High-Dust Environments
In mining, quarrying, or earthmoving applications where airborne dust is extreme, the 25-micron inorganic microfibre media captures harmful contaminants before they circulate through the engine. This extends oil life and protects critical components from abrasive wear, reducing unplanned downtime.
Continuous-Duty Operations
For equipment running around the clock, such as generator sets or pumping stations, consistent lubrication cleanliness is non-negotiable. This filter maintains filtration efficiency under steady high pressure, helping to avoid oil-related failures during extended service intervals.
Fleet Maintenance Consolidation
When servicing a mixed fleet that includes Caterpillar machinery, this filter consolidates spares inventory by covering multiple OEM part numbers. Maintenance teams can stock one reliable aftermarket filter instead of managing separate branded items, simplifying procurement and reducing carrying costs.
Scheduled Servicing Efficiency
Workshops performing routine oil changes on Caterpillar equipment benefit from batch installing this filter. Its standard dimensions and thread type allow quick, hassle-free replacement, helping meet tight maintenance windows while maintaining quality filtration.
This filter is a direct replacement for specific Caterpillar oil filters. Please compare the cross-reference numbers from Caterpillar, Fai Filtri, Mahle, Oxfil, Purolator, or SF Filter with your current filter to confirm compatibility. The thread type is UN 1.1/2 inch female bottom, outer diameter 137 mm, and total height 305 mm.
The filter uses inorganic microfibre media with a 25 micron rating. This design effectively removes contaminants while allowing adequate oil flow, supporting engine reliability under normal to heavy-duty operating conditions.
The thread is a UN 1.1/2 inch female type located at the bottom. The filter's total height is 305 mm and the outer diameter is 137 mm. Always verify these measurements match your filter housing before installation.
This is an aftermarket filter that is built to match the OEM specifications of the branded filters it replaces. It offers a cost-effective alternative without sacrificing compatibility, but it is not a genuine Caterpillar, Fai Filtri, Mahle, Oxfil, Purolator, or SF Filter part.
Installation follows standard spin-on oil filter procedures. Clean the mounting surface, apply a thin film of clean oil to the gasket, and spin the filter on until the gasket contacts. Then tighten to the manufacturer’s recommended torque. Always dispose of the old filter and oil responsibly.
