Product Description hydraulic oil filter cartridge reverse flow filter Basically, hydraulic oil filter is a device containing three types of filter media layers, namely: metal, paper and micro glass elements. As hydraulic oil passes through the filter, it traps and removes particulate matter. As a result, it prevents ingress of foreign particles that may cause damage to hydraulic system. Working Principle of Hydraulic Oil Filter Hydraulic fluid serves a number of purposes in hydraulic systems. Undoubtedly, its core role is to transfer force to the actuators from the hydraulic power unit. However, it also does the following: · To keep the system surface lubricated to avoid friction on metal surface on each other. · Maintain a conducive temperature by transferring from one end to the other. · Seals the hydraulic system through adhesion and surface t…
