What size air compressor do I need for my sandblaster?

The size of the air compressor designates the maximum size of the blast nozzle usable at a generally required operating pressure of approximately 100 lbs. This, in turn, suggests the size of the machine for consideration – bearing in mind the practical machine size is one which will provide ½ -1 hour continuous operation without refilling of the pot.
