Particulate Filter Systems

The Purifier™ family of particulate filter systems provide a complete range of particulate matter solutions while improving fuel economy. The patented Purifier solutions combines filter hardware with fuel borne catalysts to allow for operation in a greater range than traditional filter solutions, especially at low temperature applications.

Purifier family of highly efficient PM control systems:

    Purifier System
Reduction in emissions
    PM NOx NO2 CO2
Purifier™ e4
  • Diesel Particulate Filter (DPF)-based emission control system providing the highest level of PM reduction without an increase in NO2
  • Reduced DPF regeneration temperature expands the applications in which a passive DPF can be employed
  • Minimizes unscheduled maintenance and lowers overall operating costs
 Reduction
99%+A		 Reduction 9%A No increase 0%A Reduction
5-8%C
Purifier™ e3
  • Partial filter emission control system based on our Catalyzed Wire Mesh Filter (CWMF)
  • Best Available Control Technology for low-temperature applications where a DPF is not feasible
  • Low NOx solution with no NO2 increase
  • Passive solution with low maintenance requirements
 Reduction
76%B		 Reduction 9%B No increase 0% Reduction
5-8%C
Purifier™ e2
  • For high soot applications where neither DPFs nor partial filter solutions are applicable
  • Higher PM reduction than traditional diesel oxidation catalyst (DOC) with no increase in NO2
