MANN+HUMMEL Successfully Tests Fine Dust Particle Filter

Ludwigsburg, Frankfurt, Hannover, September 4, 2018 - The use of the newly developed MANN+HUMMEL Fine Dust Particle Filter can improve the particulate emissions balance of vehicles and reduce air pollution.

Traffic contributes a significant portion of the particulate pollution in cities. Cars, transportation vehicles, buses, and trains are damaging human health and the environment due to emissions. They move back and forth in a restricted region, frequently multiple times a day. The filter specialist MANN+HUMMEL will exhibit the Fine Dust Particle Filter during Automechanika and IAA Commercial Vehicles this month.

MANN+HUMMEL introduced the system for the first time in 2017 at a very early stage in its development. Since then, the filter specialist has tested the technology in its "Fine Dust Eater" project, with own experimental vehicles in Germany, India, and China. Reports to date have shown that at high particulate pollution levels in city traffic, the Fine Dust Particle Filter removes more particulates from the air than a vehicle with a modern internal combustion motor actually emits from its exhaust. The filter achieves the targeted separation efficiency of 80 percent of particulates (PM10). The modern filter elements allow air to flow through with minimal pressure loss (about 1 millibar). The additional energy consumption is correspondingly negligible.

Installed on the roof or under the floor of a vehicle, for example, the filter strains particulates out of the air. The particularly low flow resistance of the filter elements used permit the maximum possible volume flow and a high separation performance with very low energy demands. Fans also suck in air from the environment, supporting the ambient air flow towards the element. This means that vehicles can filter particulates out of the surrounding air even when the vehicle stands still. Sensors and a connection to a cloud allow data about air, weather, and filtration performance to be collected and analyzed.

Current Developments
The commercial vehicle supplier SAF-HOLLAND is going to test the Fine Dust Particle Filter on its trailer with electrified axles during experimental trips on test roads, as well as in city and country road tests. These will start in the next few weeks.
The interest of AL-KO Fahrzeugtechnik, among other things a manufacturer of chasses for light commercial vehicles and for motorhomes, has also been awakened by MANN+HUMMEL and its Fine Dust Particle Filter. At IAA Commercial Vehicles, the company will exhibit a chassis that acts as a system carrier for the Fine Dust Particle Filter.

Further information
About 47,000 people in Germany die every year from particulate matter, according to WHO estimates. MANN+HUMMEL is carrying out a research project called "Fine Dust Eater" to reduce particulate pollution in urban concentrations. In August of 2017, a field test with an experimental vehicle started in the Stuttgart region, testing different filter technologies. One of those is the Fine Dust Particle Filter for mobile and stationary use. In the meantime, the project has been expanded to more vehicles and other countries (India, China). The particle filter will be put into use in stationary form at the Neckartor in Stuttgart starting in October 2018. More at www.finedusteater.com
