DPF Cleaning

Diesel Particulate Filters accumulate ash residue that builds up over time but Mammoth's DPF cleaning technology uses ultrasonic technology to restore any and all DPF filters that others can't.

How it works

Air Knife

Our base air-only service provides an environmentally-safe and competitively priced solution for moderately clogged filters. We start every Ultrasonic Cleaning with this step to remove any loose debris.

Advanced Regen

Known as "bake", our stage 2 advanced-regen bake service is commonly combined with the Air Knife process. This is an excellent option for regularly maintaining your filter.

Solution Flush

Our stage 3 service sets Mammoth apart from other cleaning companies. Combined with the previous stages and a 6-month warranty, this stage should be the minimum level of cleaning for any filter.

Ultrasonic

Our ultimate, industry-leading Ultrasonic Cleaning allows us to offer you a lifetime guarantee on the useful life of your filter. After extensive process refinement and testing, we have developed an unmatched clean for filters in every industry. Our process will bring any functioning filter back to as much as 98% of its useful life.

DPF Installation

Intro to DPFs

Diesel Particulate Filters are an emission control device meant to capture and store the soot from diesel engines, reducing the emissions of pollutants released.

What is DPM?

Diesel particulate matter is a byproduct of an operating diesel engine. Find out why this harmful particulate needs to be taken care of.

What does a Back Pressure Monitor kit do?

Find out how the pressure level in a DPF can be measured with this kit.

What are the 3 parts of a DPF?

Watch our explanation on the three parts of a DPF:

  • the DOC
  • the filter section
  • the outlet/tailpipe

Common Questions

See some common questions and answers below, or call us at 800.854.8291
  • What is Ultrasonic?

    Ultrasounds are sound waves with frequencies above the human auditory range (20 – 100 kHz). The ultrasound applications are based on the physical phenomenon of cavitation which may be induced in any liquid medium. The sound waves cause the microscopic bubbles present in the natural liquids to expand (during phases C and D of high pressure). The formation and implosion of bubbles (cavitation process) is produced thousands of times per second.

  • Can all DPF's be cleaned with ultrasonic technology?

    Yes

  • Can you clean "irrecoverable" DPFs?

    Yes, there has been many instances where we have been able to restore filters that other service centers with traditional cleaning equipment claimed were irrecoverable.

  • Do you have an exchange program?

    This program is being developed and we hope to have available very soon for some of the very popular filters.

  • Do you pick up DPFs?

    Yes we do. Contact our team for more information

  • Do you have a DPF removal/installation service?

    We would like to offer this service however space does not permit at this time.

  • Why do filters need cleaning?

    1. Though the process of continual thermal cycling in the DPF (Regeneration), with each soot burn off there is a residue of inert ash.   When this gets mixed with humidity and heat from the exhaust this ash gets baked and impacted into the filter.   Over a period of time, by performing the simple ‘pin test’, it will be found that the filter is filling and back pressure is increasing


    2. There has not been sufficient regeneration and the filter has become plugged with soot


  • Do I need to clean my DOC's?

    Yes – Periodic cleaning of DOC’s required otherwise these can become soot loaded and their effectiveness compromised – especially if the DOC has been exposed to high-sulfur and poisoned.


  • What is Ultrasonic Technology?

    Ultrasounds are sound waves with frequencies above the human auditory range (20-100 kHz). The ultrasound applications are based on the physical phenomenon of cavitation which may be in any liquid medium.


    The sound waves cause the microscopic bubbles present in the natural liquids to expand (during phases A and B of low pressure) and contract until they implode (during phases C and D of high pressure). The formation and implosion of bubbles (cavitation process) is produced thousands of times per second.

  • Why is ultrasonic cleaning better than traditional cleaning?

    Ultrasonic cleaning is required to break down the impacted ash residue that traditional high temperature baking and air blasting could not break down. Where traditional cleaning could typically only get the filter 65-70% clean, with ultrasonics we can restore the filter to 98% clean.

  • How do I tell how clean my DPF is after cleaning?

    Combination of flow test and pin test.   With the Pin test, a thin wire is inserted into the clean side of the filter and a measurement taken.  The Pin is then inserted into the ‘dirty’ side of the filter and a 2nd measurement taken. If the filter has been properly cleaned/restored then the 2 measurements should be equal.


  • What size DPFs can be cleaned?

    Our equipment is big enough to clean all known DPF sizes.

  • How long does it take to clean my DPF?

    Typically 24 hours.  A high speed cleaning program is being developed, watch this space!  There is the occasional filter that is very highly impacted and additional time is required.

  • Where are your cleaning locations?

    Calgary, Alberta

    Edmonton, Alberta

    Montreal, Quebec

    Ottawa, Ontario

    Toronto, Ontario

    Winnipeg, Manitoba


  • What happens if my DPF is covered in sensors?

    Not a problem.  There is an additional charge for removal of sensors.  While we seek to be able to reuse these sensors, they are very sensitive and sometimes require replacing.  The DPF Company can supply these with your restored filter.

  • Will cleaning DOC's with ultrasonic effect the wash coat?

    No – study by Tech Sonic International showed no loss in weight of filter/DOC as a result of cleaning
