Abstract

According to an exemplary embodiment of the present disclosure, a system for removing matter from a filtering device of a work machine includes a gas pressurization assembly. An element of the gas pressurization assembly is removably attachable to a first orifice of the filtering device without removing the filtering device from a work machine to which the filtering device is connected. The system also includes a heat source fluidly connected to the gas pressurization assembly.
