New fuel filter from MANN+HUMMEL for commercial vehicle diesel injection systems


MANN+HUMMEL has announced the MANN-FILTER PU 12 004 z diesel fuel filter. The pressure-side filter operation is based on a three-stage process. The filter can be recycled as it is made with metal-free elements and can be changed without excessive force. 

In the first stage, the filter medium removes solid dirt particles from the diesel fuel. The second filter stage uses a coalescer fleece. It retains water droplets from the fuel/water emulsion and combines them to form much larger drops. In the third stage, a hydrophobic sieve ensures that the enlarged drops do not enter the injection system. Gravity causes the separated water to collect in a water collection chamber in the filter module. A sensor signals as soon as the water needs to be manually drained or siphoned.
