Partial-flow diesel particulate filter also known as PDPF, it is a non-blocking diesel particulate filter (DPF). Partial-flow filter with the catalyst coating is called POC (Particulate Oxidation Catalyst), it can be used in most diesel engine applications, but it requires diesel fuel with sulfur content less than 50 PPM for proper operation and works best with sulfur content less than 15 PPM (ULSD fuel).
Partial-flow filter uses a special alloy net weaving structure, and are coated catalyst, to collect and oxidize the particulate matter (PM) in the engine exhaust and to decrease the emission of CO and HC.
1. Reducing PM emissions by 50-80%.
2. Simple installation and operation.
3. No blockage or accumulate soot particles.
4. Requires no maintenance.
5. Low back pressure.
6. Improves sound attenuation, can replace original muffler.
