ontaminated compressed air
in service units causes faster
wearing of seals, oiled-up valves
in the control section and dirty
silencers. This decreases the availability
of the machines and the service life of
the pneumatic components and systems,
and increases the energy costs due to
leakage and the maintenance required.
Standard air quality classes with ISO
The topic of compressed air quality
gained a new and official status in 2010
with ISO 8573, a series of international
standards designed to ensure the purity
of compressed air. The standard 8573-1
defines the maximum permissible
contaminant content for the respective
compressed air quality classes.
Fresh air
standards
Compressed air preparation is not exactly
a hot topic for
plant operators. Yet poor compressed air quality causes
wear to high-quality pneumatic valves and drives and also
reduces machine availability. Now a new ISO standard is
putting the topic of compressed air preparation back on
the agenda. So for help in selecting service units to achieve
the right compressed air quality class, look no further than
Festo.
New compressed air quality classes
“If you want to
increase your machine
availability, you need
to go right back to
the beginning and
take a close look at
your compressed
air supply.”
