Solutions & Benefits

DPF Cleaning

ENSURING OPTIMAL PERFORMANCE WITH 

our 8-Step DPF Cleaning Process

DPF Cleaning - Initial Inspection

STEP 1

Initial
Inspection

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

DPF Cleaning - Drying

STEP 5

Eliminate Moisture & Dry

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

DPF Cleaning - Documentation

STEP 2

Record & Document

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

DPF Cleaning - Thermal Regeneration

STEP 6

Thermal
Regeneration

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

DPF Cleaning - Blast Cleaning

STEP 3

Blast
Cleaning

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

DPF Cleaning - Cooling and Final Check

STEP 7

Cooling & 
Final Check

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

DPF Cleaning - Aqueous Cleaning

STEP 4

Aqueous
Cleaning

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

DPF Cleaning - Packaging

STEP 8

Package & Transport

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