features

Structural characteristics: Oil filter cartridges are usually made of single or multiple layers of metal mesh and filter material, with the number of layers and mesh size of the mesh depending on different usage conditions and purposes. It has high concentricity, high pressure resistance, and good straightness. It is usually made of stainless steel material without any burrs, ensuring a long service life.

Filtering effect: The main function of the oil filter element is to filter out impurities, gum, and moisture in the engine oil, and deliver clean engine oil to various lubrication parts, thereby protecting the engine.

Material and manufacturing process: The oil filter element is made of stainless steel material without any burrs, ensuring that no additional wear or impurities are generated during use, thereby extending its service life.

Application scenario: Oil filter cartridges are widely used in automotive engines to filter impurities in engine oil, air, and air conditioning systems, ensuring the normal operation of the system and extending equipment life

Dissolve potassium dichromate or crystals in water to 60 to 80 degrees, and slowly add concentrated sulfuric acid with a concentration of 94% until sufficient. Add slowly and stir. Add up to 1200 milliliters of potassium sulfate or completely dissolve, and the solution will appear dark red in color. At this time, the rate of adding concentrated sulfuric acid can be accelerated until it is completely added. If there are still undissolved crystals after adding concentrated sulfuric acid, they can be heated until dissolved. The function of cleaning solution is to remove general pollutants, grease, and metal particle impurities on the wall of stainless steel filter cartridge, and it can effectively kill the bacteria and microorganisms that grow on the filter cartridge and damage the heat source. If the filter element has been alkaline washed before, the alkaline solution must be washed first, otherwise fatty acids will precipitate and contaminate the filter elementSFN-02-60K SFN-02-100K SFN-02-150K SFN-02-200K
