UH310 Series high pressure filter elements are designed to provide stable, long-term contamination control in demanding hydraulic systems. Multiple micron ratings and element lengths allow users to balance cleanliness requirements with service life and operating efficiency.


In high-pressure hydraulic systems, filter elements play a decisive role in protecting critical components such as pumps, servo valves, and proportional controls. The UH310 Series high pressure filter elements are engineered to maintain consistent particle capture efficiency throughout the entire service interval, even under fluctuating flow and pressure conditions.
Ayater supplies UH310-compatible filter elements that meet the original dimensional and performance requirements, enabling seamless replacement in existing installations. These elements are suitable for both continuous-duty industrial systems and mobile equipment exposed to vibration and pressure cycling.
By combining high-efficiency filtration media with a mechanically robust construction, UH310 elements help reduce system wear, slow fluid degradation, and extend overall maintenance intervals.
UH310 filter elements utilize inorganic fiber media impregnated and bonded with epoxy resins, providing excellent structural integrity and resistance to collapse. The media is designed with an anti-static configuration, minimizing the risk of electrostatic discharge that can damage fluid properties in high-flow applications.
All UH310 elements are rated at Betaₓ(c) ≥ 2000 according to ISO 16889, ensuring extremely high particle removal efficiency across the full operating life of the element.
| Element Code | Micron Rating | Typical Application |
|---|---|---|
| UE310AZ | 3 µm | Servo and proportional valve protection |
| UE310AP | 5 µm | Precision industrial hydraulics |
| UE310AN | 7 µm | General high-pressure systems |
| UE310AS | 12 µm | Mobile and heavy-duty equipment |
| UE310AT | 25 µm | Pre-filtration and return line circuits |
Nominal element lengths are available in 8", 13", 20", and 40", allowing users to increase dirt-holding capacity and extend service intervals without increasing housing size.

UH310 filter elements are optimized for low clean pressure drop, supporting reduced energy consumption and stable system temperature. As contamination accumulates, the pressure increase remains predictable, allowing accurate monitoring via differential pressure indicators.
Element burst pressure: 10 bar (150 psid)
Stable performance under variable flow conditions
Consistent filtration efficiency from start-up to change-out
Fluid Compatibility
UH310 elements are compatible with a wide range of hydraulic fluids, including:
Petroleum-based hydraulic oils
Water glycols and water-oil emulsions
Synthetic hydraulic and lubrication fluids
This versatility allows standardization of filtration components across multiple systems and applications.
