Donaldson Develops Two-Stage DPF Muffler Cleaning System

2/1/2007
Truck maintenance facilities can now purchase an efficient and cost-effective diesel particulate filter (DPF) cleaning system from Donaldson Co., a leading manufacturer of filter systems and replacement parts.
Compliance with the 2007 heavy-duty diesel engine emissions regulations has increased the use of DPF mufflers on on-highway trucks. DPFs capture the ash and soot generated during the diesel combustion cycle and continuously combust the soot leaving the ash to be dealt with.
Consequently, these DPFs will need to be cleaned periodically through their life cycle. 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 located in the lower portion of the system's cabinet for easy removal.
The average cleaning cycle is 15 minutes or less, depending on the level of contamination. For extremely plugged filters that require a more intense cleaning process, Donaldson offers the DPF Thermal Regenerator, a specially-designed unit that removes hydrocarbons and unburned soot through a timed heating and cooling cycle.
Donaldson's two-stage DPF cleaning system simplifies the routine cleaning, making it ideal for maintenance facilities responsible for servicing trucks equipped with diesel particulate filters.
For more information, visit the company's Emissions + Exhaust website at www.donaldsonexhaust.com or contact Donaldson at (866) 675-2847.


So it looks like these filters won't be too hard to service when needed.

it never was hard to clean them out .. but the cost to clean one will be high to offset the cost of the machine... also if any moisture goes thru the dpf it cant be cleaned and becomes junk.that is when the costly stuff happens . in the cummins dpf training it shows you all the criteria for a bad dpf and they can get loaded with oil fuel or coolant and be uncleanable or if they overheat and melt down they cant be saved. or if anything like an exploded turbo shoots pieces thru it and breaks the cores its also junk.

most engines equipped with these will have an automatic self clean system to clean them while driving by injecting fuel after the turbo to increase exhaust temps as normal usage. If they get to bad a shop with OE software can connect and put it thru a more indepth on unit clean procedure. with these functions you wont have to remove it to clean it unless it gets really plugged up

Read the bible Wayne! It goes through a regeneration process and injects fuel on the exhaust stroke to raise exhaust temps to 1000* plus and burn off the ash in the dpf. That is why the new super duty has the funny looking tip on the tailpipe to cool the exhaust coming out during the regen. process
