Why Clean a DPF?

A DPF (diesel particulate 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.

Filtertherm® is establishing THE industry standard for DPF cleaning.

Having the right equipment is only half the game.

The other key is the cleaning process. Establishing and following the same proven process with every filter is the best way to ensure consistent results. Without this consistency,  your results will vary from filter to filter.

The Filtertherm® team has spent close to 15 years cleaning tens of thousands of filters. We’ve fine-tuned and tested our methods in real-world cleaning facilities and we are happy to share them with you.


Educate your customers on DPF Cleaning

When you return the cleaned DPF and or re-install it on the customer vehicle, provide them the information they need for tracking and reporting. OE service recommendations are between 200,000 – 300,000 miles, or 4500 hours – whichever comes first. Aftermarket manufacturers of DPFs recommend cleaning at 50,000 – 70,000 miles, or 1,000 hours – whichever comes first.

Based on our experience, Filtertherm® recommends servicing your DPF at least once a year. Removing the soot more often will help extend the life and performance of the DPF system and your engine. Hardened ash build-up in the system restricts the flow and causes unnecessary engine failure issues.

Recommend a maintenance schedule that takes into consideration the real-world driving conditions of the vehicle. Trucks that are run in stop-and-go traffic or high idling situations often need dpf cleanings at closer intervals.

Proper DPF maintenance is key to a healthy truck.
