German filter manufacturer, MANN+HUMMEL, has successfully tested its Fine Dust Particle Filter, showing that the filter achieves the targeted separation efficiency of 80% of particulates (PM10).
The company introduced the system for the first time in 2017 and since then, the filter specialist has tested the technology in its Fine Dust Eater project, with experimental vehicles in Germany, India, and China. Reports show that, at high particulate pollution levels in city traffic, the filter removes more particulates from the air than a vehicle with a modern internal combustion motor emits from its exhaust. It achieves its targeted separation efficiency of 80% and the filter elements allow air to flow through with minimal pressure loss (about 1 millibar).
Installed on the roof or under the floor of a vehicle, the filter strains particulates out of the air. The particularly low flow resistance of the filter elements used permits 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, allowing the vehicles to filter out particulates from 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.
