What are the materials of hydraulic oil filter element

The materials of hydraulic oil filter mainly include the following:
Metal mesh material:
Stainless steel woven mesh: It has the characteristics of high strength, corrosion resistance, and high temperature resistance, and is one of the common materials in hydraulic oil filter cartridges.

Sintered mesh: Made through a special sintering process, it has a porous structure, high filtration efficiency, and is suitable for high-precision filtration.
Iron weaving network: The cost is relatively low, but it may not be as good as stainless steel in terms of corrosion resistance and high temperature resistance.
Fiber material:
Fiberglass filter paper: Made from glass fiber as raw material, it has high filtration accuracy and can effectively remove small particles and pollutants in hydraulic oil.
Chemical fiber filter paper: The cost is lower, but the filtration efficiency and durability may be slightly inferior to fiberglass filter paper.
Wood pulp filter paper: It is also used in certain specific applications, but relatively rare.

Other materials:
Polyester fiber: Low cost, good filtration performance, suitable for some occasions where high filtration accuracy is not required.
Natural synthetic fiber fabrics, synthetic fiber fabrics, galvanized wire mesh, etc.: These materials are also used in some hydraulic oil filter cartridges, and suitable materials should be selected according to specific needs.
In addition, the components of the hydraulic oil filter element also include the outer frame, end cover, sealing ring, support frame, and bypass valve. These components together ensure the filtration performance and service life of the hydraulic oil filter element.
