Use cases & applications
High-Pressure Hydraulic Systems
In high-pressure hydraulic circuits, the wire mesh media withstands pressure spikes while capturing 25 µm particles, protecting pumps and valves from wear. This filter is ideal for continuous-duty applications where reliability is critical.
Mobile Equipment Hydraulics
For mobile machinery like excavators or loaders, the robust wire mesh construction resists vibration and cyclic loads. The out-in flow design simplifies installation in tight spaces, reducing downtime during field maintenance.
Industrial Hydraulic Power Units
In stationary power units, this filter handles high flow rates and maintains consistent filtration over long service intervals. The 25 µm rating balances protection and pressure drop, optimising system efficiency.
Retrofit and Cross-Reference Replacements
When replacing filters from multiple brands including Hydac, Stauff, or Mahle, this single part number consolidates inventory. Its dimensional compatibility ensures a direct swap without adapter modifications.
