Professional DPF/FAP and Catalyst Cleaning Machine – DPF1800 Front Door

Professional DPF/FAP and Exhaust Aftertreatment Cleaning Machine

The DPF1800 Front Door is a high-capacity professional machine designed for cleaning DPF/FAP diesel particulate filters and compatible components from exhaust aftertreatment systems.

It is intended for automotive workshops, professional DPF cleaning centers, diesel specialists and service companies working with passenger cars, vans and commercial vehicles.

The DPF1800 platform combines the main stages of the professional cleaning process in one machine: testing, washing, rinsing, drying and before/after performance verification.

Professional Diesel Particulate Filter Cleaning

Diesel particulate filters are designed to capture solid particles produced during engine combustion.

Over time, the internal structure of a DPF can accumulate:

• soot;

• ash;

• carbon deposits;

• combustion residues;

• oil-related contaminants;

• deposits that restrict exhaust gas flow.

When the filter becomes heavily restricted, exhaust backpressure may increase and the vehicle may experience frequent regeneration cycles, reduced engine performance, higher fuel consumption or limp mode.

The DPF1800 Front Door allows the removed filter to be cleaned using a controlled professional process and the result to be checked after treatment.

DPF Backpressure Testing Before and After Cleaning

Professional DPF cleaning should involve more than simply washing the filter.

The DPF1800 Front Door allows backpressure testing before and after cleaning, enabling the operator to compare filter performance and evaluate the effectiveness of the cleaning process.

Before/after testing provides workshops with an objective method of verifying the result and documenting the service performed.

Automatic and Controlled DPF Washing

The machine uses automatic washing programs controlled through a PLC system and touchscreen interface.

The particulate filter is positioned inside the cleaning chamber using the appropriate adapter, while the system circulates water and cleaning solution through the internal filter structure.

The cleaning process is designed to remove accumulated soot, ash and other deposits while restoring exhaust gas flow through the filter.

Integrated Drying System

After washing and rinsing, the DPF must be properly dried before final testing and reinstallation on the vehicle.

The DPF1800 Front Door features an integrated drying system, allowing the main cleaning stages to be completed in the same professional workstation.

This improves workshop efficiency and reduces the need for separate drying equipment.

Advanced Filtration and Water Recirculation

During the cleaning cycle, contaminants removed from the particulate filter are carried into the machine's filtration circuit.

The DPF1800 Front Door uses an advanced filtration system designed to separate residues from the cleaning fluid.

The system includes:

• stainless-steel mesh filtration;

• dual stainless-steel filtration;

• 30-inch precision filtration;

• multiple filter cartridges.

The recirculation system helps reduce unnecessary water and detergent consumption while supporting a controlled cleaning process.

Pneumatic Front Door System

The Front Door version features a pneumatic front access system designed to simplify loading and positioning of particulate filters inside the cleaning chamber.

Its large working area makes the machine suitable for a wide variety of filter sizes used on passenger cars and commercial vehicles.

PLC Control and 10-Inch Touchscreen

The main machine functions are managed through a professional PLC control system.

A 10-inch HMI touchscreen allows the operator to select cleaning programs and monitor the cleaning cycle.

Automatic programs help standardize the process and simplify daily operation in professional workshops and DPF cleaning centers.

DPF Cleaning for Cars, Vans and Commercial Vehicles

The DPF1800 Front Door is suitable for workshops dealing with a wide range of applications, including:

• diesel passenger cars;

• SUVs;

• vans;

• light commercial vehicles;

• commercial vehicles;

• trucks;

• large DPF filter assemblies.

With a maximum loading capacity of 250 kg and a cleaning chamber measuring 1800 × 600 × 1000 mm, the machine can process significantly larger filter assemblies than compact DPF cleaning systems.

DPF, FAP, Catalysts and Exhaust Aftertreatment Systems

Modern diesel emission-control systems can include several components, such as:

• DPF – Diesel Particulate Filter;

• FAP – Filtre à Particules;

• DOC – Diesel Oxidation Catalyst;

• catalytic converters;

• SCR – Selective Catalytic Reduction systems;

• AdBlue systems;

• exhaust pressure sensors;

• exhaust temperature sensors.

Depending on component design, dimensions and compatibility, the DPF1800 platform can be used for cleaning suitable filters and exhaust aftertreatment components.

Euro 4, Euro 5 and Euro 6 Emission-Control Systems

The DPF1800 Front Door is designed for professional use with compatible particulate filters and aftertreatment components found on vehicles equipped with Euro 4, Euro 5 and Euro 6 emission-control systems.

The exact exhaust configuration varies according to vehicle manufacturer, engine type and emission standard, so each component should be inspected and identified before cleaning.

When Is Professional DPF Cleaning Recommended?

Professional cleaning may be required when symptoms include:

• DPF warning light;

• frequent regeneration cycles;

• unsuccessful DPF regeneration;

• excessive exhaust backpressure;

• reduced engine power;

• increased fuel consumption;

• engine limp mode;

• excessive ash accumulation;

• restricted exhaust gas flow.

The cause of excessive DPF blockage should always be diagnosed before or together with the cleaning operation.

When Should the Filter Be Replaced Instead of Cleaned?

Professional washing cannot repair a particulate filter that is physically damaged.

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

• a cracked ceramic substrate;

• melted internal channels;

• detached internal elements;

• severe housing deformation;

• heavy oil or coolant contamination;

• irreversible mechanical damage.
