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.
