Use cases & applications
Heavy-Duty Construction Sites
In dusty construction environments, the 12 µm microfibre media captures abrasive particles that could cause premature wear. This filter helps maintain oil cleanliness during long operating hours between service intervals.
Continuous-Duty Agricultural Operations
For tractors and harvesters running extended shifts, consistent filtration is critical. This filter delivers stable performance under high flow and temperature conditions, reducing the risk of engine damage.
Fleet Maintenance Consolidation
Workshop managers servicing mixed fleets of Ammann and Liebherr equipment can standardise on this single filter, simplifying inventory management and reducing the chance of fitting the wrong part.
Remote or Harsh Environments
In off-grid mining or forestry operations where replacement parts are hard to source, the robust construction of this filter ensures reliable oil filtration even when service intervals are extended.
