Use cases & applications
Dusty Worksites
On construction, mining or agricultural sites, airborne dust constantly enters hydraulic reservoirs. The 7 µm inorganic microfibre media captures fine particles before they circulate, protecting pumps and cylinders from abrasive wear and extending service life in gritty conditions.
Continuous-Duty Equipment
Machines that operate non-stop, such as injection moulding presses or power generation units, demand consistent oil cleanliness. This filter's high dirt-holding capacity sustains hydraulic fluid quality over long runs, reducing the risk of unplanned outages caused by valve sticking or pump cavitation.
Multi-Brand Fleet Consolidation
Maintenance teams managing diverse Hydac-equipped machinery often juggle multiple filter part numbers. One this filter replaces numerous cross-referenced brands, streamlining inventory and ensuring a proven filter is always on hand for quick turnarounds.
Preventive Maintenance Routine
Scheduled filter changes are essential for hydraulic reliability. With its drop-in dimensions matching the original, this filter makes replacements fast and error-free, so your crew can complete servicing on time and keep the equipment running according to plan.
