Expertise in the plain bearing field led to the development of a range of centrifugal oil filters which are designed to remove dirt particles of as small as 0,1 microns in size without the use of filter elements. Their efficiency is unparalleled and no consumable elements are required. The basic principle of operation is that the internal rotor is driven by external pressure to a maximum of 700kpa. This oil pressure then turns the rotor at high speeds thus creating the centrifugal action which separates the dirt particles from the oil. The units can be fitted as a bypass to existing systems or alternatively operated with their own individual oil pressure pump.
