<div class="moz-cite-prefix">The compressor has been working
continously for a couple of years, have you ever serviced it?</div>
<div class="moz-cite-prefix">If not plan a service as soon as
possible, maybe a clean filter or something else is needed.</div>
<div class="moz-cite-prefix">Looking at the attached plots it seems
it is working at 50% of its setpoint pressure and never stops, it
sounds like there is a loss of efficiency in the device.</div>

<pre class="moz-quote-pre" wrap="">Hi Brian,
I also noticed that the compressor changed the behavior during the last year.
Take a look to the attached plots. In April 2018 the frequency of oscillations is different from October 2018. The time range is 8 hours, one shift.
In April 2019 the compressor is working all the time.
Regards,
Valery
