Product Manual

Process piping recommendations
To reach class 1 for solid particles according to ISO8573-1, it’s recommended to use stainless
steel piping or AIRnet aluminum piping. Other types of piping, like brass or copper piping’s are
not recommended as the surface roughness is too high, which makes class 1 difficult to reach.
inPASS™ filter
When installing the filter with inPASS™, it is important that this inPASS™ is completely turned in
filter mode.
Refer to section inPASS™ instructions for more information on how to use the inPASS™
correctly.
3.2 Specific remarks
DD+ 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.
PD+ filter
It is recommended to install a DD+ filter upstream the PD+ filter. If not, the load on the PD+ filter
element may become too high and will reduce its lifetime.
DDp+ and PDp+ filter
When the DDp+ and PDp+ filters are used with an adsorption type air dryer, install the filter
downstream of the dryer.
UD+ 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.
QD+ filter
To protect the active carbon element, a QD+ filter must always be preceded by a DD+ and PD+
or UD+ filter.
The filter should be mounted as close as possible to the point of use of the air.
3.3 Smart service indicator
Commissioning
When installing the filter, the smart service indicator needs to be set up correctly according to the
filter grade:
