New Filter System will Battle Particulates from Road Haulage and Other Commercial Vehicles

GERMANY – By now everyone involved with road haulage, and indeed across the transport spectrum and beyond, is aware of the danger of airborne particulates which mainly emanate on land from diesel powered trucks and buses. Now filtration specialist Mann+Hummel has introduced a new weapon into the fight against a pollution which, according to the WHO, kills around 47,000 people annually in Germany alone.

The new Fine Dust Particle Filter from Mann+Hummel was introduced 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. Data reviewed shows 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.

For the technically minded the filter achieves the targeted separation efficiency of 80% of particulates (PM10). The modern filter elements allow air to flow through with minimal pressure loss (about 1 millibar) and the additional energy consumption is correspondingly negligible. The manufacturer will be exhibiting the technology at the upcoming Automechanika Expo in Frankfurt and the IAA Commercial Vehicles Show, Hannover, both later this month.

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 the cloud allow data about air, weather, and filtration performance to be collected and analysed.

German commercial vehicle supplier SAF- Holland is to shortly commence tests using the system on its trailer with electrified axles during experimental trips on test roads, as well as in city and country road tests, whilst AL-KO Fahrzeugtechnik, which produces chassis for light commercial vehicles and for motorhomes, will exhibit a chassis that acts as a system carrier for the Fine Dust Particle Filter at the Hannover event.
