How long does it take to clean a DPF filter

The answer to this question is that it depends on what method of DPF cleaning is being used. At Darwen Diesels, we offer a 24 hour turnover time for our DPF cleaning service. Each DPF is thoroughly cleaned using our Flash Cleaning Machine which flushes water through the DPF cleaning away soot and ash deposits until it is returned to an almost new state. Each time the DPF is flushed, a ‘back pressure’ report is produced. This shows how effective the cleaning cycle has been.

Importantly, the integrity of the DPF is maintained throughout the cleaning process. All sensors remain in place, and do not have to be removed.
