since this drop in oxygen production occurs over a very long period of
time, there is no regular preventative maintenance required on the
compressor. In the event of degradation in the performance of the unit,
the compressor should be replaced.
Sound Level
The condition of the compressor's bearings mainly determines its sound
