Audi VW Fuel Filter - Mahle 1J0127401A

MAHLE diesel fuel filters use high-quality filter media reliably removing contaminants, protecting the engine and assures efficient operation of the vehicle.

MAHLE diesel fuel filters are made from high-grade cellulose fibers impregnated with special resins. These materials are treated in a special production process: special pre-warming prepares the paper for the embossing of vertical ridges. Afterwards, the paper is folded according to requirements. Then the impregnation is cured to make the paper mechanically stable and to make it resistant to chemical and thermal influences.

Water Separation

For newer generations with even higher requirements, MAHLE has opted for two separate filter stages during water separation.

The first filter phase consists of a cellulose filter medium with an untreated melt-blown contact surface for increasing the contaminant absorption capacity. This melt-blown contact surface optimally causes the many small droplets to coalesce into larger ones. The particulate filter in the shape of a pleated star even agglomerates the finest water droplets.

The second filter phase consists of a water separator, whose hydrophobic fabric with a mesh width of 25 µm divides the barely stable emulsion, thus separating the water. As this occurs on the clean side of the filter, it is referred to as clean-side water separation.

Mahle fuel filters comply with the correspondingly high safety standards of the automobile manufacturers and ensure secure sealing even in the event of accidents.
