High-Contamination Environments
In mining, construction, or quarrying equipment where hydraulic oil picks up abrasive particles, the wire mesh media withstands heavy soiling and can often be cleaned and reused. This reduces replacement frequency and helps keep machinery on the job longer.
Continuous-Duty Systems
For manufacturing presses or power generation sets operating around the clock, the bypass valve opens at 3 bar to maintain oil flow even as the element loads up. Combined with the 20 bar collapse strength, it prevents cavitation and protects expensive downstream components.
Inventory Consolidation
Many Hydac-equipped facilities stock different filter part numbers for similar housings. Using SPM-HYD-1794 as a direct replacement across multiple compatible assemblies simplifies procurement, lowers inventory costs, and ensures consistent filtration performance site-wide.
Cold-Weather Operations
When hydraulic oil thickens during winter startup, the 3 bar bypass valve permits fluid to circulate without starving the pump. This element’s robust design prevents cold-weather pressure spikes and helps avoid nuisance alarms or shutdowns.
SPM-HYD-1794 is engineered to fit specific Hydac filter housings. As model-specific cross-references are not listed, verify your existing element’s dimensions against this unit: total height 413 mm, outer diameter 114.5 mm, and inner diameters of 68.4 mm (largest) and 65 mm (smallest). A match assures correct fitment.
This element uses a wire mesh media rated at 50 microns. Wire mesh is a durable, cleanable option that provides consistent particle removal and resists collapse under differential pressure, making it suitable for hydraulic oil in heavy-duty applications.
Yes, it features a bypass valve set to open at 3 bar. Key dimensions are a total height of 413 mm, largest outer diameter 114.5 mm, and inner diameters of 68.4 mm and 65 mm. Note that this element has no threaded connections.
SPM-HYD-1794 is built to match OEM specifications for fit and function. It is not a Hydac-branded product, but it delivers equivalent filtration and durability at a more competitive price, supported by our 30-day money-back guarantee and price-beat promise.
Installation is identical to the original element. Remove the housing cover, extract the old filter, clean the housing interior, and insert the new element ensuring the out-in flow direction is correct. Always follow your equipment’s priming and leak-check procedures after servicing.
We ship worldwide with full tracking. Every SPM filter is backed by a 30-day money-back guarantee and our price-beat guarantee. If you find an identical product cheaper elsewhere or are not satisfied, contact us for a resolution.
