Product Details  DPF is used to remove the PM from diesel engines.  Diesel particulate filter is made of SiC, the ceramic material can meet the Euro IV and Euro V standards. And usually, DPF removes 85% even more of the diesel particulate matter and the soot, including ultra small particles, and the filtration efficiency can even arrive Euro V. In addition, it can be used widely in industry and military aviation fields for exhaust and black smoke treatment. Working principle Inside is a honeycomb ceramic structure designed to filter the exhaust gases while minimising flow reduction. By forcing the exhaust gases through the walls between the channels of the DPF, the particulate matter is deposited into the channels, after the proper ways of regeneration to burn the PM and soots to get the clean air from the polluted exhaust gas.
