MANNOL DPF Foam Cleaner is a professional tool designed for cleaning and restoring the efficiency of diesel particulate filters (DPF) without the need for dismantling. It is suitable for all diesel engines, whether naturally aspirated or turbocharged, equipped with these filters. It is also applicable for diesel engines that have automatic regeneration systems for diesel particulate filters, as well as those that do not. Properties include initiating the regeneration process of the particulate filter, promoting complete soot burning, and acting as a combustion catalyst. It is particularly effective for vehicles used in urban conditions and during the cold season. The cleaner restores the full capacity of the particulate filter and the original engine power by reducing the filter's hydrodynamic resistance, leading to fuel savings. Its neutral low-ash formula ensures it evaporates without a trace and is removed from the filter. Regular use extends the service life of the particulate filter and reduces operating costs, potentially eliminating the need for DPF replacement. It also reduces the toxicity of exhaust gases. To use, remove one of the particulate filter sensors (pressure or temperature) and insert the spray gun into the orifice. Start the engine and clean at idle. Spray the contents of the can towards the particulate filter periodically for 10 seconds, with 3-5 second intervals, until the can is empty. Stop the engine and reinstall the sensor. Check the cleaning efficiency with a tester on the stand or during a test drive. After regeneration, ensure the on-board computer does not display an error code; manual error deletion may be required in some cases. For ongoing maintenance, use 9994 Mannol filter cleaner between service periods.
