DPF Cleaning, Air, Water? Whats the best method?

Huh, I thought everyone was baking the DPF's???

 

We send out DPFs all the time for cleaning. They are baked and cleaned with air pressure with one of those SPX machines. Great success. Installing a reman everytime is simply not cost effective. I don't buy the increased temps due to left over ash for the simple reason the temps don't increase normally when a DPF already has a higher ash content through normal use. Do you have any links about what you are claiming?

 

Most shop's by us are pressure washing them with a special clean product no one bakes any more does work. Do not use high pressure you will cut into the filter and do not waste the money on reman buy new less headaches more miles before it need to be done again. More guys are buying a new filter and getting back to work trying to save a buck will cost you more i down time and labor. Also change def filter and injector same time depending on your system.

 

We have 8 dd13's that range from 700,000 to over 900,000 ALWAYS baked and replaced, never an issue! To clean on of ours and reinstall is right at 1200.00 a new one is 4000.00 BIG difference, to me anyway?

 

We have done some exchanges, but the price I was quoting was installed.

 

Personally, I am waiting for the study to come out in 10 years about how the heated emissions from regens are causing some form of cancer that is much worse than no emissions would have been.
