MANN-FILTER PreLine® prefilter system

Better filtration for diesel fuel. Longer lifespan for injection systems.

PreLine® is an innovative prefilter solution for diesel fuel systems which ensures a high degree of water separation and particle pre-separation. The modular retrofit system is tailored to the most modern diesel direct injection systems for industrial diesel engines. These use sensitive technology and therefore require a particularly high level of fuel quality. For error-free operation, everything from the smallest particles through to large quantities of water must be efficiently separated from the fuel.

The PreLine® modular assembly system meets these requirements perfectly. As it is based on the principle of the spin-on filter, it is cost-effective, can be used universally and is easy to operate. With a water separation efficiency of over 93% and a long service life, PreLine® provides a whole range of advantages: all modern high-pressure injection systems are reliably protected from corrosion and abrasion, the service life of the main filter is increased and the frequency of repairs reduced.
