This class of blasters has come way down in price over the last few decades. I've used pro-grade pressure pots with 175 cfm gas compressors....this home hobbyist rig will take a lot longer than a pro rig, but it WILL get the job done. You should have at least 15 CFM air with this rig (3hp motor or more). You can run with smaller compressors but the workspeed will be tediously slow. This blaster comes with 2mm, 2.5mm, 3mm and 3.5 mm ceramic nozzles. The 3.5 is mounted on the deadman gun right out of the box. Use FINE grits (or extra fine) with the 3.5 or you will spend more time unclogging the nozzle than actually blasting. The grit you use must be bone dry-clumpy grit is a no no. I use fine grit crushed glass from Northern Tool. The two smallest nozzles...wow, you'd need super fine grit to work with the smaller nozzles without clogging.
