Use cases & applications
Heavy-Duty Earthmoving
In demanding earthmoving applications, such as excavators and bulldozers, this filter handles high contaminant loads. The 25 µm inorganic microfibers maintain oil cleanliness, extending component life in dusty job sites.
Continuous-Duty Operations
For equipment running long shifts, consistent filtration is critical. This filter's robust media maintains flow while trapping particles, reducing unplanned downtime and maintenance intervals.
Fleet Maintenance Consolidation
Fleet operators with mixed Caterpillar and Komatsu machinery can standardize on this single filter. It simplifies inventory management and ensures uniform protection across different models.
Cold-Weather Hydraulic Systems
In cold climates, hydraulic oil viscosity increases. The filter's design allows adequate flow even when cold, preventing pressure drops and ensuring reliable system response during startup.
