<p><span style="color: #ffffff;">It is easy to change out abrasive. If you have one hopper, simply pressurize the unit and collect all the abrasive and save it for use later. Then load the different grade abrasive into the hopper. If you have 2 hoppers, we just "T" into the abrasive feed line prior to going to the cutting head and switch from one to the other in seconds.</span></p>
