DPF is a device designed to remove diesel particulate matter or soot from the exhaust gas of diesel engine vehicles.The DPF filters first trap particulates and then use a catalytic technology to continuously burn them at normal diesel operating exhaust temperatures.
DPF Filters are one kind of wall-flow monolith, the channels are open at one side, but plugged at the other. it will be installed in the diesel car exhaust system, to reduce particulate matters (PM) of exhaust by trapped. The main components of Diesel engine exhaust are particulate matter(PM), carbon monoxide(CO) and hydrocarbons(HC), Diesel Particulate Filters Can reduce them by 90+% from diesel engines
With the development ,the goverment have higher request for the tail gas emission standard,so we can provide the coating DPF ,PT ,PD ,RH as per your request ,in normal is Euro iv v vi .
Meantime ,as per the different market ,we produce cordierite materila and silicon carbide material for your choose ,below is the detail data
Physical & Chemical Properties of Cordierite Diesel Particulate Filter
Cordierite filters provide excellent filtration efficiency, are relatively inexpensive (comparison with Sic wall flow filter). The major drawback is that cordierite has a relatively low melting point.

Physical & Chemical Properties of Silicon carbide Diesel Particulate Filter
Silicon carbide diesel particulate filters (Sic wall flow filters) have a higher melting point and filtration efficiency (can be up to 95%) than cordierite, they are usually more expensive than cordierite wall flow filters.
