Use cases & applications
High-Contamination Environments
In dusty construction or mining sites, airborne particles accelerate hydraulic fluid contamination. The 5-micron inorganic microfibre media captures fine debris effectively, protecting pumps and valves from abrasive wear and reducing unplanned downtime.
Continuous 24/7 Operation
For machinery running around the clock, filtration reliability is paramount. With a 20 bar collapse pressure, this element maintains consistent flow and particle removal under sustained use, helping avoid costly interruptions in production.
Preventive Maintenance Scheduling
Scheduled filter changes keep hydraulic systems at peak cleanliness. Keeping this filter on hand simplifies interval servicing, eliminating the need to source multiple OEM part numbers and ensuring timely replacements.
Fleet Standardisation
Operations using Hydac, Vickers, and other compatible equipment can consolidate filter inventory with this single element. It cross-references across several major brands, reducing stock complexity and procurement costs.
Frequently asked questions
How do I confirm this filter will fit my equipment?
This element directly replaces Hydac filters with a largest outer diameter of 93 mm, largest inner diameter of 48.3 mm, and total height of 162 mm. It also cross-references to equivalent aftermarket references from Fai Filtri, Hy-Pro, Oxfil, Triboguard, and Vickers. Always check your housing dimensions against these specifications before ordering.
What is the filtration rating and media type?
The filter uses inorganic microfibre media rated at 5 microns. This media offers high dirt-holding capacity and consistent particle capture, which is critical for extending the service life of hydraulic pumps, motors, and valves.
Does this element have threads, and what are the key dimensions?
No, this filter is a drop-in cartridge without threads. The key measurements are: largest outer diameter 93 mm, largest inner diameter 48.3 mm, and total height 162 mm. Confirm that your filter housing matches these values to ensure correct sealing and bypass operation.
Is this an original OEM part?
