Honeycomb Ceramic DPF Filter Diesel Particulate Filter DPF DOC
DPF filter 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
Product Advantage:
High filtration efficiency
Low coefficient of thermal expansion (CTE)
Low thermal shock resistance
Low back pressure
Outstanding durability
Low pressure drop
