Our 8-Step DPF Filter Cleaning Process

Smart Solutions for Smarter Fleet Operations

Our Cummins-approved 8-step cleaning process is designed to restore Diesel Particulate Filters (DPFs) and Diesel Oxidation Catalysts (DOCs) to peak performance. Each step ensures your filters are thoroughly inspected, cleaned, and tested for maximum efficiency, emissions compliance, and long-term reliability across your fleet.

Initial Inspection

01

We thoroughly inspect each filter for signs of external damage, contamination, and wear, identifying any issues that might affect performance.

Record & Document

02

We record initial airflow, weight, and condition to create a baseline, ensuring clear tracking of improvements throughout the cleaning process.

Blast Cleaning

03

Using high-pressure compressed air, we carefully dislodge large soot and ash particles from the filter, preparing it for deeper cleaning.

Aqueous Cleaning

04

The filter undergoes a high-pressure water cleaning, reaching deep into the filter substrate to remove smaller particles that air-blasting alone may miss.

Eliminate Moisture

05

The filter is dried to eliminate any residual moisture, preventing interference with the thermal regeneration phase.

Thermal Regeneration

06

The filter is heat-treated at controlled temperatures to burn off remaining fine particulates, ensuring thorough decontamination.

DPF Cleaning Process - Cooling and Final Check

Cooling & Final Check

07

After cooling, we perform a final airflow test and structural check to confirm that the filter meets performance standards.

Package & Transport

08

The cleaned filter is securely sealed and labeled for safe transport, along with detailed documentation of the cleaning results.
