BLASTING TECHNICAL INFORMATION MC Finishing

measured by pounds per square inch (psi), industrial blasting is effectively done between 20 and 90 PSI. The higher the PSI the higher the air speed. The volume delivered of the air/media mix is determined by the orifice or opening diameter of the nozzle with pressure blast systems or air jet diameter of the suction blast gun body.
