I bought a "PUMA" 240V 3hp running 6hp rated. Puts out 12CFM at 90PSI. It works great for painting barely will operate a 90lb Harbor Freight sand blaster. You have to use the smallest tip. Also run the sand through a screen or small pieces will plug the nozzel. I have done my whole project frame, cab, etc using this. It's slow and cumberson. You need probably twice this CFM at 90PSI to have a good sand blast experience.
