Core Functions and Application Scenarios

1. Main Functions
Precision Filtration: Multi-layer glass fiber filter media intercepts particulate impurities larger than 10μm, controlling oil cleanliness ≤NAS 8 level
Differential Pressure Protection: Integrated bypass valve (opening pressure…) 0.35MPa±0.05MPa), preventing filter element clogging and system flow interruption.
Oil-water separation: Assists in separating free water in the oil, with a water separation efficiency ≥95%, preventing corrosion of hydraulic components.
Low resistance and high efficiency: Optimized folded structure design, flow resistance is 30% lower than comparable products, without affecting system flow output.
Expanded dirt holding capacity: Extra-large effective filtration area design, extending filter element lifespan and reducing replacement frequency.

2. Suitable operating conditions
Highway, airport runway construction, and other dusty, heavy-duty operating environments.
Continuous operation scenarios for hydraulic oil circulation filtration.
Harsh operating conditions such as mud and water erosion, and alternating high and low temperatures (-20℃~150℃).
Composite hydraulic circuits where steering systems and working devices operate in tandem.

Product advantages

Original factory compatibility: Fully matches the GR2605 hydraulic system installation dimensions and interface standards, direct replacement without modification.
High purification efficiency: 10μm high-precision filtration + 98% High retention rate, effectively protecting precision components such as hydraulic pumps and control valves. Long-lasting and durable: Imported glass fiber filter media + stainless steel frame, large dirt-holding capacity, and service life increased by more than 16% compared to similar products. Safe and reliable: Integrated bypass valve and differential pressure alarm function to prevent system overload damage, suitable for high-pollution conditions. Easy maintenance: Standardized threaded installation design, simple disassembly and assembly; recommended replacement cycle of 500 hours (can be shortened in harsh environments).
