Frequently Asked Questions

It is important to have your DPF cleaned as recommended by the manufacturer of your vehicle to ensure your aftertreatment system continues to operate smoothly. If maintenance on the DPF is ignored, it can cause expensive and unexpected downtime.

If you are experiencing excessive regeneration, or your unit feels sluggish or low on power? This is an indication that your aftertreatment filters may be plugged and need to be cleaned.

DPF’s, DOC’s, SCR’s and EGR’s can all be cleaned. Contact us today!

It will depend on what the manufacturer requires or recommends and will also depend on how your equipment is being used (highway driving differs hugely from city driving).

With our Gold Restoration Service, your DPF will go through an extra step - what is known as the ultrasonic step. The Gold Service takes more time with the ultrasonic step vs. the traditional clean (blast and bake) and it is well worth paying the extra because it restores your filter to like new condition. Remember, if we can't clean it, you don't pay!

Yes, we can clean your SCR (Selective Catalytic Reduction) filter on our Silver Service which restores it back to 80 to 85% and includes a 6-month warranty.

Our Silver Service - $339

Please be aware there is no way for us to test the SCR. We do not recommend using our Gold Service on your SCR because it would ruin the precious metals in your SCR and it would no longer perform correctly.

We believe a thorough DPF inspection involves a visual inspection, flow test, pin test and light test to ensure DPF filter integrity and that the filter has been returned as close as possible to its original factory condition.

The typical cycling of regens will be continuously leaving an ash residue in the filter. This ash mixed with the heat and moisture from the exhaust will bake that ash into the filter. While traditional blast and bake methods of cleaning are effective at removing some of this material, it can often become heavily impacted if the filter has not been cleaned regularly. Through extensive research and experience we have found that ultrasonic technology combined with a pneumatic aqueous flush followed by kiln drying is the most effective way as restoring the DPF to 98% of its original condition.

If your filter has been restored using our Gold Service, it should perform as well as a new filter. Our Gold Service will restore your filter to like new condition meaning that it should last as long as a new filter.

Our Gold Service is the best and most recommended process for DPF Cleaning. The 4 step Gold Service Restoration process includes an extra step known as ultrasonic restoration which will restore your DPF filter to like new condition, up to 98% of OE specifications and comes with a twelve-month warranty. Ultrasonic Restoration is, by far, the best industry leading DPF cleaning practice that includes a guarantee clean and a one-year warranty for diesel particulate filters.

We offer pick up and delivery service to our customers. This could be through our team or via courier depending on your location.

The pricing range between these two options will be very significant.

A DPF Restoration on our Gold Service is $489.

A new replacement DPF cost will depend on what kind of vehicle you have however it will most likely cost you thousands of dollars.

Soot and/or ash that is removed from filters during the cleaning is collected in our dust collection units and disposed of in accordance with government regulations in each local jurisdiction. Where possible we recycle/reuse any waste by-products to reduce the environmental impact diesel engines have on the environment.

Rule of thumb is, if the truck is doing multiple regens (4+ per week), there is a high chance your DOC needs replacing. We cannot test DOC’s ourselves however if you notice your vehicle doing multiple regenerations in a short period of time, this usually means precious metals are no longer working.

EGR’s are known to get very plugged and at The DPF Company, we will run your EGR through our Gold Service two times if required to clean out as much debris as possible. When we do this, we only charge for one clean, not two even though we do run it through two times. Please be aware that we do not have a way to test EGR’s.

It will depend on what the manufacturer requires or recommends and will also depend on how your equipment is being used (highway driving differs hugely from city driving).

With your Gold Service, your filter is restored with four different steps including ultrasonic cleaning.

While the initial unit cost is higher, check out the difference in cost over the life of the filter!

You only pay when your DPF filter passes. There are no cleaning costs for any failed DPF filters.

Gold service includes a 12-month warranty.

Removing the DPF from your aftertreatment system can be a legal issue depending on where you are from. In some Canadian provinces, it is mandatory to have a DPF filter as a part of your aftertreatment system. Having your filters removed or “deleted” could lead to unexpected charges.

Typically, 24 hours. We offer a rush service if you require. Contact our team to find out more.

The Ultrasonic Restoration should last as long as a new DPF filter. The Gold service will restore your filter to like-new condition.

Regular cleaning or also known as blast & bake cleaning will clean a filter without doing the ultrasonic step, meaning there could still be some debris left in your filter and that it will clog up faster.

Regular engine maintenance is largely the biggest factor in ensuring the best performance from the DPF. Restriction from dirty air filters, worn components etc. are all factors that will increase soot loading of the DPF. Low-ash engine oils are always a recommendation as they lower the residual ash deposit in the DPF through the regen process. There are some newer products on the market today that are known as FBC (Fuel Borne Catalyst) that significantly improve engine combustion and lower soot loading of the DPF.

Delaying regen is never a good idea. The results typically are sustained higher back pressure. This will cause accelerated wear on the turbo seals, valves and increase the risk of fracturing/cracking in the DPF filter. Sustained high levels of soot loading will also increase the risk of uncontrolled regen or DPF melt-down which will obviously destroy the DPF.

Primarily we see oil leaks poisoning and deactivating the precious metal coatings of the DOC. This then reduces the DOC’s ability to convert gases and the DPF’s ability to regenerate the soot into ash, thus driving up the need for active regens.

DPF service life can be limited by coolant and oil leaks, failing fuel injectors, and even dust in an air intake.

The DPF service life can be limited several ways, we would recommend a mechanic should look at the coolant, look for oil leaks, failing fuel injectors and even dust in the air intake system.

There are many factors at play here. Drivers in general are familiar with regular periodic replacement of their air filters, oil filters etc. Unfortunately, it is accepted practice in the industry that you wait until you get warning lights on the dashboard before servicing the DPF. We would highly recommend operators review the work cycle of their vehicle (City Truck vs Highway Truck) and schedule DPF cleaning into the preventative maintenance schedule.

Yes, see answer above. We believe that regular cleaning and servicing of the DPF filter does extend the overall life of the filter, will reduce the risk of filter failure, and will lower the risk of other engine component failure because of lower overall back pressure.
