PN reduction, % PN redction, % Why choose Dinex DiSiC HP ? 1. Filtration Efficiency The filtration efficiency at different soot load levels is shown on these diagrams. Already in the first test cycle on the test bench, a fresh unconditioned filter has a filtration efficiency of 98% and the soot loaded filter always shows more than 99% efficiency tested at different exhaust flow rates. Median Pore Diameter, μm: 8 – 9Inl Dinex DiSiC HP (Gen. III) has a very low median pore diameter, thanks to the unique pore structure. Competing technologies: 9,0-11,0 μm Porosity by MIP test, %: 54-57 Low pore size combined with high porosity, Dinex DiSiC HP delivers high PN Filtration efficiency (>98%) starting from fresh condition.

Back Pressure The low back pressure fresh and under soot load in comparison to a standard SiC filter from the market is shown in these diagrams. The high porosity leads to the lowest back pressure compared to other market products and the surface filtration caused by the unique pore structure ensures that this difference is kept also under soot loading. Wall Thickness, μm: 300 Thicker walls support higher soot load capacity, allowing for extended regeneration intervals, but affect back pressure negatively… Competing technologies: 180-280 μm Porosity by MIP test, %: 54-57 … but thanks to the high porosity,the back pressure of Dinex’ DiSiC HP remains comparable.
