Particulate matter, such as soot and ash, is noticeable 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 sludge catcher in the cleaning fluid tank of the Otomatic DPF cleaner helps prevent sludge build-up.

Otomatic cartridges can clean up to 50 DPFs, depending on how much sludge is taken out 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.
