    Mobile Fine Dust Particle Filter

    The emissions in a city are produced by power stations, factories and households. Motor cars, transport vehicles, busses and railways also harm the environment and human health. These vehicles move around frequently in confined spaces during the day. If it were possible to improve the overall balance for the particulate emissions of these vehicles, it would also be possible to reduce the level of air pollution.

    The MANN+HUMMEL fine dust particle filter enables vehicles to compensate for the emissions they release to the ambient air. When fitted, for example, to the roof or underbody of a vehicle, the filter can retain particulates present in the air. For this purpose, blowers convey ambient air into the system mounted at the vehicle. The filtration specialists use sensors and contact to a network cloud to record and assess the filtration performance and also collect air and weather data.
    First tests indicate that the filter retains as many particulates from the ambient air as a vehicle with a modern gasoline or diesel engine emits in the combustion process.

    Stationary Fine Dust Particle Filter

    Air pollution is particularly high at locations where there is a high concentration of traffic or emissions from chimneys and a low exchange of air. If large numbers of people regularly frequent these places such as big road junctions, railway stations or subways, this can be especially harmful to their health. The installation of stationary fine dust particle filters at such locations can be used to improve the air quality.

    MANN+HUMMEL is currently testing a filter column, it has installed in front of its Technology Center in Ludwigsburg. The filtration experts have integrated a fine dust particle filter and blowers in a column which also functions as a poster pillar. The blowers suck in ambient air and the filter retains particulates from the air. The filter performance can be controlled to match the level of air pollution in order to minimize the amount of energy which is required.

    At bus stops or railways stations the particle filter can be integrated in advertising panels or information walls.

    Brake Dust Particle Filter

    Wear abrasion of the brake disks and pads in the braking process generates dust. And this is a significantly higher volume of dust than that generated by exhaust gases. Up to now the greater part of these dust particles have entered the ambient air and have contributed towards the bad quality of air in many cities. Fine particles constitute more than 90% of the brake dust and these fine particles can penetrate deep into human lungs.

    The MANN+HUMMEL brake dust particle filter considerably reduces the release of particles to the air directly at the source. It retains 80% of the brake dust. The filtration experts have confirmed this in laboratory tests. They are now testing the performance of the filter under real driving conditions in test drives with Fine Dust Eater vehicles in greater Stuttgart. The filter can find application in motor cars, commercial vehicles, railway applications and industry with all types of power trains including electric, hybrid, gasoline and diesel vehicles.

    NO2 Fine Dust Combi Filter

    In presence of heavy air pollution in cities, significant amounts of particles and harmful gases could possibly enter the interior of vehicles leading to high concentrations of pollutants inside the vehicles. The NO2 fine dust combi filter from MANN+HUMMEL protects the vehicle occupants against the risks to health posed by air pollution.

    A particle filter layer coated with ultra-fine nanofibers enables improved protection against fine particulates. The use of different layers of activated carbon enables the filter to offer improved protection against numerous harmful gases such as toxic nitrogen oxides. Due to special coating of the filter also ammonia can be reduced on a higher level, while a biofunctional layer binds allergens and prevents the growth of bacteria. As a result unpleasant odors are reduced.

    The NO2 fine dust combi filter is installed in the Fine Dust Eater vehicles. In general, it is suitable for use with all passenger cars, commercial vehicles, the railway sector and industrial applications.
