 Core Function Interpretation

Hydraulic oil filters are like the "kidneys" of a hydraulic system, primarily removing mechanical impurities like metal powder generated by wear and tear on various system components, keeping the oil circuit clean and thus extending the life of the hydraulic system. The FOS-618PLP8, a fine filter, is typically installed in the return oil section, providing final purification.

 Important Features and Standards

- Bypass Valve Design: Some filter elements (especially low-pressure series) are designed with a bypass valve. If the filter element becomes clogged and is not replaced promptly, the bypass valve automatically opens, protecting the system from shutting down due to excessive resistance.

- International Testing Standards: High-quality hydraulic oil filters are typically tested against a series of rigorous international standards, such as burst resistance (ISO 2941), structural integrity (ISO 2942), and material and fluid compatibility (ISO 2943). When purchasing, be sure to check if the product meets these standards.

Applications

This type of filter element is widely used in a variety of industries, including metallurgy, textiles, electronics, pharmaceuticals, thermal power generation, construction machinery, papermaking, and machine tool manufacturing.
