3.2 Specific remarks
QMF filter
The filter should be preceded by a water separator if no water separator is integrated in the after cooler of
the compressor. In case a dryer is preceding the filter, a water separator is no longer required.
QPF filter
It is recommended to install a grade QMF filter upstream the QPF filter. If not, the load on the QPF filter
element may become too high and will reduce its lifetime.
QCF filter
When the QCF filter is used with an adsorption type air dryer, install the filter downstream of the dryer.
QAF filter
To protect the active carbon element, a QAF filter must always be preceded by a QMF and QPF filter.
The filter should be mounted as close as possible to the point of use of the air.
3.3 ISO 8573-1:2010
General
For new installations as well as for installations that have to be made up-to-date, the ISO 8573-1:2010
standard can be used. Some proposals are given fulfilling this standard.
This part specifies purity classes of compressed air with respect to particles, water and oil, independent of
the location in the compressed air system at which the air is specified or measured, for ISO 8573-1:2010
standard.
The ISO 8573-1:2010 standard only concerns compressed air for general use and does
not deal with, or is not applicable to, e.g. breathing air.
