MANN+HUMMEL Releases Fuel Filter Disassembly Tool

[Counterman]

MANN+HUMMEL announced the parts kit for its MANN-FILTER fuel filter PU 10 023/1 z KIT for pickups makes maintenance easier, thanks to the patented disassembly tool. It offers a very high degree of particle separation and efficient water separation, while also being ideally equipped for future fuel filtration requirements, the company said.

“Efficient, fast, and clean – this is how the significantly improved handling of the PU 10 023/1 z KIT can be summed up,” explained Frank Bartel, product manager fuel filters at MANN+HUMMEL. This is made possible by the innovative handhold developed by

, which facilitates disassembly and is included with every filter, and by the modern and functional design of the filter element and housing cover. Changing the filter without this grip, however, requires a lot of force and is only possible with pliers or similar tools.

Resistant to Dirt and Water

“The innovative filter has an extremely high separation efficiency of more than 96 percent with a particle size of four micrometers,” MANN+HUMMEL said. “This means that 9,600 out of 10,000 incoming particles are retained. For context, these particles are up to 25 times smaller than a human hair.”

It is not only impurities that can have a negative effect on the components of the injection system, but also water droplets. This applies particularly to modern common rail systems, which place high demands on fuel quality. The MANN-FILTER PU 10 023/1 z KIT filters out more than 95 percent of the water contained in the fuel and operates in three stages, the company said.

In the first step, the filter medium reliably removes solid impurities from the diesel. The second filter stage works with a coalescing fleece that absorbs the finest water droplets from the fuel/water emulsion and combines them into much larger droplets. In the third filtration step, a water-repellent screen fabric ensures that the enlarged droplets do not enter the injection system. MANN+HUMMEL said it has developed this screen fabric in such a way that it is elastic and can withstand the mechanical requirements of pressure and temperature both during operation and at standstill. Bartel explains: “Thanks to its flexible design, it can effectively absorb the forces that arise and so has proven to be particularly robust, including in situations such as when the fuel freezes.”

The seal materials of this fuel filter are resistant to standard diesel, biodiesel variants, and novel synthetic diesel fuels such as hydrogenated vegetable oils (HVO). They have the corresponding OE approvals and ensure a permanent hold as well as the complete sealing of the filter.

Series Supplier

said it has already started series production of this highly efficient fuel filter for a renowned vehicle manufacturer. The filter is available on the independent automotive aftermarket in original equipment quality as a PU 10 023/1 z KIT for various Ford Ranger pickup models and complements the extensive MANN-FILTER product range.

MANN+HUMMEL has been granted a patent for the disassembly handhold by the German Patent and Trademark Office as well as in other countries. Worldwide, more than 1,200 researchers and developers at MANN+HUMMEL work on pioneering solutions with the aim of creating real added value and optimally meeting customer needs, the company said.
