DPF filter problems in your machine? Leave it to us

We regenerate and clean DPF filters in our service center using modern equipment designed for machines operating in the harshest conditions. Customers can send the filter directly to us, where we will perform diagnostics, a full cleaning, and a flow test to restore the filter to full capacity. If on-site removal is not possible, our mobile service will come to you – we perform diagnostics, remove the filter, take it for regeneration, and then return and reinstall it, ensuring your machine is fully operational. Entrust your filter to specialists with years of experience who will ensure your machine returns to work quickly and help you avoid costly downtime.

Comparison of a clean and clogged DPF filter core

Natural wear, real consequences

Why does the particulate filter get clogged?

Over time, a DPF filter undergoes natural clogging as contaminants from engine operation accumulate inside. Two types of deposits build up: soot, which can be burned off during operation, and ash, which does not burn and gradually fills the filter structure. This ash is the primary cause of permanent DPF clogging and the gradual loss of its permeability.

During operation, ash settles in the channels of the ceramic insert, reducing the exhaust flow area. In extreme cases, it forms a dense, hard layer blocking the central part of the monolith, thereby restricting flow through neighboring channels as well. This type of contamination cannot be burned off or removed with chemical additives – the only effective method is specialist filter regeneration outside the vehicle.

What are the typical

Symptoms of a clogged DPF/FAP filter?

A clogged particulate filter sends clear signals that excessive backpressure is building up in the exhaust system. Most often, the driver or operator notices a drop in power, problems with smooth driving, or the vehicle entering limp mode. A DPF warning light also appears on the dashboard, indicating an excessive amount of soot in the filter.

Noticeable power drop, worse throttle response
Rising engine oil level
Increased fuel consumption, especially under load
Smell of unburnt fuel
Machine entering limp mode, limited RPM
Increased engine idle speed

What is a DPF filter?

Why is DPF condition crucial for your machine's operation?

A DPF (Diesel Particulate Filter) is an exhaust system component used in diesel engines, including construction machinery, heavy vehicles, and vans. Its task is to trap harmful soot and ash particles produced during diesel combustion, allowing the engine to meet emission standards and ensuring proper engine operation.

The filter usually consists of a steel body and a ceramic monolith with a dense network of channels, arranged alternately and partially closed. This forces exhaust gases to pass through the porous walls of the channels, where soot particles and other contaminants are trapped.

Cleaning and regeneration process

Diagnostics and filter preparation

Initially, the filter is mounted in a diagnostic device that allows us to precisely check:

Backpressure

Air flow speed

Filter clogging level

After establishing initial parameters, a special professional cleaning agent is introduced into the filter. The detergent dissolves hard deposits, soot, and ash, while protecting the ceramic insert from damage – which is critical for filters used in construction machinery working under heavy conditions.

 

Trust the professionals

Hydrodynamic cleaning with control at every stage

The main part of the regeneration is hydrodynamic washing, which takes place in several precise phases:

Washing in the direction opposite to exhaust flow
The filter is subjected to sequences of filling with water and detergent, compressed air blasts, and controlled flow cycles. The process takes place at a temperature of approx. 70°C to effectively remove contaminants without overloading the insert.

Individual machine settings
Cleaning parameters are selected for the specific filter design – the monolith in loaders and excavators differs from those in road machines. By adjusting pressure, impact force, and cycle time, we ensure maximum effectiveness and safety.

Contamination analysis during the process
At every stage, we monitor what flows out of the filter. This allows us to precisely determine the degree of contamination and assess whether the washing process needs to be extended.

Final washing in the working direction
The final phase involves cleaning again in the direction opposite to exhaust flow, which removes any remaining ash and soot residues.

Drying and quality control

After washing, the filter undergoes a drying process:

  • first, water residues are removed under high air flow
  • then the filter is heated at a temperature above 120°C
  • after drying, cooling follows to stabilize the ceramic structure

Finally, we perform another measurement of backpressure and flow to confirm the effectiveness of the regeneration.

We are where you need us

Construction Machinery Service - Professional diagnostics and repair

For over 20 years, we have continuously specialized in construction machinery service, providing fast and effective repairs in the field and in our workshop. Thanks to many years of experience and excellent knowledge of hydraulic, drive, and electronic systems, we are able to precisely diagnose any fault and restore the machine to full efficiency in the shortest possible time. Our mobile service is ready for immediate intervention – we travel directly to the machine's workplace, perform diagnostics, and undertake necessary repairs. In the case of more serious faults, we efficiently dismantle components and take them to our service center.

Call us and schedule a service for your machine – we will help you get back to work as quickly as possible.

 

Prevention that protects equipment and budget

Why is it worth regularly servicing the DPF filter in construction machinery?

Systematic control and DPF filter service is the best way to avoid costly repairs and unplanned machine downtime. Contaminants accumulate in the filter gradually, so the earlier we detect the beginnings of clogging, the faster and cheaper full capacity can be restored. What is a minor backpressure increase today could lead to a serious exhaust system failure, turbocharger damage, or even stop the machine during operation tomorrow.

Still wondering?

Check out why you should choose us

  • Every repair quote is comprehensive and clear – you know what you're paying for.
  • We service DPFs from anywhere in Poland, ensuring efficient express completion.
  • Through processes, procedures, and standards, we minimize machine downtime.

 

 

What machines do you operate?

We regenerate DPF filters used in construction machinery such as excavators, loaders, dumpers, bulldozers, and road construction machines. We also service trucks and special vehicles used on construction sites. The cleaning parameters are selected individually according to the design of each filter

How long does DPF filter regeneration take?

The standard process takes approximately 24 hours from the moment the filter is delivered. The time may be extended if the filter is exceptionally heavily clogged or requires additional cleaning cycles. The final turnaround time is always determined after diagnostics.

Does regeneration affect fuel consumption?

Yes - after restoring proper exhaust flow, the engine runs more smoothly and efficiently. In most cases, fuel consumption noticeably decreases, and the machine regains full power. This is one of the key benefits of regular DPF maintenance.

How much does DPF filter cleaning cost?

The price depends on the condition of the filter and the degree of its clogging. To receive a preliminary estimate, simply contact us. The exact cost is provided after the filter is delivered and diagnostics are performed to determine the required scope of work.

How can I deliver a clogged filter?

You can deliver the filter to us in several convenient ways. The easiest method is to send it by courier - you can do this yourself or ask us to arrange the pickup. We also offer a mobile service that can come to your location, remove the filter from the machine, take it to our workshop for regeneration, and return it after the service, reinstalling it to ensure everything works correctly. This way, you can choose the method that is most convenient for you.
