Benefits the customer can expect with Durafit DPFs

As demands for cleaner emissions increase, the designers of diesel aftertreatment systems continue to focus on ways to improve the performance of those systems to remove more particulate matter, and improve the overall efficiency of the filtration installed on the vehicle.

Improvements targeted included enhancement of the coating on the substrate to improve chemical reactions to “clean” more effectively.

Another way performance can improve is in the design of the substrate to capture more soot and ash during normal operation.

Some applications have shifted to a design that features larger inlet cells, and smaller outlet cells, to provide greater soot collection, which in turn will allow the unit to operate longer between regenerations and cleaning.

Severe-duty low RPM, frequent stop-and-go applications are where this makes sense. These enhanced design units provided superior soot and ash collection, more consistent back pressure, and improved efficiency in filtration. 

The traditional DPF is manufactured utilizing a symmetrical cell design substrate. The enhanced Asymmetrical design offers a far greater capacity for ash and soot loading, better pressure drop performance, keeping the unit running longer between regenerations or cleaning.

Durafit relies heavily on the OEM design, to match the operating capability of the unit when installed on a vehicle.  Meaning utilizing an Asymmetrical substrate when the original application uses it. In many cases, aftermarket manufacturers are using a Symmetrical substrate in these applications, as a cost-cutting measure. These units can be expected to have a shorter life span on the vehicle, will need to be regenerated, cleaned and removed more frequently than a unit that uses an Asymmetrical substrate.

Your vehicle operates best when you use Durafit replacement DPFs that are designed to work like the OEM part.

Tried. Tested. Proven. Durafit is building DPFs above standards.
