DPFs are quickly becoming popular for their pocket emptying powers. Truly, the replacement cost for a DPF is high, and frequent replacement of a DPF is a burden on the wallet. So, what should one do to save themselves from investing in a new DPF? The answer is simple – properly and periodically clean your vehicle’s DPF. Regular cleaning of a diesel particulate filter can help in keeping the DPF in optimum condition and ensure its longevity.
DPFs trap soot from the exhaust and ash from motor oil. No doubt, most soot is burned off in the course of a vehicle’s operations, but ash does stay in the filter’s honeycomb substrate until it is removed through periodic servicing.
Why Cleaning the DPFs for a Cheap Price Does More Harm Than Good?
Due to the requirement of frequent cleaning of DPFs, unfortunately, some diesel vehicle owners are pouncing on rock-bottom priced cleaning service without hesitation. Many people are taking out the DPFs from their vehicles and bringing them to a car service centre in order to blow them out with the air compressor or clean them out with water. But these diesel car owners have forgotten that most of the times a cheap price equates to cheap quality service.
Water in a DPF can set the soot/ash into concrete like substance, which will, in turn, ruin the DPF completely. Moreover, high-pressure water damages the cells inside the DPF. Ash removal through compressed air is not enough too. Per say, such a procedure for diesel cleaning service does more harm than good!
- DPF cleaning necessitates heating the filter, utilising compressed air combined with a vacuum system to remove the ash, and bagging it in an airtight container.
- Filter cleaning processes approved by the DPF manufacturer must be used.
- A wrong cleaning method can destroy the filter and/or expose staffs to harmful trash.
- To clean the DPF, shop compressor in an open area must not be used.
- Avoid steam cleaning the DPF.
- Never rap on the filter element to blow out ash.
- DPF cleaning service providers must employ the right procedure and handle ash in a proper manner.
- Filter elements must be installed right after they are cleaned. The filter elements should not be upturned.
- Do not operate the engine sans the filter elements.
- Service records must be maintained.
Why Professional Cleaning is the Proper Way to Clean DPFs?
Whether you have a light, medium or heavy-duty diesel vehicle, professional cleaning of DPFs is the only long term solution for DPF problems other than an expensive replacement. A proper professional cleaning service for your vehicle’s DPF is crucial to bring your filter back to a nearly new condition without damaging the filter, the environment and the personnel.
Professional 7-step cleaning service is the ideal type of cleaning for your DPFs. The process is as follows:
1. Weighed Dirty- To make a report to be later compared with the cleaned unit
2. Dirty Flow Test- To determine how dirty the flow of the filter is before cleaning
3. The Bake- To safely burn soot and ash without damaging the filter
4. The Blast Cabinet – To clearly see when the DPF is ash-free and put extra efforts on the dirtier areas
5. Visual Inspection – To look for possible internal fractures or damage
6. Clean Flow Test – To compare the flow to previous restricted flow
7. Weighed Clean – To show how much soot/ash has been removed
Switch to a highly cost-effective and eco-friendly DPF cleaning solution rather than settling for a very cheap DPF cleaning service that actually ruins your DPF.
Concluding Tip: Once the DPF is clean, it is important to make sure that carbon production remains at a manageable level so as to give the DPF a much easier life and save it from becoming oversaturated in the near future.
