Particulate matter, such as soot and ash, is presesnt in the Diesel Particulate Filter (DPF). The combination of oil residues with solid particles and water leads to the formation of sludge during the cleaning process.

In addition to soot, this sludgy ash comprises a complex blend of engine oil additives, metals from wear, products of corrosion, and other non-burnable substances.

This sludge accumulates on the surfaces of the filter cartridge pleats. The creation of sludge is reduced by a good filtration system. Furthermore, a special settling tank in the cleaning fluid tank of the Otomatic DPF cleaner helps prevent sludge build-up.

Otomatic filtration cartridges can prepare flushing fluid for around 50 DPFs, depending on the amount of sludge removed from the diesel particulate filters.

Disposed filter cartridges must be handled following the latest regulations. Always check with your local or state environmental authorities before disposal.
