sandblasting setup

[glassydame52]

I realize this is an older post, I am curious as to your sandblasting set up.  I am somewht confused over the siphon vs pressure pot systems.  I have a compressor, 7CFM with 90psi. 4 HP and 11 gallon tank.  Most cabinet set ups want 11-14 CFM, then I found an article about using a smaller

nozzle to compensate for lower CFM.  I  have looked at tptools and northern tool, harbor freight and Grainger and texas blaster.  Any comments/suggestions welcome.

thank you
