Continuous-Duty Hydraulic Systems
In production machinery that runs around the clock, the 12-micron inorganic microfibre media delivers long service life by holding a high volume of contaminants. This reduces the frequency of filter changes and keeps your hydraulic fluid cleaner for longer, lowering overall maintenance costs.
Mobile Equipment in Dusty Environments
For loaders, excavators and agricultural machinery working in dirt and debris, the out-to-in flow design effectively captures airborne particles that enter hydraulic reservoirs. The robust media withstands variable flow conditions, protecting critical components from premature failure.
Preventive Maintenance Scheduling
Consolidating filter replacements across multiple machines is simpler when you use one reliable aftermarket part number. Keeping an inventory of SPM-HYD-1639 filters ensures quick servicing without the lead times and higher prices of branded equivalents.
High-Pressure Industrial Presses
Accurate control of clamping and forming forces depends on clean hydraulic fluid. The tight 12-micron filtration prevents silt and varnish from building up, which could otherwise cause valve spools to stick and lead to costly downtime.
The SPM-HYD-1639 is a direct replacement for compatible Fai Filtri, Fleetguard, Oxfil, Pall and ST Separat Tech elements. Verify the total height (337 mm), largest outer diameter (78 mm) and largest inner diameter (43.4 mm) against your current housing to ensure a proper fit.
This filter uses inorganic microfibre media with a 12-micron rating. It captures particles as small as 12 microns, which is comparable to the performance of the original elements it replaces.
The filter element has a total height of 337 mm, largest outer diameter of 78 mm and largest inner diameter of 43.4 mm. It is a drop-in element and does not feature threaded connections; it seats inside compatible housings that accept these dimensions.
SPM filters are built to match OEM specifications for fit, form and function. You get equivalent performance and reliability at a lower cost, without the brand premium. This particular element replaces filters from multiple well-known manufacturers.
Installation follows the standard procedure for your hydraulic filter housing. Depressurise the system, remove the old element, clean the housing, and insert the new SPM-HYD-1639. Always follow your equipment manufacturer's safety guidelines.
