Sic/Cordierite DPF(diesel particles filter)

As one of the leading diesel particulate filter manufacturers, Huanlian Catalyst offers a wide range of reliable diesel engine particulate filter to meet the diverse needs of diesel engine applications. You can refer to the following detailed information to choose the best catalyzed DPF to extend the engine life. If you require a filter with special specifications, we also can customize the products tailored to your needs.

DPF (Diesel Particulate Filter)

• Product Name: Diesel Particulate Filter (DPF)

• Material: Cordierite, SiC

• Shape: Round, square

• Size: can be customized

• Cell Density: 100/200/300/350 CPSI

• Application: Diesel engine exhaust system

• Model: universal

• Emission Standard: Euro 4, Euro 5, Euro 6

【Efficient Wall-Flow Filtration】Both SIC DPF and cordierite DPF are designed with a wall-flow honeycomb structure, trapping over 95% of soot particles while allowing clean exhaust gases to pass through the porous walls.

【 High-Temperature Resistance】The diesel engine particulate filter is made from durable Cordierite or Silicon Carbide materials, which can maintain stable performance even under continuous high-temperature exhaust conditions.

【Support for Passive and Active Regeneration】Passive regeneration happens during regular driving. If the exhaust temperature is high enough, the soot is burned off automatically without any extra action. When the temperature is not high enough, active regeneration takes place by burning and removing the collected soot to add extra heat.

【Customizable Specifications】Our aftertreatment diesel particulate filter is available in round or square shapes, adjustable diameter, length, and cell density (100–350 CPSI) to suit different engine types and installation requirements.

【Compliance with Emission Standards】The DPF effectively reduces particulate emissions, helping vehicles meet Euro 4, Euro 5, and Euro 6 emission regulations.

As one of the diesel particulate filter manufacturers specializing in the catalyst industry for over three decades, our Sic/Cordierite DPF(diesel particulate filter) boasts high filtration efficiency and strong thermal durability, offering stable performance in diesel engine exhaust systems. It can efficiently reduce particulate emissions and help to compliance with stringent emission regulations, including Euro IV, V, and VI standards.

It is suitable for:

• Light-duty and heavy-duty commercial vehicles
• Buses and coaches
• Off-road machinery, such as construction and agricultural equipment
• Industrial diesel generators
• Retrofit emission control systems for older diesel engines

How it works

The most effective type is the so-called wall flow diesel particulate filter. Particulate matter is removed from the exhaust by physical filtration using a honeycomb structure similar to an emissions catalyst substrate but with the channels blocked at alternate ends. The exhaust gas is thus forced to flow through the walls between the channels, and the particulate matter is deposited as a soot cake on the walls. Such a universal DPF filter is made of ceramic honeycomb materials (cordierite, silicon carbide, or aluminium titanate).

Ceramic wall flow diesel particulate filter almost completely removes the carbon particulates over a wide range of engine operating conditions. Since the continuous flow of soot into the filter would eventually block it, it is necessary to ‘regenerate’ the filtration properties of the filter by burning off the collected particulate on a regular basis. Therefore, the exhaust temperature in Diesel passenger car applications is frequently increased until the collected soot is burned off. To reduce the burn-off temperature, the diesel particulate filter is typically coated with an oxidation function. This catalytic coating also contributes to the reduction of CO and HC through oxidation and in addition it can form NO2 to support the functionality of an SCR catalyst.
