During normal operation, employing a 0.060" diameter nozzle, a 0.025" diameter tank
orifice, and 25 micron aluminum oxide powder; a full tank of powder, approximately 10
lbs. (standard tank), will last about 6 - 9 hours of actual blast time; air will be used at
about 250 standard cubic feet per hour (SCFH) at 80 psig; and nozzle life will be 8 to 35
hours depending on the amount of wear that can be tolerated.
