DPF Cleaning Service

A DPF physically traps and collects diesel soot and ash particles from diesel engine exhaust. While most of the trapped soot (organic matter) is burned off during periodic filter regeneration, metal oxide “ash” (inorganic matter) particles are not burned off. Ash is the inorganic material from lube oil and wear metals. It comes from the engine and is left behind after thermal filter regeneration. Over time, the unburned ash particles and soot will plug the filter unless the filter is periodically cleaned.
