I was referring more to the compressor cfm. If your doing smaller parts, a bench type blaster will work fine. Using glass bead 50 to 60 psi works good. If you go with the higher pressure it comes off good but leaves the surface too textured for anodizing without etching and can embed media into the substrate. Anodize doesn't chip or peel like other coatings.
