Cordierite DPF Substrate
An economic porous wall flow type ceramic filter made from modified cordierite (2MgO-Al2O3-5SiO2) for diesel particulate matter removal.
Cordierite DPF Substrate
Product Overview
An economic porous wall flow type ceramic filter is also available for diesel particulate matter removal called diesel particulate filter. Such a ceramic filter is made from modified cordierite (2MgO-Al2O3-5SiO2). Current our DPF series has both 100 and 200 cpsi option and size is from 1.0 liters to 43 liters.
PRUITING® DPFs enable highly efficient particulate matter trap systems by offering:
- Low thermal expansion
- High filter specific surface area
- Low pressure drop
- Long-term durability performance
- High soot removal: >95%
- Excellent thermal shock resistance

FAQ
Cordierite DPF Substrate FAQ
What is the filter made from?
It is a porous wall flow type ceramic filter made from modified cordierite (2MgO-Al2O3-5SiO2).
Which cell densities and sizes are available?
The DPF series has both 100 and 200 CPSI options, and size is from 1.0 liters to 43 liters.
What soot removal can be expected?
The published performance for our cordierite DPFs is high soot removal above 95 percent.
Which shapes are listed?
The specification table covers round, oval and racetrack bodies, with volume given in liters for each dimension.
What is the difference between cordierite and SiC DPF?
The cordierite filter is the economic wall flow option. The SiC diesel particulate filter is a separate PRT product with carbon particulate filtration efficiency of more than 90 percent.
