Diesel Particulate Filters, also known as DPFs, are exhaust after-treatment devices that significantly reduce emissions from diesel-powered vehicles and equipment. In addition to regeneration, the filter must be periodically cleaned to remove excessive noncombustible materials and ash.  At Tennessee Fleet Service we do forced regeneration on Cummins and Detroit and can take care of all of your DPF system needs.
