The process of filtration und separation takes place in two element stages. In the first stage, known as the Coalescer stage, during flow through the element from the inside to outside solid particles are retained by the star-shaped folded paper layers. At the same time emulsion separation begins in the pleated paper section. Next the fuel-water mixture flows through the Coalescer part of the element. Due to its hydrophobic and hydrophilic properties very small and fine water droplets coalesce by retardation, acceleration and deflection of the liquid flow to form larger droplets. Afterwards they drop into the water sump because of their higher specific weight. %u25A0 for stationary application %u25A0 according to API/EI 1581 5th Edition, Category C, Type S %u25A0 for Jet A1, JP 1, JP 4, JP 8, kerosene %u25A0 maximum flow rates up to 7.720 l/min %u25A0 max. 15 ppm free water in the outlet stream %u25A0 max. 0,26 mg/l (average) particles in the outlet stream
