Use cases & applications
Continuous-Duty Hydraulic Systems
In systems running 24/7, the wire mesh media offers low flow resistance and high dirt-holding capacity, reducing the frequency of element changes and minimising downtime.
High-Vibration Environments
The robust construction of the wire mesh withstands mechanical stress from pumps and motors, maintaining filtration integrity even under constant vibration.
Cold-Start Conditions
Wire mesh media does not absorb moisture or swell, ensuring consistent filtration performance during cold starts when oil viscosity is high.
Inventory Consolidation
Cross-referencing multiple brands means one part number can replace filters from Fai Filtri, Internormen, Mahle, Oxfil, ST Separat Tech, Stauff, and Woodgate, simplifying stock management.
