Why Centrifuge ?

Diesel engines create soot and wear particles that contaminate their lubrication systems. These particles are often sub-micron and cause premature wear to the engine and reduce the effective working life of the engine oil. A centrifuge is a by-pass filter, typically operating of 10% oil supply from the oil pump.

Couple this with a traditional full-flow filter and you have an effective cost solution to reducing wear, prolonging lube life and reducing soot emissions. The rotor is cleaned at service intervals thereby reducing waste disposal and consumable costs, reducing the cost of ownership.


The oil from a pressure point on an engine is fed through the side inlet of the Centrifuge. When the oil pressure exceeds 1.3 to 2.5 BAR, the spring loaded plunger will be pushed back and the oil enters the rotor assembly through the central spindle. The rotor assembly gets pressurized and the only exit point for the oil are the two tangentially opposed nozzles at the base. The rotor assembly has two bushes, one at the top and one at the bottom and spins freely around the spindle. The action of oil exiting through the nozzles gives it a reverse direction spin.

The RPM is directly proportional to the inlet pressure. The oil is returned back under gravity through the central hole at the base of the centrifuge. At 5 BAR pressure the RPM generated for a model LC50 is 7400 which generates centrifugal force 2000 times that of gravity. Thus, any particle heavier than oil is compacted onto the inner rotor wall. At pre-determined intervals this can be easily cleaned with the help of a wooden spatula.

The centrifuge has no consumable parts and is capable of removing sub micron particles from the oil. Ensure that the minimum operating pressure is at least 4 BAR and should not exceed 7 BAR. Optimum results are achieved at 5 BAR pressure.

Importance of removing carbon soot by using Centrifuge.

Centrifugal force is capable of removing a wide range of particles extending into the sub-micron range. Analysis of the dirt collected by centrifuge reveals an ability to remove particles of less than one micron in size including engine clogging soot, oil films protecting critical engine components are equally as small. If not removed contaminant particles in this size range cause component wear and a consequent reduction of engine durability.
