Continuous-Duty Manufacturing
In production lines running 24/7, the SPM-HYD-1821 keeps hydraulic oil clean to reduce wear on pumps and valves. Its high dirt-holding capacity minimises unplanned downtime, helping to sustain throughput and lower per-part costs.
Harsh Environment Operations
Equipment exposed to dust, moisture, or heavy vibration demands reliable filtration. The inorganic microfiber media resists degradation and maintains a consistent 25-micron barrier, protecting sensitive hydraulics in construction, mining, or agricultural machinery.
Scheduled Fleet Maintenance
For workshops managing multiple Hydac-equipped machines, this filter enables predictable change intervals. The aftermarket pricing cuts life-cycle costs, and planning bulk replacements becomes straightforward with one compatible element across many legacy systems.
Multi-Brand Inventory Consolidation
Because SPM-HYD-1821 crosses dozens of brand part numbers, from Donaldson to Pall to Mann-Filter, service centres can stock a single aftermarket filter. This simplifies ordering, reduces shelf space, and still guarantees fit for Hydac housings.
Check your existing filter’s dimensions against the SPM-HYD-1821: total height 483 mm, outer diameter 143 mm, largest inner diameter 96.5 mm, and smallest inner diameter 65.5 mm. As long as these match your housing, the filter will fit. There are no special mounting requirements beyond correct sizing.
It delivers a 25-micron absolute rating using inorganic microfiber media. This material traps hard particles like silt and wear debris while allowing clean oil to flow. The out-to-in flow path maximises contaminant capture without excessive pressure drop, keeping hydraulic systems operating within clean tolerances.
The SPM-HYD-1821 is engineered to match the critical internal diameters, largest ID 96.5 mm and smallest ID 65.5 mm, that locate on the filter head and seal. There are no threaded connections; the element drops into standard Hydac housings. Always compare your old element’s IDs to these specifications.
No, it is an aftermarket filter element built to mirror OEM dimensions and media performance. It provides equivalent contaminant control at a significantly lower cost. This makes it an attractive choice for cost reduction without sacrificing reliability.
Relieve system pressure, remove the housing cover, and take out the old filter. Clean the housing interior and verify the bypass valve moves freely. Insert the new SPM-HYD-1821 ensuring the flow direction (out-in) is correct, then reassemble. It is a simple drop-in replacement that requires no special tools.
We ship worldwide with tracking on every order. All purchases are covered by a 30-day money-back guarantee so you can return the filter if it does not meet your needs. We also offer a price-beat guarantee, if you find a qualifying lower price elsewhere, we will beat it.
