Use cases & applications
High-Contaminant Environments
In dusty or debris-heavy settings, the 25 µm inorganic microfibre media traps fine particles effectively, holding more dirt before reaching capacity. This extends service intervals and shields pumps, valves, and bearings from abrasive wear.
Continuous-Duty Operations
For machinery running around the clock, the integrated bypass valve maintains oil flow even if the element clogs. This prevents pressure starvation and unplanned downtime, allowing maintenance to be scheduled without immediate risk of damage.
Fleet Maintenance Consolidation
Workshops handling diverse equipment can stock this single element, which cross-references multiple major filter brands. It simplifies inventory, reduces shelf space, and lowers procurement overhead while ensuring a quality replacement is always on hand.
Cold-Start Protection
During low-temperature starts, high oil viscosity can stress the filter. The 1.75 bar bypass valve opens to allow circulation without collapsing the element, protecting the system until the oil warms and flows normally.
Frequently asked questions
How do I confirm this filter fits my equipment?
Compare the filter's dimensions, total height 265 mm, outer diameter 130 mm, smallest inner diameter 64.5 mm, with your current element. Also check that the cross-referenced brand part numbers (Fai Filtri, Filtrec, Lha, Oxfil, Sofima) match your machine's specified filter.
What micron rating does this filter provide?
It uses inorganic microfibre media with an absolute filtration rating of 25 µm. This means it removes particles 25 microns and larger, delivering effective protection for hydraulic and lubrication system components.
What are the critical installation dimensions?
The element measures 265 mm in total height, 130 mm outer diameter, and has a smallest inner diameter of 64.5 mm. These dimensions ensure a drop-in fit for compatible housings where these values align.
Is this a genuine OEM filter?
No, it is an aftermarket replacement built to the original dimensions and ratings for form, fit, and function. It provides the same performance as branded equivalents at a lower cost, without the OEM premium.
How do I install this filter element?
This filter is a cartridge-style element. Open your filter housing, carefully remove the old element, clean the housing interior, insert the new element, and ensure all sealing faces are clean and correctly seated before reassembly.
