Compressed air quality classes
to DIN ISO 8573-1
There are recommended compressed air quality classes for the different pneumatic applications to ensure trouble free function of equipment. In the table opposite the compressed air quality for each type of contamination is listed separately. The quality classes are recommended in DIN ISO 8573-1.
Guide values for applications
Through use of the appropriate compressed air quality class, compressed air preparation can be optimised and equipment downtime and higher maintenance costs avoided.
