The OTC Portable Diesel Particulate Filter (DPF) Cleaner can be placed as close to the vehicle as possible and stored wherever needed, due to its portability. This system can clean DPFs from 6” to 15.5” in diameter using shop or compressed air of at least 100 psi and 20 cfm sustained airflow. Once started, the cleaning process can be completed with minimal operator oversight. The Focused Air Jet Technology concentrates a precise high-pressure stream of air directly into every cell. The design of the DPF Cleaner provides maximum durability and contains no internal filters for limited user maintenance.
