Why do DPFs need to be cleaned?

A DPF (diesel particulate filter) filter is designed to catch & oxidize soot (unburned fuel/lube oil) and turn it into ash. The ash is pushed to the bottom of the filter and stored there. Over time it builds up and requires cleaning. With the cost of some new DPFs soaring to over $12,000, routine maintenance is key in all aspects of the DPF. Being proactive in your service intervals will decrease downtime, service expenses and increase proper system operation and profit. Thus, it’s important to regularly clean and maintain your filters, not only to preserve the functionality of the filter but to save on fuel and protect your engine.

OEM Regeneration

In a perfect world, OEM Filters perform their regeneration cycles on the truck. But we don’t live in a perfect world. Excessive idling, cold & severe duty cycles, even a broken exhaust pipe can inhibit regeneration on the truck. Most O.E. do not require thermal oven regeneration as part of their filter's service interval; but history has proven de-ashing alone will not deliver consistent results when cleaning your DPFs. Also, all leading after-market manufacturers require a backing cycle in addition to de-ashing to properly clean their systems.
