The air operated PSM-500 uses a hollow drill. The unit feeds water through the drill to the cutting head, flushing out deposits as they are loosened. Hollow shafts are used with brushes or buffing tools for lighter deposits. Typical applications include: Paint Heat Exchangers, Oil Coolers on Plastic Molding Machines, Oil Coolers on Compressors and Hydraulic Oli Coolers on Engines.
