Use cases & applications
High-Contamination Environments
In applications where hydraulic systems are exposed to dust, dirt, or metal particles, the 5 µm inorganic microfibers media captures fine contaminants, reducing wear on pumps and valves. This extends component life and minimizes unplanned downtime.
Continuous-Duty Operations
For machinery running 24/7, such as in manufacturing or mining, this filter maintains oil cleanliness over extended periods. Its robust construction supports consistent flow rates, ensuring system efficiency without frequent replacements.
Fleet Maintenance Simplification
When managing multiple machines from brands like Hydac, this single filter cross-references numerous OEM part numbers, allowing you to stock one part for various equipment. This reduces inventory complexity and simplifies maintenance routines.
Hydraulic System Retrofits
Upgrading older hydraulic systems with modern filtration is straightforward with this aftermarket filter. Its dimensions match common filter housings, enabling easy installation without modifications.
