New DPF cleaning service


Volvo Truck and Bus Dealership Irish Commercials has launched its new Diesel Particulate Filter (DPF) cleaning service.

Using state-of-the-art equipment to thoroughly and completely clean HGV diesel particulate filters, it reduces vehicle downtime, increases fuel economy and significantly protects against DPF failure.

DPF’s are designed to remove particulate matter in the diesel exhaust. However, over time – even in a correctly operating vehicle – deposits of soot and ash captured in the DPF increase the backpressure on the engine, eventually reducing the fuel efficiency. Most engine manufactures recommend removing the DPF for cleaning from 160,000 kilometres, however research and testing has found that sometimes ash begins hardening in the filter cells as early as 100,000 kilometres. Once ash hardens it can cause permanent damage and cracking, so, thorough removal of this ash is essential for the operating efficiency of the engine as well as optimising the length of time between service intervals.

Testing
Testing is the first stage in the process and is done on the FSX TrapTester, an airflow test bench that measures the amount of resistance the DPF has to airflow through the filter. As a DPF fills up with dust it creates additional resistance to airflow, thus increasing backpressure on the engine. This measurement is the basis for determining the effectiveness of the cleaning engine process.

Pneumatic cleaning
The FSX TrapBlaster is the primary method of removing the accumulated ash and soot from the DPF, where it is subjected to high pressure scanning air jets on both ends of the filter. This process individually targets each of the many cells of the filter to remove as much dust as possible.

Thermal cleaning
The FSX TrapBurner heats the DPF to oxidise any soot trapped in the filter and loosens ash deposits. This process also removes oil residue from the filter which would interfere with the pneumatic cleaning process. Although the thermal cleaning process is not necessary for every filter, proper employment of the inspection and testing processes will determine if the thermal cleaning process is required.

Both the FSX equipment and cleaning process has been tested and approved by major OEMs as the equipment as it will NOT damage ceramic substrate or catalysed wash-coats.

The state-of-the-art cleaning equipment is also the recommended cleaning package globally for Volvo Truck and Bus DPFs.

How it works

  1. Stage 1 – Testing/ Inspection. An airflow test bench is carried out to measure the amount of resistance the DPF airflow through the filter. This measurement is the basis for determining the type of cleaning process.
  2. Stage 2 – Trap Blaster Pneumatic Cleaning. The DPF is subjected to high pressure scanning air jets on both ends of the filter. This process individually targets each of the many cells of the filter to remove as much dust as possible.
  3. Stage 3 – Trap Burner Oven for Deep Cleanse. The FSX TrapBurner heats the DPF to oxidise any soot trapped in the filter and loosens ash deposits. The thermal cleaning process is not necessary for every filter. Proper employment of the inspection and testing processes will determine when the thermal cleaning process is required.

How much and how long does the process take?
To use the DPF cleaning process, simply drop your filter into our Naas or Galway depot before 2:00pm and we will return it to you – free of charge – within 24 hours (weekends may take longer).

Stage 1 & 2 €330 DPF returned free of charge within 24 hours (weekends may
take longer)
Due to the effectiveness of our pneumatic cleaning programme, only 1 in every 8 filters will require a thermal regeneration to burn off any remaining soot deeply set in the ceramic cell walls (stage 3).

Stage 1, 2 & 3 €390 Return free of charge within 48 hours (weekends may take
longer)
