High Precision Hydraulic Filter Effectively Protect Hydraulic Components & Extend Equipment Service Life

Production Craft & Structural Composition

A complete hydraulic filter element consists of multi-layer filter media, inner support mesh, outer protective mesh, upper & lower end caps, sealing gaskets and central support tube.

1. Multi-layer Gradient Composite Filter Material Outer coarse layer intercepts large particles, inner fine layer captures tiny contaminants, improve dirt holding capacity while preventing filter medium damage caused by sudden flow impact.
2. Deep Pleating Technology Uniform deep pleating maximizes effective filtration area, reduces flow resistance, avoids pressure surge inside hydraulic circuit.
3. Integrated Sealing Structure High-performance nitrile rubber sealing rings achieve zero leakage; firmly bonded end caps prevent bypass contamination.
4. Diversified Structure Types: suction filter, pressure filter, return line filter, offline bypass filter, spin-on hydraulic filters.

Main Filter Media & Applicable Working Conditions

1. Micro-Glass Fiber Filter Media (Mainstream High Precision Grade)

High filtration precision, stable performance under high pressure, resistant to most hydraulic oil. Application: Engineering machinery, CNC equipment, precision hydraulic stations, servo systems.

2. Stainless Steel Sintered Mesh

High temperature resistant, reusable after cleaning, strong anti-impact ability. Application: High temperature hydraulic oil, fire-resistant oil, special high-pressure equipment.

3. Compound Filter Paper

Cost-effective, good dirt holding capacity for general industrial hydraulic circulation systems. Application: Ordinary hydraulic stations, light-load machinery, agricultural equipment.

4. Wire Mesh (Coarse Filtration)

For oil suction port primary filtration, block large solid impurities.

Core Competitive Advantages

✅ Stable High Filtration Accuracy Uniform gradient filter material effectively intercept tiny abrasive particles, reduce component wear and avoid hydraulic valve blockage.

✅ Large Dirt Holding Capacity Optimized deep pleat design extends service cycle, reduce frequent replacement downtime and maintenance costs.

✅ Low Flow Resistance Smooth oil passage keeps stable system pressure, avoid energy loss and equipment power drop.

✅ High Pressure & Impact Resistance Reinforced inner and outer support mesh prevents filter medium deformation or rupture under instantaneous hydraulic impact.

✅ Excellent Sealing Performance Oil-resistant rubber gaskets adapt to long-term immersion in hydraulic oil, effectively avoid unfiltered oil bypass.

✅ Wide Compatibility Can be customized to replace most international well-known brand filter elements; direct plug-and-play without modifying equipment.
