• Collapse Pressure Rating: 2.1 MPa (Standard) up to 21 MPa (High-Pressure)

• Operating Temperature Range: -30°C to +110°C

• Beta Ratio: $\beta_x \ge 200$ (High efficiency)

• Construction: Reinforced cold-rolled perforated steel core with anti-corrosion coating

Key Technical Advantages:

• Multi-Layer Depth Filtration: A复合结构 (composite structure) media captures coarse particles on the outer layer and ultra-fine contaminants on the inner layer, significantly increasing dust-holding capacity.

• Reinforced Structural Core: Featuring a heavy-duty cold-rolled steel center tube, our filters are engineered to withstand extreme high-pressure fluid surges without collapse or deformation.

• Advanced Sealing Integrity: High-grade NBR or FKM (Viton) seals guarantee zero leakage, even under aggressive high-pressure operational environments.

• Universal Fluid Compatibility: The filter media is synthesized from chemically stable fibers, ensuring full compatibility with mineral oils, synthetic oils, emulsions, and water-glycol fluids.

Application Areas:

• Heavy Construction Machinery: Main hydraulic and pilot circuits for excavators, wheel loaders, and cranes.

• Metallurgical Industry: High-pressure hydraulic control systems for continuous casting machines and rolling mills.

• Industrial Manufacturing: CNC machines, injection molding machines, and heavy-duty hydraulic power units.

• Power Generation: Hydraulic pitch control systems for wind turbines and auxiliary systems for gas turbines.

Expert Maintenance Tips:

• Monitor Differential Pressure: Always pay close attention to the bypass valve alarm. Replace the element immediately once the differential pressure indicator reaches the threshold; running a system with an open bypass valve allows contaminated oil to cause rapid component wear.

• Installation Best Practices: When replacing the element, clean the filter housing bowl thoroughly to remove any metal shards or sediment. Lubricate the new seal with clean hydraulic oil to ensure a perfect seat.

• Handle with Care: Avoid applying excessive pressure to the filter end caps during installation to prevent damage to the seal interface.
