Continuous-Duty Manufacturing
In 24/7 production lines, consistent filtration prevents unplanned downtime. This element's high collapse strength and bypass safeguard the system during peak demands, ensuring hydraulic oil remains free of damaging particles.
Dusty or High-Particulate Settings
In environments like quarries or steel mills, airborne contaminants can enter reservoirs. The 50 micron wire mesh captures debris before it damages seals and valves, extending component life.
Scheduled Maintenance Intervals
Planned replacements are straightforward with this drop-in element. Its industry-standard dimensions and direct interchange with multiple brands simplify servicing across your fleet.
Multi-Brand Fleet Management
If you operate hydraulic systems using Fai Filtri, Fleetguard-ST, Hydac, or Oxfil filters, stocking SPM-HYD-1851 consolidates inventory, reduces costs, and aligns with a price-beat guarantee.
SPM-HYD-1851 is a direct replacement for elements with cross-references from Fai Filtri, Fleetguard-ST, Hydac, and Oxfil. If your existing filter matches one of these brands and the dimensions (921 mm height, 143 mm outer diameter), it will fit. It is compatible with Hydac hydraulic equipment.
This element uses a wire mesh media with a filtration rating of 50 micron. Wire mesh is robust and cleanable in some cases, though as an aftermarket part it is typically replaced at service intervals.
The filter has a total height of 921 mm, an outer diameter of 143.5 mm, and inner diameters of 95.5-96.5 mm. It is a drop-in element with no thread; it seats directly into the filter housing. No special adapters are needed when replacing the specified cross-references.
SPM-HYD-1851 is built to match OEM specifications for fit, function, and performance. It is not a genuine branded part but offers equivalent protection at a lower cost, backed by a 30-day money-back guarantee and a price-beat guarantee.
Ensure the hydraulic system is depressurised and drained before opening the housing. Remove the old element, check the housing for debris, and insert SPM-HYD-1851 with the flow direction arrows pointing out-to-in. Replace the cover and refill fluid as per equipment manual.
We ship worldwide with tracking. Every SPM-HYD-1851 comes with a 30-day money-back guarantee and our price-beat guarantee. If you find a lower price on a comparable filter, we will match or beat it.
