International Leaders in DPF Cleaning

What are Diesel Particulate Filters (DPFs)?

Diesel Particulate Filters (DPFs) remove particulate matter, such as soot and ash, from diesel engine exhausts.  Because of stringent international emissions regulations DPFs are being fitted to more and more trucks, buses and cars.  DPFs are also known as ‘particulate traps’ and consist of numerous small channels in a porous ceramic material. 

When the exhaust gas passes through the filter’s inlet channels it is forced through the porous walls of the filter, before emerging from the outlet channels. The particulate matter is then trapped when the exhaust passes through these channel walls, removing up to 99% of the particulate matter in the exhaust fumes.


DPFs come in lots of different sizes as well as a variety of ceramic materials, including: 

  • Silicon Carbide
  • Cordierite
  • Aluminium Titanate

You’ll usually find that DPFs in cars are enclosed in a metal can close to the catalytic converter, while the DPFs in trucks are usually cylindrical and the filter can clearly be seen from either end.

Our patented Xpurge® cleaning technology has been subjected to rigorous testing to ensure that successfully clean all these types of filters.
