Diesel Particulate Filter (DPF) , also called wall flow filter,is suitable for exhaust gas purification of various kinds of diesel vehicles and ships. We can produce different materials of DPF: cordierite particulate filter and silicon carbide diesel particulate filter .We also supply Catalytic Converter, Catalytic muffler, Motorcycle catalytic converter, DOC Catalyst, SCR catalyst ,Ceramic honeycomb monolith , Metal honeycomb carrier, ect. Our management system has been certified the ISO9001 and TS16949 by SGS company.
 
 
Materials: cordierite or silicon carbide
Function:
Wall-flow diesel particulate filters usually remove 95% or more of the soot, and under certain conditions can attain soot removal efficiencies approaching 100%
 
Working Principle
By forcing the exhaust gases through the walls between the channels of the DPF,the particulate matter is deposited on the walls ,so reducing the amount of air pollution.
 
 
Silicon Carbide Diesel Particulate Filter
 
The second most popular filter material is silicon carbide is a ceramic compound of silicon and carbon , also called SiC. It has a higher melting point (1500ºC) than cordierite.
 
SiC cores are usually more expensive than cordierite cores, however they are manufactured in similar sizes, and one can often be used to replace the other.
