MANN-FILTER at the Automechanika 2014

Filters with signs of wear put on show by MANN-FILTER to demonstrate that original equipment quality is maintained up to the recommended service interval

Ludwigsburg, 15 September 2014 – The combustion engines developed by motor vehicle manufacturers are becoming ever more fuel-efficient and low-emission. This means that the filtration solutions deployed in the vehicle need to meet the associated high demands. As a global market leader in the filtration sector, MANN+HUMMEL supplies high-quality and innovative solutions to help customers meet these challenges.

In order to demonstrate the truth of this statement, MANN-FILTER will be exhibiting filters that have already reached the end of their service life at the Automechanika 2014. These filters have been exposed to the loads that they would have been exposed to in a vehicle up until the recommended service interval. Despite a few signs of wear, the original equipment quality and full functionality of these MANN-FILTER filters are evident.

There are a variety of reasons behind the high quality of MANN-FILTER filters. MANN-FILTER's wide range of innovative solutions and filter media can be tailored to the individual applications and specifications of the vehicle manufacturer, meaning that its air, oil, fuel and cabin filters never fail to impress. Some of the media used are particularly fine-pored in order to achieve high efficiency levels, for example, or have a very high dust holding capacity due to the gradient structure of the fibers. Poor-quality filter media absorb as little as one third as much dirt, which means that they allow significantly more contaminant particles to pass through to the engine. In order to maximise filtration performance over the long term, most MANN-FILTER products also feature a multilayer structure to enhance the dust holding capacity and improve separation efficiency.

The quality, structure and quantity of the materials employed are also key in ensuring a long service life. Special embossing on the filter media is designed to ensure an even and stable pleat distance to ensure optimum filtration performance. This also prevents so-called "packeting", when pleats of paper clump together and reduce the effective filter surface area.

MANN-FILTER uses the innovative glue string technology to make its filters even stronger and more durable. This involves a special string of polyester fiber running in a discontinuous pattern around the air filter bellows, which ensures that the distances between the filter pleats remain even over the complete height of the filter. This has the benefit of significantly lowering the flow resistance and therefore reducing pressure loss, which in turn optimises filter performance and helps save fuel.

Seals and sealing rings also play a crucial role in all segments of the filtration market: they withstand a wide range of temperatures and pressures, are built to fit perfectly and ensure that the filters are easy to install. Finally, the pressure- and corrosion-resistant materials used for the filter bowls guarantee maximum and long-lasting operational safety.

Visitors to Automechanika will be able to find out more, examine the signs of wear on the filters and view other products at the MANN-FILTER stand.
