6.2 Cleaning of filter elements
The filter elements are passed through from outside to inside by the fluid, so the dirt accumu-
lates on the outside of the wire mesh.
Filter elements clogged with dirt particles must be rinsed in uncontaminated cleaning fluid.
When cleaning manually, close the open end of the filter element in oder to prevent a carry-
over of dissolved dirt particles from the dirt side (outside) to the clean side (inside).
●
For effective manual cleaning, we recommend a special cleaning tool (rotating noz-
zle) which flushes the element from inside to outside with cleaning fluid.
●
To clean the filter element without any special tools, first soak the element extensively
in cleaning fluid until incrustations get soft. Subsequently, blow clean, pressurised air
from inside to outside.
●
Nearly fully automated and reliable cleaning is possible with dedicated cleaning units.
Choice of the appropriate detergent depends on the kind of liquid to be filtered. Petroleum
ether (benzine) is suitable for lubricating oil. Specialised detergents as well as equipment for
cleaning of metallic filters can be obtained from Friedrichs Filtersysteme GmbH.
