Problems caused by poor
air or gas quality can cause
premature equipment failure
and unplanned shutdowns.
Filtering instrument air
and gas prevents these
problems, but having a
filter set at the compressor
may not be adequate.
Particulates, water and oil in the stream of
instrument air or instrument gas can wreak
havoc with downstream equipment. Here
are just a few examples. Approximately
90 percent of solenoid valves failures are
caused by particulate contamination. Oil
contamination can cause positioners to
fail due to hydraulic lock between the
spool and sleeve. Moisture and oil vapour
degrade pump seal materials. If oil reaches
the dryer media it will cause immediate
and complete failure. In addition, oil
or water can cause incorrect readings
from analytical equipment. Any of these
or other failures caused by inadequate
filtration can result in costly and time
-consuming maintenance and possible
unplanned shutdown. The costs related
to these failures can accumulate into
thousands or even millions of dollars.
Why point-of-use
filtration?
