Abstract:
1. A material processing system comprising: a processing chamber for processing a workpiece, the processing chamber having a processing chamber inlet and a processing chamber outlet; an exhaust chamber fluidly coupled to the processing chamber inlet, the exhaust chamber having an exhaust chamber inlet; a first exhaust line fluidly coupling the processing chamber outlet to the exhaust chamber inlet; a first air cleaner proximate to the exhaust chamber inlet; a first exhaust air mover in line with the first air cleaner, wherein the first exhaust air mover is a first blower configured to generate a first flow rate through the first exhaust line; a second exhaust line having a first end portion and a second end portion, each of the first and second end portions being fluidly coupled to the exhaust chamber upstream from the processing chamber inlet; a second air cleaner in the second exhaust line; and a second exhaust air mover in the second exhaust line in line with the second air cleaner, wherein the second exhaust air mover is a second blower configured to generate a second flow rate through the second exhaust line, and wherein the second flow rate is different than the first flow rate, wherein, during processing of the workpiece, the processing chamber, the exhaust chamber, the first exhaust line, and the second exhaust line are configured to form a closed loop system.
