Continuous-Duty Operation
For equipment that runs extended hours, this filter's 10 bar collapse pressure ensures it maintains integrity under sustained high-pressure conditions, reducing the risk of bypass or rupture.
Cold-Start Protection
The bypass valve opens at 1.75 bar, allowing oil to circulate quickly during cold starts when oil is thick, preventing engine starvation until the filter media warms up.
Fine Filtration for Sensitive Hydraulics
The 10 µm impregnated paper media captures fine contaminants that can wear out hydraulic components, extending the life of pumps and valves in Wacker machinery.
Inventory Consolidation
This single aftermarket filter replaces multiple brand cross-references (Airfil, Fai Filtri, Oxfil, Steimbock, Wacker), simplifying stock management for workshops servicing various equipment.
Check your equipment's manual or the existing filter's part number. Our SPM-OIL-1170 cross-references Airfil, Fai Filtri, Oxfil, Steimbock, and Wacker filters. If your current filter matches any of those brands, it is a direct replacement.
This filter uses impregnated paper media with a filtration rating of 10 µm. This means it captures particles as small as 10 microns, providing effective protection for your engine or hydraulic system.
The total height is 135 mm, outer diameter is 62.5 mm, and smallest inner diameter is 28.6 mm. Thread size is not specified in the provided data, so please verify compatibility with your filter head.
No, this is an aftermarket replacement built to match OEM specifications. It is not a genuine Wacker part but is designed to fit and function as a direct replacement for the listed brands.
