Cleaning the DPF (diesel particulate filter) is critical for keeping large trucks mobile, and the truth is that it isn't an especially difficult or messy task. The majority of DPFs being used these days may be cleaned in under an hour. The procedure is mainly automated, and plenty of Clean DPF Filter tools exist in the marketplace.
Properly cleaning a DPF and its related components during PM (preventive maintenance) stops boosts the filter's life span, helps to keep the engine operating cleanly and decreases potential malfunction threats. The majority of heavy-duty DPFs need to be cleaned between 200,000 and 250,000 miles.
As most high-tech DPF cleaning support companies will attest to, the initial phase in cleaning a DPF is to examine the filtration system housing and its associated components for damage or deterioration. A DPF that is well taken care of may survive numerous cleanings, but the system has to function at 100 percent in order to be efficient. Many technicians believe a DPF ought to be examined and confirmed as acceptable for re-use prior to cleaning. Any DPF that is discovered to be functioning improperly needs to be replaced.
Following the visual examination of the DPF, it may be taken off of a truck or tractor and connected to a filter cleaner to commence the procedure of eliminating grime and dirt from inside of it. Many companies recommend that the filters be cleaned with a FSX tool, which demands that the filter be taken off of the truck or tractor and inserted onto the device for cleaning. Applying the correct technique is absolutely essential. Insufficient cleaning and upkeep of the DPF can result in more regularly occurring system regenerations, and that will end up shortening the life span of the DPF along with the filtration system in its entirety.
As soon as a mechanic has learned what cleaning method the DPF calls for, he just needs to attach the DPF to the cleaning equipment and begin the procedure. A standard means for DPF cleaning is to apply high-pressure air through the DPF in a round, sharp snaking motion to loosen the particulate from the filter walls and expel it out through the end. This technique dislodges the dirt and ash from the DPF swiftly and effectively. The particulate is then transferred into a different container for quick disposal.
During the DPF cleaning, a mechanic should also examine its associated parts, such as the tank filling arm and the diesel exhaust fluid pump filter. Both of these components have shorter suggested service periods than a DPF, so it is highly advisable for technicians to examine and clean both parts during the DPF cleaning.
The next phase following the completion of the cleaner cycle is to examine the interior of the DPF in order to be certain that the cleaning was effective. The FSX cleaners that most companies, like Anosonics.com, advise using come with air flow tests which test the filter both prior to and after its cleaning to discover if there's any back pressure from soot build-up. A DPF that tests out well can be re-installed immediately on the truck, whereas a test failure indicates that the DPF needs to be cleaned again in the device or with thermal cleaning.
Thermal cleaning is a more advanced means of cleaning that operates by putting a DPF in a heat chamber at a high temperature, which ultimately loosens and eliminates excessive particulate that is crusted onto the walls of the filter. Also referred to as filter “baking," thermal cleaning is employed if the on-site cleanings have failed.
