The OTC DPF Cleaner is an OEM-tested, dealer-approved DPF cleaning system designed to clean the diesel particulate filter element now being used on diesel engines. The patented cleaning process allows the DPF to be cleaned as part of a general maintenance schedule at the service location with minimal time away from the vehicle. The unit consists of enclosed HEPA-filtered cabinet, a provision for 120-psi to 150-psi air pressure and a strong vacuum which helps control loose ash in the cabinet.
