Diesel particulate filter (DPF) mufflers on on-highway trucks capture ash and soot generated during the diesel combustion cycle and continuously combust the soot, leaving the ash to be dealt with. Consequently, these DPFs need to be cleaned periodically through their life cycle. Truck maintenance facilities can now purchase an efficient and cost-effective DPF cleaning system from Donaldson Co.

The Donaldson Pulse Cleaner is a self-contained system that dislodges diesel ash and soot from the DPF. The removed ash and soot are captured in a serviceable filter in the lower portion of the system's cabinet. The average cleaning cycle is 15 minutes or less, depending on the level of contamination.

For extremely plugged filters, Donaldson offers the DPF Thermal Regenerator, a specially designed unit that removes hydrocarbons and unburned soot through a timed heating and cooling cycle.
