How does a DPF Cleaning machine work?


Quick Answer

A DPF cleaning machine is designed to clean the diesel particulate filter, or ash or soot, that accumulates in a diesel particulate filter from a diesel engine's exhaust. According to Clean Diesel Specialists in Anaheim, Calif., their diesel particulate filter cleaning machine, known as the EvacuBlast, uses a differential test system to monitor cleaning during the process. Compressed air and vacuuming work in sequence to remove soot and ash.

According to Takeuchi Manufacturing, a maker of compact construction equipment, DPF cleaning removes around 98 percent of soot deposits in diesel particular filters.

As a result, a customer who owns an excavator or track loader reduces both repair and maintenance costs. Filters can be reused instead of replaced. Using a DPS machine lowers emissions as well. Takeuchi adds that filters should be routinely cleaned every 3,000 hours to keep a machine operational and working optimally.

DPFs are inspected for damages or cracks before they are cleaned, and filter tubes are examined after the cleaning is complete, according to Takeuchi. The site advises to make cleaning part of a preventive program of maintenance for skid steers, track loaders, wheel loaders and excavators.

Truck News.com says that DPF cleaning machines are still not used a great deal in trucking companies. Bison Transport in Mississauga, Ontario, believes it is among one of the first fleets to own the machine. According to the news site, the company plans to set up a preventative maintenance program for its fleet of trucks.
