Filtration is the unglamorous discipline that determines whether expensive equipment fails early or runs for decades. A hydraulic system is only as reliable as the cleanliness of the fluid running through it — contamination ingress through worn seals, inadequate filtration, or poor maintenance practice is the leading cause of premature hydraulic pump and valve failure across virtually every industrial and mobile application. FILTECH, the largest filtration and separation technology event in the world, is where the companies engineering the filters that protect hydraulic systems — and the thousands of other applications that depend on clean fluid — present their latest technology.

FILTECH 2026 brings together 600 exhibitors from 43 countries, covering the complete filtration and separation technology spectrum: liquid filtration, gas and air filtration, membrane technology, separation equipment, filter media, and the testing and measurement instrumentation that validates filtration performance. The show rotates between European venues and has built a reputation as the definitive international gathering for filtration engineers, equipment designers, and the component manufacturers — including hydraulic system designers — who depend on filtration technology as a critical, if often overlooked, system component.

Hydraulic Fluid Cleanliness as an Engineering Discipline

Hydraulic system contamination control has become significantly more sophisticated over the past two decades as system pressures have increased and component tolerances have tightened. A modern axial piston pump operating at 350 bar has internal clearances measured in microns, and particulate contamination that would have been inconsequential in an older, lower-pressure system can now cause catastrophic wear and failure within hours of ingestion. The filtration technology required to protect these systems — high-efficiency particulate filters, water removal systems, and the increasingly important varnish and oxidation byproduct removal technology — has become a specialised engineering field in its own right.

FILTECH's exhibitor base includes companies specifically engineering hydraulic system filtration: high-pressure filter housings rated for the full system working pressure, bypass valve and indicator technology that alerts maintenance personnel before filter blockage causes flow restriction, and the increasingly sophisticated online fluid condition monitoring sensors that allow predictive maintenance based on real-time contamination trending rather than fixed maintenance intervals. These technologies are commercially significant for hydraulic pump manufacturers because filtration system design directly affects the warranty claims and field failure rates their products generate.

Quick Reference

The Conference Programme's Technical Depth

FILTECH's accompanying conference programme is genuinely research-oriented, drawing academic and industrial researchers presenting peer-reviewed work on filtration media engineering, separation efficiency modelling, and the fundamental fluid dynamics of particle capture across different filter media architectures. For hydraulic system designers, this technical depth offers access to filtration science that goes well beyond what a component supplier's own marketing materials would typically convey — genuinely independent research into filter media performance, contamination measurement methodology, and the comparative effectiveness of different filtration technologies for specific contamination challenges.

For hydraulic pump and system manufacturers, FILTECH offers a route to improving total system reliability that operates upstream of the pump itself — better filtration technology extends pump life, reduces warranty costs, and improves the total cost of ownership argument that increasingly differentiates premium hydraulic component suppliers from commodity competitors. Establishing relationships with leading filtration technology companies at FILTECH, and incorporating genuinely superior filtration specifications into hydraulic system designs, is one of the more underexploited differentiation strategies available to component manufacturers competing primarily on pump and valve specifications alone.
