Key Technical Advantages:

• Multi-Layer Gradient Media: Utilizing graded-pore fiber media, our filters capture contaminants of varying sizes across different layers. Large particles are caught on the outer layers, while fine particles are trapped in the depth, drastically increasing total dirt-holding capacity and operational life.

• High-Strength Stainless Steel Core: Featuring a high-strength perforated stainless steel core, our filters offer superior anti-collapse performance. Even under cold-start pressure surges or pump pulsation, the filter maintains structural integrity, preventing media rupture and downstream contamination.

• Superior Chemical Compatibility: End caps and seals are crafted from oil, acid, and alkali-resistant Viton or NBR materials. This ensures compatibility with a wide range of hydraulic media, including synthetic oils, mineral oils, and water-glycols, preventing seal degradation.

• Low-Resistance, High-Flux Design: CFD-optimized pleated wave geometry maximizes effective filtration area without compromising precision. This significantly reduces initial pressure drops, helping to minimize system energy consumption and operational heat buildup.

Application Areas:

• Metallurgical Equipment: Hydraulic stations for rolling mills and continuous casting servo-control circuits.

• Power Generation: Governor systems and hydraulic actuators for power plant facilities.

• Advanced CNC Machining: High-precision machining centers and automated hydraulic production lines.

• Heavy Construction Machinery: Tunnel boring machines and ultra-large scale excavators.

Expert Maintenance Tips:

• Proactive Replacement: Do not wait for complete blockage. Install a differential pressure indicator and replace the element when pressure drops reach 75% of the rated limit to prevent bypass valve activation and unfiltered fluid bypass.

• Installation Cleanliness: When replacing, thoroughly clean the interior of the filter housing and inspect the walls for residual metallic debris.

• Sealing Integrity: Ensure the O-ring is seated correctly and evenly to prevent bypass effects or external system leaks caused by improper seal installation.
