Abstract

A tool for removing particulate matter from a diesel particulate filter (DPF) includes a container defining a chamber that has an open end, and a support associated with the open end that supports a first axial end of the DPF and forms a seal around an outside surface of the can of the DPF and the container. An air nozzle mounted proximate to a second axial end of the DPF directs a narrow flow of air through the DPF that passes through a portion of the DPF element bundle and exits through the first axial end into the container.
