The hydraulic oil filter core is used in various oil systems to remove solid impurities produced by external mixing or internal operation of the system. It is mainly installed on the oil suction road, pressure oil road, return pipeline road and bypass road in the system, and on the separate filtration system.

It is used to protect specific components in hydraulic system. It is installed in upstream of medium pressure pipeline, which needs to be protected, in order to filter out solid particles and colloidal substances in working medium, effectively control contamination of working medium and make components work normally.

Hydraulic oil filter mainly use stainless steel woven wire mesh, sintered wire mesh, iron net as frame, because it uses glass fiber filter paper, chemical fiber filter paper, wood pulp filter paper as main filter material .It has high heart rate, high pressure, without any burr, long service life characteristics.
