There are a number of various filtering materials used for fuel filtration, depending on required optimal efficiency and contaminants absorption. They can be special polyester non-woven materials or cellulose based filtering paper applied for fine cleaning. New filtering materials are made of synthetic or semi-synthetic materials combinations, which form multi-layers partition able to trap contaminants selectively. It guarantees prolonged filters service life without loss of fuel purification quality.

Filtering elements, designed for diesel fuel cleaning, also obligatory required to separate efficiently water emulsions from fuel.
