The DYNAMAX DPF Cleaning Gun is a robust, professional-grade tool engineered to perform deep-cleaning of diesel particulate filters (DPFs) without requiring costly removal or replacement. Built around a pressurised tank and precision trigger mechanism, this system is designed to be used in conjunction with the matching DYNAMAX Air Jet Fluid cleaning liquid for optimal results.
Why this solution matters
Modern diesel vehicles increasingly rely on DPF systems to comply with emissions standards. Over time, filters become clogged with soot and ash, reducing performance, increasing fuel consumption and potentially triggering fault codes. The DYNAMAX DPF Air Jet Gun enables workshops and technicians to restore filter functionality in situ, reducing downtime, avoiding the cost of replacing the entire filter and delaying the need for forced regeneration or full unit removal.
Key Features & Benefits
- Compression‐tank air-jet system: The device features an integrated compression tank that delivers cleaning fluid under pressure directly into the DPF via the pressure or temperature sensor opening.
- Tailored for DYNAMAX Air Jet Fluid: The tool is specifically designed for use with DYNAMAX’s cleaning solution, making the chemical/mechanical combination highly effective at dissolving soot and contaminant build-up.
- Minimal disassembly required: Instead of removing the entire DPF housing, the gun allows you to clean through the sensor or probe hole. According to the technical data sheet, the engine should be off, the exhaust at ambient temperature and leak-free.
- Controlled cleaning process: The fluid is applied in 5-second intervals and the system recommends at least 500 ml of cleaning mixture depending on contamination levels. After treatment, sensors are reinstalled and a test drive is carried out so that dissolved soot can be burnt off by the vehicle’s regeneration process.
- Cost-effective maintenance: By restoring flow and regeneration capability rather than replacing the unit, workshops can offer an economical service – especially valuable for fleet vehicles and high-mileage diesels.
Application & Workshop Procedure
- Ensure the engine is off, exhaust system is cooled and leak-free, and all sensors and EGR components are functioning correctly (per manufacturer guidance).
- Remove the temperature/pressure sensor from the DPF housing.
- Fill the gun’s tank with the specified cleaning fluid mixture and connect to a compressed-air supply (typically 2.5 – 4.0 bar as per fluid instructions).
- Spray the DPF for a minimum of 500 ml of fluid in short intervals. For heavier contamination a higher dose may be required.
- Reassemble sensors, start the engine, and conduct a test run of ~20 minutes to allow the dissolved soot to burn off via normal regeneration.
- Confirm DPF performance improvement (via back-pressure test, regeneration behaviour or onboard diagnostics).
Summary
For workshops specialising in diesel maintenance and regeneration services, the DYNAMAX DPF Cleaning Gun represents a smart investment in productivity, cost-control and customer satisfaction. By combining high-pressure application with a chemically engineered cleaning fluid, the system provides a professional, efficient solution for one of the most common and costly challenges in modern diesel repair. With correct application the tool helps extend DPF life, reduce unnecessary replacement and restore vehicle performance—and that’s a compelling service offering in any garage.
Note: Always refer to the official product manual (inside of box), and observe vehicle manufacturer instructions and local emissions-related regulations when performing DPF maintenance.
