Abstract
Embodiments of recirculating filtration and exhaust systems for material processing systems are disclosed herein. A material processing system configured in accordance with one embodiment includes an enclosure for processing a workpiece, the enclosure having an enclosure inlet and an enclosure outlet. The system also includes a first flow path fluidly coupled to the enclosure inlet and the enclosure outlet, and a first filtration assembly in the first flow path. The first filtration assembly draws airflow from the enclosure and returns the airflow to the enclosure. The system further includes a second flow path in fluid communication with the first flow path upstream from the enclosure inlet, and a second filtration assembly in the second flow path. The second filtration assembly draws airflow from the first flow path and returns airflow to the first flow path.
