Use cases & applications
Continuous-Duty Hydraulic Systems
In systems that run for extended periods, the 40 µm wire mesh media ensures consistent filtration without clogging quickly. The 20 bar collapse pressure handles pressure spikes common in continuous operation, reducing downtime for element changes.
High-Contamination Environments
For equipment operating in dusty or dirty conditions, the wire mesh media is cleanable and reusable, lowering replacement costs. The robust construction withstands repeated cleaning cycles, maintaining filtration efficiency over time.
Inventory Consolidation for Multi-Brand Fleets
Fleet managers with mixed-brand hydraulic systems can standardise on this single element, as it cross-references multiple major brands. This simplifies stock management and reduces the risk of fitting the wrong filter.
Cost-Sensitive Maintenance Programs
Budget-conscious operations benefit from the aftermarket pricing without sacrificing performance. The element meets the original dimensions and ratings, ensuring reliable protection for hydraulic components while lowering per-filter costs.
