The German INTERNORMEN filter element is a new type of hydraulic filter element. The hydraulic oil often contains particulate impurities, which will cause the wear of the relative moving surface of the hydraulic components and greatly reduce the reliability of the system. Installing a certain precision oil filter in the system is to ensure that according to the material and structure of the filter element, the oil filter can be divided into mesh type, line gap type, paper filter type, sintered oil filter and magnetic oil filter, etc. , They can filter out impurities larger than 100μm, 10-100μm, 5-10μm and 1-5μm respectively.
