New Mann-Filter centrifuge rotor for Scania applications
Mann-Filter has introduced its new ZR 9008 z centrifuge rotor filter, in genuine OE-quality for the Scania G and P series, incorporating a plastic centrifuge rotor for easy, hassle-free servicing.
Oil centrifuges are used in addition to the main oil filter and separate the finest impurities from the engine oil. With global tightening of emissions regulations in commercial vehicles, the demands on the efficiency of oil filtration are also increasing.
The centrifuge rotor is driven by the oil pressure in the engine, reaching speeds of up to 11,000 revolutions per minute.
This creates centrifugal forces in excess of 2,000 times the force of gravity, which effectively remove impurities from intake air, metallic dirt particles from engine abrasion and soot from combustion.
As these particles have a higher density than the oil, they are separated from the liquid and removed at the edge of the centrifuge.
The higher the rotation speed, the more particles can be separated. The removed particles are stored in layers as a solid dirt ‘cake’ on the inner wall of the rotor. The cleaned oil then flows back into the oil sump.
The ZR 9008 z rotor is replaced during the service and is a simple ‘remove & replace’ part.
