Phil-
Beware of the ratings found on most compressors today... They are
wildly overrated, and vary a great deal from manufacturer to manufacturer.
As a general rule, always buy more compressor than you think you'll ever
need.. ( well, within limits of course) A basic beadblast cabinet will need
around 3-5 horsepower, which of course rules out 115vac powerlines. You
can reduce the diameter of the blast nozzle to conserve air, but of course
productivity is greatly reduced. The "s" stands for standard, i.e..
controlled temperature + pressure. I doubt it gives the compressor rating
any more believability, though. Don't buy an "oilless diaphragm
compressor", as they are extremely loud and ill suited for continuous duty.
A two stage 3-5 Hp vertical tank compressor (Ingersol, I think) from Home
Depot is around 8-900 bucks ISTR. (FI-
I own Home Depot, at least I should based on my expenditures..) A good bit
'o change, but the last compressor you'll need.
The link below is an excellent treatise on what you'll need.

Subject: Beadblast Setup
I would like to ask the 'List' what are the minumim air compressor
outputs to operate a small benchtop (sand/bead) blast cabinet. Most
cabinets state 5 cfm @ 100 psi, but most compressors are rated around
5.5 cfm @ 90 psi. Also, some makers of compressors are using SCFM. What
does the 'S' stand for? I am looking at compressors with 8 gal tanks to
ones with from 20 - 60 gal tanks. Enlighten me. Thanks
