Can CDPFs Be Customized? Which Shape is Better: Round, Square, or Oval?

Can CDPFs Be Customized? Which Shape is Better: Round, Square, or Oval?

Yes, CDPFs (Catalyzed Diesel Particulate Filters) support customization in terms of dimensions, shape, CPSI (cells per square inch), substrate material (cordierite or silicon carbide), and catalyst loading formulas. This allows CDPFs to be tailored to different vehicle types, installation conditions, and emission targets.

There are three main structural shapes commonly available: round, square, and oval. Choosing the best one depends on space constraints, exhaust layout, and system performance needs.

1. Round Structure

• Advantages: Widely compatible, uniform flow, easy to integrate

• Recommended for: Trucks, buses, small gensets

2. Square Structure

• Advantages: Maximizes cross-sectional area, suits flat space layouts

• Recommended for: Non-road machinery, industrial generator rooms, construction equipment

3. Oval Structure

• Advantages: Balances width and height; ideal for tight spaces with high flow demand

• Recommended for: Retrofitted vehicles, specialty equipment, compact exhaust modules

The best structure depends on your system’s exhaust layout, available installation space, pipe shape, and ease of regeneration and maintenance.

For OEM projects or special use cases, we recommend providing technical drawings or detailed measurements so that we can offer a precisely customized solution.
