What is DPF?
DPF (diesel particulate filter) treats your truck's exhaust by trapping particulate matter which is basically soot and ash. Diesel particulate filters have been a crucial part of a truck's emissions system. DPF's capture approximately 90% of diesel particles and soot preventing them from being released through the exhaust system.

DPF particulate filter

Benefits of a clean DPF include:

  • Improved vehicle performance
  • Increased fuel economy
  • Experience fewer regenerations
  • Lover maintenance costs
  • Extended DPF life

Cleaning

The DPF must be cleaned every 150,000 to 300,000 miles to remove the built up ash. The filter should also be cleaned if a fuel injector or turbo problem causes contamination with engine oil or non-combusted diesel. This contamination cause unwanted back pressure. Cleaning methods include air blasting, de-ionized water and a vacuum-like system. This must be done very carefully to avoid any damage to the filter. The particulate matter that is removed must be handled with extreme caution to ensure there is no exposure to the very fine contaminants.

DPF and Preventative Maintenance

The DPF is yet another component that must be tracked and maintained on a heavy duty truck. Ensuring regular preventative maintenance is performed on the DPF will do wonders in ensuring the long life of the DPF. Replacing air filters and fuel filters regularly along with using the correct type of oil for the engine will help prevent any unnecessary wear and potential damage with the DPF.

Very nice and friendly, I went in, told them what was wrong with my tractor. They looked at it and told me exactly what was wrong and gave me a time frame on how long it will take them to repair it. The truck was done within the time they told me, I paid them and was on my way.

So I have been to a lot of shops over the past year and a half since becoming a owner operator. I just want to say this place is the most fair and honest place I’ve experienced. Nikki was so nice and had her start on my trailer right away. She jumped in to help, and she tracked down a grounded out wire. She knows what she is doing. I had a Speedco shop try to figure it out first but that was a waste of time. Once I read the reviews of this place I knew I had to try them. The amount of time I saved by stopping in at Specialized truck repair saved me a lot of money. Thank you Nikki! You are a prime example for how a shop should run.So I have been to a lot of shops over the past year and a half since becoming a owner operator.
