Diesel Particulate Filter
Diesel particulate filter is used to remove black smoke (PM e. G.: Hydrocarbons, soot) from diesel engine exhaust, being a great contribution to the environment because of dealing with the exhaust from diesel engines. The diesel particulate filter can be used in different industrial fields such as
Environment protection, petrol-chemistry, medicine manufacture, and metallurgy etc. It has good investment return and broad prospect. The system installed DPF (Diesel Particulate Filter) been examined for urban bus, forklift, truck & mining constructing equipment.
Characteristics:
*Broad band filtration (the diameters of the filtered particles are 0.2-150 µ M)
*Low back pressure
*High filtration efficiency (can be up to 70%-95%)
*High refractory
*High mechanical properties
