Product Overview

Our Hydraulic Oil Filters are high-performance filtration solutions designed to effectively remove solid contaminants, particles, and sludge from hydraulic fluids, safeguarding critical components in hydraulic systems such as pumps, valves, cylinders, and servo motors. Engineered for industrial reliability, they maintain oil cleanliness, reduce component wear, minimize downtime, and extend the service life of your entire hydraulic system.

High Filtration Efficiency

Adopts premium glass fiber, stainless steel sintered mesh, or high-grade cellulose filter media with a star-pleated structure, delivering precision filtration from 1μm to 100μm. Achieves a filtration efficiency of up to 99.5% per ISO 5011 standards, effectively capturing micro-particles and impurities.

Large Dirt-Holding Capacity & Long Service Life

Expanded filter area design provides exceptional contaminant retention, reducing replacement frequency and lowering maintenance costs. Stable performance under continuous operation.

High Pressure Resistance & Durability

Robust housing constructed from high-strength aluminum alloy or carbon steel (zinc-plated), capable of withstanding operating pressures up to 210–420 bar (3000–6000 psi). Resists hydraulic shock and vibration.

Low Pressure Drop

Optimized flow path and high-permeability media ensure minimal resistance, preserving system response speed and energy efficiency. Pressure loss ≤ 0.1 MPa at nominal flow.

Integrated Safety Design (Optional)

Equipped with bypass valve (standard cracking pressure: 6 bar) and differential pressure indicator to alert for filter clogging and prevent system starvation.

Excellent Compatibility

Compatible with mineral oils, synthetic esters, and most standard hydraulic fluids per ISO 2943. Seals use NBR (nitrile rubber) or optional FKM (Viton) for high-temperature resistance.
