Diesel Particulate Filters has succesefully installed in cars, buses, trucks, and various construction machinery vehiles, DPF's life WITHIN the 300, 000km, collection efficiency range 97percent. Heat regeneration is made through the displacement management, and the ashes left from the regeneration shall be cleaned regularly. Systematic designs are available upon customers' requirements, so as to reach the demands of different displacement standards. Diesel particulate filter is made of cordierite or silicon carbide. It adopt opening and blocking up passages in both ends and the exhaust gas flow through the porous beehive wall to filter particles.

Low pressure drop
Excellent capturing performance
Low thermal expansion
High filter specific surface area
Long-term durability performance
High soot removal: > 95%
Diesel particulate filter is made of Sic, and it is used to remove black smoke (PM e. G.: Hydrocarbons, soot) from diesel engine exhaust. And usually DPF removes 95% or more of the soot. 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.

Features:
*Uses porous porcelain materials and porous sintered metal as filtration materials, which can filtrate the solid particles in the diesel displacement, thus meeting the exhaust particle requirements of the displacement laws and regulations
*According to the engine uses and operations, physical and chemical methods are adopted to eradicate the particles periodically, so that the displacement resistance can be maintained in a certain level and not influenced by the diesel performance
*The particle filtration efficiency of the diesel is more than 90%
*Heat regeneration is made through the displacement management, and the ashes left from the regeneration shall be cleaned regularly
*Systematic designs are available upon customers' requirements, so as to reach the demands of different displacement standards
Characteristic
*Large and compact area per unit volume
*Small pressure loss and excellent capturing performance
*Excellent heat resistance and heat shock resistance
