Use cases & applications
High-Pressure Hydraulic Systems
Ideal for systems operating at high pressures up to 210 bar, where element collapse resistance is critical. The wire mesh media ensures consistent filtration without bypass, protecting sensitive components like pumps and valves.
Continuous-Duty Industrial Applications
Suitable for machinery running 24/7, such as presses or injection moulding machines. The robust construction and high collapse pressure reduce the risk of element failure during extended operation.
Fluid Cleanliness Maintenance
Effective for maintaining ISO cleanliness codes in hydraulic circuits where 25 µm filtration is required. The wire mesh media is cleanable and reusable, lowering long-term consumable costs.
Retrofit and Replacement Schedules
A direct drop-in replacement for multiple brands, simplifying inventory management. Facilities with mixed fleets can stock one element for various equipment, reducing downtime.
Frequently asked questions
How do I confirm this filter fits my equipment?
Check your existing filter's dimensions: total height 257 mm, largest inner diameter 47.5 mm, largest outer diameter 83.5 mm. This element is a direct replacement for Fai Filtri, Hydac, Internormen, Mahle, Oxfil, ST Separat Tech, and Stauff units. If your part cross-references one of these brands, it will fit.
What is the filtration rating and media type?
This element uses wire mesh media with a filtration rating of 25 µm. Wire mesh is cleanable and offers high dirt-holding capacity for hydraulic systems.
What are the thread and dimensional specifications?
The element has an out-to-in flow direction. Dimensions: total height 257 mm, largest inner diameter 47.5 mm, largest outer diameter 83.5 mm. It does not include threads; it is a cartridge-style element that seals with O-rings (not included).
Is this element genuine or OEM?
This is an aftermarket replacement built to the original dimensions and ratings. It is not genuine or OEM but is designed to perform equivalently to the original parts from brands like Hydac and Mahle.
How do I install this filter element?
Installation is straightforward: remove the old element, clean the housing, lubricate the O-rings (if applicable), insert the new element with flow direction out-to-in, and tighten the housing cap. No special tools are required.
