Use cases & applications
High-Pressure Hydraulic Systems
In systems operating at high pressures up to 210 bar, this filter element maintains structural integrity under collapse pressure, ensuring continuous filtration without bypass. It is ideal for mobile and industrial equipment where pressure spikes occur.
Continuous-Duty Operations
For machinery running 24/7, the wire mesh media provides consistent filtration with low pressure drop, reducing the need for frequent replacements. This minimises downtime and maintenance intervals.
Retrofit Replacements
When upgrading or servicing older hydraulic units, this element directly replaces multiple brand cross-references, simplifying inventory management. It fits existing housings without modifications.
Dusty and Harsh Environments
The robust wire mesh construction resists damage from particulate ingress in dirty conditions, such as construction or mining sites. It protects downstream components from wear.
Frequently asked questions
How do I confirm this filter fits my hydraulic system?
Check your current filter's dimensions: total height 373 mm, largest inner diameter 47.5 mm, largest outer diameter 83.5 mm, and flow direction out-in. If these match, it is a direct replacement. Cross-reference your brand with Airfil, Fai Filtri, Internormen, Mahle, Oxfil, ST Separat Tech, or Stauff.
What is the filtration rating and media type?
This filter uses wire mesh media with a filtration rating of 60 µm. It is suitable for removing coarse particles from hydraulic fluids, protecting pumps and valves.
What are the exact dimensions and thread details?
The element has a total height of 373 mm, largest inner diameter of 47.5 mm, and largest outer diameter of 83.5 mm. No thread specifications are provided; it is a cartridge-style element that fits into a housing.
Is this an OEM or aftermarket part? How does it compare?
This is an aftermarket replacement built to the original dimensions and ratings from brands like Mahle and Stauff. It offers the same performance at a lower cost, but it is not a genuine OEM product.
How do I install this filter element?
