Filtering: functional principles & basics
Filtering processes separate or clean substances. Only dirt with a certain particle size measured in micrometres is allowed to pass through the filter. The interaction between genuine filter elements and lubricants from the WIRTGEN GROUP prevents damage caused by contamination and, at the same time, increases machine utilisation rates.
The high-quality promise of Wirtgen Group filter systems
Particularly in the case of construction machines that work continuously under heavy loads, the filters used must be perfectly matched to the relevant construction site requirements, i.e. appropriately designed. Although fitting WIRTGEN GROUP machines with non-OEM parts appears, on the face of it, to be cheaper, experience has shown that this often leads to considerable complications, e.g.:
Poorer cleanliness classes
Reduced component protection
Shortened service life of machine components
Compromised operational reliability (machine standstill)
Reduced utilisation rates
Increased life cycle costs
In the case of all filter types, it is not only the dirt holding capacity that is decisive, but also the resulting pressure differences. In the case of non-OEM products, this may lead to an increase in the number of blockages as the degree of contamination increases.
