Vehicle Cleaning

The quality and efficiency of the DPF cleaning system “FilterMaster for cars and more” is impressive. Since no cutting or welding is required, the entire housing, including the pipes, remains intact. The DPF cleaning process previously used for car exhaust diesel particulate filters is therefore is no longer contemporary and no longer competitive in terms of preserving the value invested in them. The method also differs significantly from cleaning equipment and washcoat that rinses the filter with water and/or with water-based or other chemicals. Water can penetrate in the porous “washcoat” – which binds the catalytic metal particles. In contrast “FilterMaster for cars and more” operates with purified compressed air to which a microscopic amount of active agent is added as an aerosol for a short time. The active agent is non-toxic and could even be drinkable, except for its unpleasant taste. Research and practical experience have shown that the active agent will not damage the catalytic surfaces. The fact that the process does not damage exhaust particulate filters has been confirmed by several studies, including one at the University of Paderborn. No damage by the entry of “drinkable chemistry” was shown through the procedure test. The project started in 2011 as part of a two-year grant involving Kipp Umwelttechnik GmbH and the University of Paderborn. The aim of the project was to develop a method for purifying exhaust gas particulate filters without having to dismantle or separate the supply and discharge lines of the filter. This project laid the foundation for the subsequent successful joint development “FilterMaster for cars and more”.
