Use cases & applications
Continuous-Duty Hydraulic Systems
In applications where hydraulic equipment runs for extended periods, the 25 µm inorganic microfibers media captures fine particles that cause wear and tear. This filter helps maintain fluid cleanliness, reducing the risk of component failure and extending maintenance intervals.
Mobile Equipment in Dusty Environments
For mobile machinery operating in dusty conditions, the out-in flow design prevents contaminants from entering the system. The robust media ensures consistent filtration even under varying flow rates, protecting sensitive hydraulic components.
Inventory Consolidation for Multi-Machine Fleets
Fleet operators using Hydac-equipped machinery can standardize on this single filter part number, simplifying stock management and reducing the risk of using incorrect filters. This streamlines maintenance logistics and cuts downtime.
High-Pressure Hydraulic Circuits
In circuits with high operating pressures, the filter's construction withstands demanding conditions. The 25 µm rating balances efficiency and flow capacity, ensuring adequate protection without excessive pressure drop.
