use of the newly developed MANN+HUMMEL Fine Dust Particle Filter can improve the particulate emissions balance of these vehicles and reduce air pollution. The filter specialist MANN+HUMMEL will exhibit this technology 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.
