The hydraulic mesh filter utilizes a specialized woven metal mesh as its core filter medium. Its uniform, precise mesh structure achieves rigorous physical screening, ensuring consistent filtration accuracy. This structure effectively intercepts particles above a specific size, fundamentally eliminating the accuracy fluctuations and impurity penetration issues that can occur with fiber filter elements due to uneven material density. Its core advantage lies in its ability to consistently filter out even smaller particles, providing a higher level of cleanliness protection for hydraulic systems.
The metal mesh structure offers exceptional mechanical strength and integrity, easily withstanding the high-pressure fluctuations and frequent shocks of the hydraulic system without deformation or damage. In contrast, fiber filter elements can experience fiber compression or shedding under prolonged pressure, potentially becoming a source of contamination within the system. The robustness of the metal mesh filter element ensures its exceptionally long service life and reliability under harsh operating conditions.
The mesh filter’s smooth surface and regular pores trap contaminants primarily on the surface of the filter medium, preventing them from penetrating deeper into the filter. This significantly reduces filter element clogging. This structure allows for thorough cleaning through high-pressure backwashing, ultrasonic cleaning, and other methods, enabling multiple reuses, significantly reducing maintenance costs and the frequency of spare part replacement. Fiber filters, on the other hand, tend to trap contaminants deep within, making them difficult to effectively clean and typically requiring only disposable supplies.
Metal mesh filter elements offer excellent resistance to a wide range of high-viscosity hydraulic oils, emulsions, and synthetic esters. Unlike filter media susceptible to chemical changes (such as activated carbon), metal mesh filters are unaffected by fluctuations in the chemical properties of the medium. Their filtration efficiency remains stable and reliable, unaffected by changes in oil quality or deterioration in water quality (in oil-water mixtures).
