The LS PBX has capacity for (4) 20lb cylinders per cycle. The (2) 20 HP motors turn the LS TurboShot™ blast wheels. The bi-directional design throws a high volume of shot to quickly clean the full surface of the cylinders. The cylinders are held in place with heavy-duty manganese fixture rods that are spring loaded for fast loading and unloading. The machine is easy to maintain overtime with replaceable cabinet liners in the blast area. For higher volumes or even less maintenance time you can upgrade to a manganese cabinet with replaceable manganese wear liners.
