High-Debris Environments
Operating earthmoving or agricultural equipment in dusty conditions puts extra strain on oil filters. The 25 µm media efficiently traps airborne dirt that enters the crankcase, helping to extend engine life and maintain consistent oil pressure even under heavy soiling.
Continuous-Duty Machinery
For generators, compressors, or pumps running around the clock, unscheduled downtime is costly. This filter’s robust construction, with an element collapse pressure of 5 bar and a 1.75 bar bypass valve, ensures reliable oil flow during extended service intervals, reducing the risk of stoppages.
Fleet Maintenance Programmes
Workshops servicing mixed fleets can standardise on this filter where the cross-reference matches, simplifying inventory and reducing confusion. The consistent 305 mm height and UN 1.1/2 inch thread make it straightforward to stock and deploy across multiple assets.
Cost-Sensitive Refurbishment
When rebuilding engines or performing major services, using aftermarket filters helps control project costs. This filter provides the same form, fit, and media specification as branded alternatives, enabling quality overhauls without overspending on consumables.
Verify that your current filter cross-references with Fai Filtri, Mahle, Oxfil, or Purolator elements. Also check that the mounting dimensions match: UN 1.1/2 inch female bottom thread, a total height of 305 mm, and an outer diameter of 137 mm. If these align with your existing part, this filter is a correct fit.
It uses impregnated paper media with a nominal rating of 25 µm. This means it captures most particles larger than 25 microns, balancing effective contaminant removal with adequate oil flow for heavy-duty applications.
The filter has a female UN thread measuring 1.1/2 inches, located on the bottom. Overall height is 305 mm and the outer diameter is 137 mm. The element collapse pressure is rated at 5 bar, and the bypass valve opens at 1.75 bar.
It is a direct aftermarket replacement built to match OEM specifications for fit and media efficiency. While it is not a genuine OEM product, it delivers dependable performance under normal operating conditions and is backed by our guarantees.
Clean the engine’s mounting flange and apply a thin film of clean oil to the new filter’s gasket. Spin the filter on by hand until the gasket contacts the base, then hand-tighten according to the maker’s recommendation, typically a further three-quarter turn. Avoid using tools, as overtightening can damage the seal or canister.
