Abstract

A particulate filter inspection system for a particulate filter includes a compressed air source, a primary conduit, a controller, a probe, and a gauge. The compressed air source is configured to draw air from an air source. The primary conduit is configured to receive the air from the compressed air source. The probe is coupled to the primary conduit and communicable with the controller. The probe is configured to interface with a face of the particulate filter to provide the air to only a sector of the particulate filter. The gauge is configured to determine a pressure of the air within the primary conduit when the probe is providing air to only a sector of the face of the particulate filter. The controller is configured to receive the pressure from the gauge, compare the pressure to a target upper pressure, and provide an indication that the particulate filter is dirty if the pressure is not lower than the target upper pressure.
