Abstract:  
Part Three We are presenting this informative article as a series. In this issue, we will cover Pressure Blast Machines, Nozzles, and Operator Safety. PRESSURE BLAST MACHINES A blast machine is primarily a storage device to hold abrasive for release into an air stream. Although it appears to be a little more than a steel tank, there are a number of integral parts that make sizeable differences in safety, convenience, and efficiency. Poorly designed blast machines are one of the biggest culprits responsible for lost air flow and pressure. Basic engineering logic reveals that the greatest air flow efficiency takes place when restrictions are eliminated and friction losses are kept to a minimum.
