Importance of offline filtration system use

Abstract

Any machine which uses mineral oil for power transfer or lubrication is dependent on the condition of the oil. Maintaining oil performance and machine components at their best is therefore vital. System filters are primarily the last line of defense, but are not conductive to achieving optimum oil cleanliness, as pressure shocks will result in the release of a large amount of the particles already retained by the filter insert. However, originally installed (suction, pressure, return) filters are still important as last chance inline filters. Secondary oil filtration is ideal for ensuring the lowest possible degree of contamination in the system, e.g. to achieve a specific level of oil cleanliness. Because of secondary filter circuit works independently of the hydraulic or any other oil lubrication system, its level of efficiency remains constant – in any situation of system operation. This paper will present reasons that justify use of an secondary filtration system.
