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 paperlayers.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.

The second stage Separator elements separa­tes the smallest water droplets which have been swept along in the Filter/Water Separator by ve­locity. These are retained at the hydrophobic coa­ted surface of the Separator elements and then also collect as a sediment in the water sump.
