Sandblasting Nozzles Vs Air Requirements
Before you chose a nozzle, you need to know a little bit more about your air compressor. If we had a pound for everytime someone told us that they had a 'big' air compressor, we'd retire early.
Unfortunately, the physical size of the compressor may not bear any realtionship to the size of nozzle it can 'drive'. We mean the hole or bore size of course...
There is a quick rule-of-thumb, you can use as a guide to determine your CFM (Free AIr Delivery Cubic Feet Per Minute)
For a piston compressor multiply the horse power by 3 and by 4 for a vane compressor..

Obvious things first - what kind of sandblasting are you using the nozzle for? If it's for lettering, then use a larger bore nozzle as possible, bearing in mind you still need to be blasting at a reasonable pressure. For design work, a smaller bore nozzle may be better, however, for Photostencils, you can benefit again from a wider bore size to get a wider spread of fine grit - Minefield isn't it...
The chart gives you an idea of nozzle Bore Size Vs CFM Vs PSI (blasting pressure) A single phase compressor for example can rarely achieve over 25CFM, unless it's got a dual motor...3 Phase compressor generally give you a significantly higher CFM.
