The basic attributes of a DPF

A diesel particle filter must grant two things: It has to filter the harmful diesel particles out of the exhaust gases, and it has to be able, by regeneration, to get rid of these particles. Filtration and Regeneration are, therefore, the two main functions of a DPF.

The Filtration is done by a special filter medium. The 25 years of experience of the HUSS Group has shown that a ceramic based filter medium made from Silicon Carbide (SiC) best fulfills these requirements. The combination of an excellent soot collection rate and low backpressure performance qualifies SiC to be a superior material for filtering soot particles - CDC considers it to be the best material available.

The advantages of the high-tech ceramic in an overview:

  • Excellent soot collection rate of 99.9% 
    Independent from the particle size and driving cycle
  • 200 cpsi cell density
    Balanced combination of stability and backpressure
  • Thermal stability
    Able to stand the exothermal reaction during the regeneration process; granting the filter a long life span
  • Thermal conductivity
    The filter is regenerated completely within a short time due to its homogeneous heat dispersion
  • Chemical resistance 
    Aggressive substances in the exhaust gases are not harmful to the filter material
