Mann-Filter to present three stage fuel filter 10 August 2016

Mann-Filter says it will be showcasing new diesel fuel filters designed for three-stage water separation at the upcoming Automechanika event (Frankfurt, Germany, 13—17 September 2016).

The company says its new filters achieve 90% water separation efficiency with a new level of consistency, making them better able to prevent damage in today’s trucks’ advanced common rail diesel injection systems.

The company makes the point that even high-quality diesel may contain traces of water, from moist air entering through the tank opening or from condensation in diesel storage tanks.

Additionally, higher proportions of biofuel result in the formation of small but stable water drops and require better water separation technology.

That matters with injection systems running at pressures up to 2,500 bar, which demand more in terms of fuel purity than their mechanical predecessors.

Tiny dirt particles or water droplets can damage components, which, in the worst case, can result in system failure.

Mann-Filter’s new PU 9005 z and PU 10 011 z diesel fuel filters offer three-stage filtration – starting with a solid dirt unit, followed by a coalescer fleece, which removes fine water droplets, and finally a hydrophobic sieve ensuring that coalesced drops do not enter the injection system.

Gravity causes the separated water to collect in a collection chamber while an on-board sensor signals as soon as drainage is required.

Mann and Hummel says it is already mass producing the new diesel fuel filters for several manufacturers.
