ELIMINATORFull-flow filterSeries of stacked discs with triple wire mesh elements for strength and durabilityThe filtered oil is passed back into the engine95% of the total flow is directed into the engine5% back flushes the full-flow elements, then:• Half passes direct to sump• Half passes through centrifugeSelf cleaning main element reduces maintenanceCopyright © 2000-2012 Cummins Inc.

CENTRIFUGE (SPINNER FILTER)Pressurised oil spins a rotor assemblyCentrifugal forces cause contaminates to migrateradically outwards to the inner surface of the rotor wall:• Over time, they compact to form a dense „cake‟• Cake can be removed at service intervalOperates in by-pass and processes approximately10% of lube oil before returning it to the engine‟s sumpDoes not rely upon filtration media to removecontaminantsRemoval of particles is based on relative density- not limited to particle sizeSimple and effective in reducing particle contaminationCopyright © 2000-2012 Cummins Inc.
