Metal fiber media for diesel exhaust filtration

Metal fiber media for diesel exhaust filtration

Sintered and unsintered metal fiber non-wovens on basis of an AISI 47… alloy.  Thanks to well balanced combinations of fiber weight, fiber diameter and porosity, those filter media can achieve mass efficiencies in between 30% up to 90%. Because of the availability of cleaner engines (pre-EURO VI), a lower mass efficiency (<90%)  filter can do the job.


  • Tunable mass efficiency compared to ceramic diesel particulater filters (DPF), enabling the engine OEM to fulfill the legislation with the lowest pressure drop
  • High efficiency for small pulmonary intruding particulates
  • Design freedom & flexibility
  • Lower pressure drop resulting in lower fuel consumption and lower CO² emission


Exhaust systems Filtration
Partial flow deepbed filter for trucks
Partial flow deepbed filter for heavy duty off road
Closed filter for off road equipment


Type Media
