Function: This DPF is designed to efficiently capture and remove particulate matter (PM) or soot from diesel engine exhaust gases, helping your vehicle meet stringent emission regulations and operate more cleanly.

Working Principle: The filter traps soot particles as exhaust gases pass through its porous ceramic structure. With a catalytic coating applied, the DPF not only captures PM but also promotes oxidation of carbon (C) into CO₂ and enhances passive regeneration under lower exhaust temperatures.

Chemical Reaction:
C (soot) + O₂ → CO₂
NO₂ + C → CO + NO

Features:

• High Filtration Efficiency – Captures over 95% of diesel soot and PM

• High Thermal Resistance – Operates up to 1400°C without damage

• Long Service Life – Superior durability compared to cordierite filters

• Low Back Pressure – Improves engine performance and fuel economy

• Universal Fit – Suitable for a wide range of diesel vehicles

• Custom Orders Supported – We accept drawings and special requirements

Purchasing notice:

2.Please replace the catalyst of the original size and do not modify it

3.Due to increased emissions standards, these items are not certified for sale in California, New York, Maine and Colorado.

4.Allow us to have an error of ±2mm,It will not affect normal us.

Working Principle

Diesel Particulate Filters (DPFs) are designed to trap and remove particulate matter (PM) and soot from diesel exhaust gases. The filter’s wall-flow structure forces the gas through porous walls, while particles are captured inside the channels.

During regeneration, the captured soot is burned off at high temperatures via oxidation reactions:(

C (soot) + O₂ → CO₂

This process reduces emissions, protects the turbocharger and EGR systems, and ensures compliance with environmental regulations.

❓ Frequently Asked Questions (FAQ)

Q1: Is this DPF compatible with my vehicle?

A: This is a universal DPF core, designed for many diesel vehicles. To ensure fitment, please send us your car model, engine type, year, or a photo of your current filter. We will help confirm before purchase.

Q2: What is the difference between Silicon Carbide and Cordierite DPFs?

A: Silicon Carbide (SiC) offers higher thermal resistance (up to 1400°C), longer life, and better filtration than cordierite. It is ideal for heavy-duty or high-temperature applications.

Q3: Will this DPF help my vehicle pass emissions testing?

A: Yes. A clean and properly installed DPF helps reduce PM (Particulate Matter) emissions and supports compliance with most diesel inspection standards. Be sure your engine is in good condition and regeneration is working.

Q4: Can the DPF be cleaned or reused?

A: Yes. DPFs can be cleaned by professional thermal or liquid regeneration methods. However, if the filter is physically damaged or melted, replacement is recommended.

Q5: Does this DPF support regeneration?

A: Yes. Silicon Carbide DPFs support both passive and active regeneration, depending on your vehicle’s engine system. Passive regeneration occurs during high-speed driving; active regeneration is triggered by the ECU when needed.(Yes, only for coated DPF)

Q6: Will this DPF cause back pressure or performance issues?

A: No. Our filters are designed with optimized cell density and wall thickness to maintain proper flow rate and engine performance. A new DPF may improve fuel economy and turbo response if your old one was blocked.

Q7: Can I install this DPF myself?

A: We recommend professional installation. The filter core may need to be welded into an existing housing or adapted to your exhaust pipe.

Q8: Do you provide custom sizes or private label?

A: Yes. We offer OEM/ODM services and can produce DPFs according to your drawings, dimensions, or special coating needs. Contact us for details.
