High Performance Doc+DPF Diesel Particulate Filter for Car
This product can be directly oxidized and decomposed the diesel engine exhaust particulate matter (PM). Compared to the conventional platinum catalyst , since the NOx catalyst without passing through the DOC conversion NO₂, thus reducing the amount of expensive platinum, lower cost, and can obtain the same decomposition performance at lower temperatures, and in temperature can be increased at the same rate of decomposition. It can also improve the combustion performance to the number of PM 's calculations , can reach more than 90% removal efficiency. Sanhe DPF and DOC units are proudly designed and manufactured , backed by outstanding warranty coverage and meet all Euro emissions standards. 

1. Ceramic DOC technology with Zeolites designed to extend the performance of diesel catalytic converters into the low temperature range
2. Maintenance-free, reliable and cost-effective emission control solution
3. Available in both universal and direct-fit designs 
4. Mufflers are built entirely from corrosion resistant materials: aluminized and stainless steels
5. Installation time and cost are reduced to a minimum
6. DOC Catalytic Mufflers match or surpass the original muffler in sound attenuation and back pressure characteristics with addition of superior emissions performance
7. Great at reducing deadly emissions,such as Carbon Monoxide(CO) and Hydrocarbons(HC)
