The present disclosure provides a method and apparatus for measuring ash deposit levels in a particulate filter comprising at least one cell. One or more indicator components is inserted into the at least one cell so as to lie upon any deposits contained therein. Radiation is emitted from a radiation source into the cell, and the position of the one or more indicator components is detected on the basis of the emitted radiation. The deposit level within the cell is then calculated on the basis of the position of the one or more indicator components.

Method and apparatus for measuring ash deposit levels in a particulate filter

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.

Filter cleaning tool and method

A system for removing matter from a filtering device is disclosed. The system may have an impact wave generating device. The system may further have a vacuum source to draw matter away from the filtering device.

Filter purge system utilizing impact wave generating device and vacuum source

A particulate removal tool and method are provided to remove the particulates such as ash and soot from a particulate filter. The particulate filter can be placed on a filter holder in a housing of the tool where a quick burst of air can be provided to clean the particulate filter. The air then can travel to a container which includes additional filter to filter the air. A vacuum can be used to remove additional particulates from the container.
