Trykluft Standard ISO 8573-2010
We use ISO 8573-2010 as a reference when choosing compressed air filters, and to find out to which level
it is necessary to clean the air. ISO 8563-2010 contains particles class, water class and oil class. When
refering to an ISO class, the classes are written in that order.
As an example: ISO class 2.4.1
