Product Description Product DescriptionDPF 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 Our AdvantagesHigh filtration efficiencyLow coefficient of thermal expansion (CTE) Low thermal shock resistanceLow back pressureOutstanding durabilityLow pressure drop Cordierite Diesel Particulate Filter(DPF)Cordierite material, which is raw material molding and synthesized cordierite after burning, cordierite DPF filters are one of the most viable solutions available for use today.The most common filter is made of cordierite. 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.

The carbon smoke particulate is absorbed to the filter made of metallic fiber felt, when passing the inner dense set and bag-style filter. When particulate absorption reaches some degree, the tail burner would be ignited to burn automatically. In this case, the particulate absorbed been burned out and turned into nontoxic CO2 then discharge. The full device is designed as double room structure, and filtration and recycle are going in different areas, making them non-disturbed. The system can work automatically whatever working condition the engine in. Especially made honeycomb ceramic particulate filter, acts as capturing device to the particulate to some extent.Product ApplicationDPF can be widely used in different industrial fields such as transportation, generating units, engineering machinery and metallurgy etcPackaging & Shipping
