Aftertreatment System

AFTERTREATMENT SYSTEM REPAIR & MAINTENANCE

• Complete Routine DPF Cleanings: There are different stages of cleaning a DPF. Stage 1 is a pneumatic cleaning and involves removing ash and soot. Stage 2 is a thermal and pneumatic cleaning. The filter is baked to oxidize the soot and make the ash more pliable and easy to remove. This cleaning restores the vast majority of filters to their original state, so they’re ready for reinstallation. Stage 3 cleaning involves a thermal and pneumatic cleaning, as well as a wet wash, and is generally reserved for OEMs and large fleets to rescue highly contaminated filters. The depth of the cleaning process depends on the state of the filter, so it’s a good idea to keep up with regular cleanings.
