Professional DPF/FAP Filter Cleaning Machine – DPF-S900

Professional DPF and FAP Filter Cleaning Machine

The DPF-S900 is a professional machine designed for cleaning removed DPF/FAP diesel particulate filters from passenger cars and light commercial vehicles.

The system combines the essential stages of professional DPF cleaning in one machine: testing, washing, rinsing, drying and before/after performance verification.

It is an ideal solution for automotive workshops, diesel specialists and professional DPF cleaning centers looking to provide a controlled and repeatable particulate filter cleaning service.

Professional Diesel Particulate Filter Cleaning

During diesel engine operation, the DPF captures particulate matter produced during combustion.

Over time, the internal structure of the filter can accumulate:

• soot;

• ash;

• combustion residues;

• contaminants that restrict exhaust gas flow.

Excessive accumulation can increase DPF backpressure, cause frequent regeneration cycles, reduce engine performance and trigger the DPF or Check Engine warning light.

Professional cleaning is designed to remove accumulated contamination and restore the exhaust gas flow through the filter as effectively as possible.

DPF Backpressure Testing Before and After Cleaning

One of the key advantages of the DPF-S900 is the ability to perform backpressure testing before and after the cleaning process.

This allows the operator to compare filter performance and evaluate the result of the cleaning operation.

For professional workshops, before/after testing provides an objective method of verifying the cleaning result rather than relying only on the washing process itself.

Automatic DPF Washing and Controlled Cleaning Process

The DPF-S900 performs an automatic cleaning cycle controlled through a PLC system and touchscreen interface.

The particulate filter is secured using the appropriate adapters, and the cleaning cycle can be configured according to the type, size and level of contamination of the filter.

The system provides:

• controlled DPF washing;

• circulation of cleaning fluid through the filter structure;

• removal of loosened soot, ash and residues;

• filter rinsing;

• integrated drying;

• final performance verification.

Integrated DPF Drying System

After washing and rinsing, the particulate filter must be properly dried before being reinstalled on the vehicle.

The DPF-S900 features an integrated drying system, allowing the complete cleaning process to be performed using one professional workstation.

This reduces the need for additional equipment and improves workflow efficiency inside the workshop.

Filtration and Recirculation System

The machine incorporates a filtration circuit designed to separate contaminants removed from the DPF during the cleaning process.

Continuous filtration helps protect the pump and internal hydraulic circuit while supporting a controlled and repeatable cleaning procedure.

PLC Control and 7-Inch Touchscreen

The DPF-S900 is equipped with a PLC control system and 7-inch touchscreen, allowing the operator to monitor and control the cleaning cycle.

Automatic programs simplify daily operation and help ensure consistent cleaning procedures in professional automotive workshops.

Applications

The DPF-S900 is suitable for cleaning particulate filters used on:

• diesel passenger cars;

• SUVs;

• vans;

• light commercial vehicles;

• other compatible DPF/FAP filter configurations.

The machine can be used with particulate filters found in modern emission-control systems, including applications associated with Euro 4, Euro 5 and Euro 6 vehicles, depending on the construction and dimensions of the filter.

DPF, FAP and Diesel Emission-Control Systems

The DPF/FAP is an important component of a diesel vehicle's emission-control system and may operate together with other components such as:

• DOC diesel oxidation catalyst;

• catalytic converters;

• SCR systems;

• AdBlue systems;

• exhaust pressure sensors;

• exhaust temperature sensors.

Professional DPF cleaning should always be combined with proper diagnosis of the vehicle's emission-control system.

Cleaning the particulate filter without identifying the original cause of excessive blockage may result in the filter becoming restricted again.

When Is Professional DPF Cleaning Recommended?

A professional DPF cleaning process may be appropriate when symptoms include:

• DPF warning light;

• Check Engine warning light;

• frequent DPF regeneration;

• excessive exhaust backpressure;

• reduced engine power;

• increased fuel consumption;

• engine limp mode;

• unsuccessful or incomplete regeneration cycles.

When Should a DPF Be Replaced Instead of Cleaned?

A professional cleaning machine cannot repair a physically damaged particulate filter.

Replacement or specialist inspection may be required when the filter has:

• a cracked ceramic substrate;

• a melted internal structure;

• detached internal elements;

• severe housing deformation;

• heavy oil or coolant contamination;

• irreversible mechanical damage.
