Lewis Motors inspects and tests the filter at every stage of the cleaning process. Once processed, we know the exact condition of the filter. These results are shared with the customer and compared to previous results.
Our system and the cleaning process has been tested by engineering teams from three major engine OEM’s. These tests determined that the equipment and cleaning program will provide the best cleaning available without damaging the components of the DPF.
Lewis Motors does not guarantee or warrant that we can provide recovery of the filter. Filters can fail for various reasons as a result of extreme operating conditions. Some filters last longer than others.
Overall filter life decreases when impacted ash is left in the filter cells. The deeper the impacted ash becomes the harder it is to remove in the cleaning process. The cleaner the filter is kept the longer the overall life.
