Separ 2000- Function Stage 1 : from the inlet port, fuel flows through the interior vane system which impart a circular motion to the fuel. Stage 2 : still in the circular motion fuel reaches the bowl section , where, due to this centrifugal motion , water droplets and heavier particles are forced to the wall of the bowl, eventually settling in the bottom ofthebowl. Stage 3 : In this stage the fuel has to pass the vane system positioned on the outside of the central housing. Due to the differing length of the vanes and the twofold rapid change of fuel flow direction , smaller water droplets and finer particles will settle on the vanes. These settlements will agglomerate and when heavy enough fall to the bottom of the bowl already at this point the major portion of any contaminates in the fuel have been separated. Stage 4 : Just below the filter element the flow area of the filter is increased significantly thus reducing the fuel flow rate. This calming effect allows even smaller water droplets and particulate to fall out settling on the inner surfaces of the housing , forming larger droplets which eventually fall into the bottom of the bowl by gravity. Due to the before described pre-separation process, the major portion of water and particulate present in the fuel will be in the bowl or on the inner surfaces of the filter, thus greatly extending the filter element life. Stage 5 : The final filtration of the remaining water and particulate still containedin the fuel will be effected by a replaceable filter element. These filter elements are produced from a special filter media and are available in different pore sizes.
