This communication focuses specifically on ash cleaning since ash cleaning is typically associated with the required maintenance of DPFs. There are many factors that determine how ash accumulates in an aftertreatment DPF, such as duty cycle and engine health. How ash accumulates in an aftertreatment DPF influences the effectiveness of the different types of ash cleaning processes. Customer Communication Chemical and Heavy Metal Waste Disposal WARNING The material captured in a partial flow diesel particulate filter and/or a diesel particulate filter may contain elevated concentrations of metals. Primarily zinc, molybdenum, and possibly polynuclear aromatic hydrocarbons, that may be regulated. These materials must be characterized, handled, and disposed of according to applicable local regulations. In addition, due to the presence of the above-listed chemicals and other potentially toxic components such as oxides of calcium, zinc, phosphorous, silicon, sulfur, and iron, exhaust filter maintenance must be completed only by appropriately trained personnel. Air-only Cleaning Air-only cleaning uses compressed air to remove excess ash from the aftertreatment DPF. This process pushes air in reverse of the exhaust flow to remove the excess ash and soot from the aftertreatment DPF. The entire process typically takes about 45 minutes. Air-only cleaning can remove ash that is loosely packed in and not bonded to the aftertreatment DPF. Air-only cleaning is typically a lower cost aftertreatment DPF maintenance cleaning process, but it is less capable of removing densely packed ash or ash that is bonded to the aftertreatment DPF. Liquid Cleaning (most effective) https://quickserve.cummins.com/qs3/pubsys2/xml/en/tsb/2022/tsb220085.html 2/4 5/2/22, 12:38 PM Aftertreatment Diesel Particulate Filter (DPF) Maintenance Liquid cleaning uses some type of liquid, such as water or chemicals, to help remove the bond between the ash and the aftertreatment DPF substrate. This is a longer cleaning process that can take up to several hours. There are different types of liquid that aftertreatment DPF cleaning suppliers can use. As opposed to air-only, liquid cleaning is more effective to loosen ash; however, ash can create a strong bond with the aftertreatment DPF substrate. In this case, water-only, or water combined with air, is not sufficient to clean all types of ash that can accumulate in the aftertreatment DPF. Some readily available suppliers in the market that provide air + water cleaning are: Clean Diesel Specialist (CDS) Emission and Cooling Solutions (ECS) through its DPF RENU program and process Ceramex North America, which works primarily with dealers and fleets Liquids with certain organic chemicals are even more effective at breaking the bonds ash develops with the aftertreatment DPF substrate. When combined with air, it can effectively remove most ash that accumulates in aftertreatment DPFs. Some readily available suppliers in the market that provide this type of service are: Emission and Cooling Solutions (ECS) with its DPF RENU program and process. Note : Chemicals are not used on every cleaning. If sintered ash is found during the liquid RENU process, ECS will consult with the customer on whether to proceed with chemical cleaning. FSX Inc. offers filter cleaning services to OEMs at its centralized location in Granite Falls, Washington. Note : FSX Inc. only offers filter cleaning services on a smaller scale to regional customers (primarily serving the Washington/Oregon region). Each customer needs to evaluate the best option to maintain its aftertreatment DPFs and which cleaning process supports its business needs. Exhaust filter maintenance must be completed only by appropriately trained personnel. Aftertreatment DPF Maintenance and Warranty Guidelines Maintaining Cummins Inc. product is the customers responsibility. If 5383 is the only aftertreatment DPF-related fault code present, the customer can choose where to have the aftertreatment DPF cleaned. If there's a fault code other than 5383 related to an aftertreatment DPF for an out of warranty repair event, the customer should go to a Cummins® authorized service provider for diagnostics and repairs to identify the root cause of the issue. If the aftertreatment DPF is within a Cummins Inc. warranty coverage (base, extended, emissions, new or ReCon Parts) period, and any aftertreatment DPF related fault codes are present, the customer must go to a Cummins® authorized service provider for diagnostics and repairs to identify the root cause of the issue. The authorized service provider will file the warranty claim to Cummins Inc. if the root cause of malfunction is warrantable. https://quickserve.cummins.com/qs3/pubsys2/xml/en/tsb/2022/tsb220085.html 3/4 5/2/22, 12:38 PM Aftertreatment Diesel Particulate Filter (DPF) Maintenance Document History Date 2022-4-25 Details Module Created Last Modified: 26-Apr-2022 https://cst.cummins.com http://edsprod.cummins.com https://gpst.cummins.com https://quickserve.cummins.com https://parts.cummins.com https://store.cummins.com https://wwsps.cummins.com https://access.cummins.com https://commerce.cummins.com https://qsservices.cummins.com https://webparts.cummins.com https://qsservices.cummins.com https://adminportal.cummins.com https://quickserve.cummins.com/qs3/pubsys2/xml/en/tsb/2022/tsb220085.html 4/4
