Model DPF -wall-flow Diesel Particulate Filters

Our diesel particulate filters utilize Advanced Cordierite or Aluminum Titanate wall-flow monoliths to trap the soot produced by diesel engines. The cylindrical filter element consists of many square parallel channels running in the axial direction, separated by thin porous walls. The channels are open at one end, but plugged at the other. This way the particle laden exhaust gases are forced to flow through the walls. Gas is able to escape through the pores in the wall material. Particulates, however, are too large to escape and are trapped in the filter walls.
