get 7.5 hp 80 gallon tank 2 stage compressor you will need about a 40 amp breaker.This
will do sandblasting and running grinder and da.Get a high cfm rating like 19 or more at 90 psi.Just went through all this
This is better way than the 5 hp/60 gallon setup. You can't go wrong with more capacity and pumping power. I currently run 2, 5 hp/ 60 gallon compressors tied together. It works pretty good, but runs a lot when DA ing
and grinding. Also have to be mindful when painting an allover. I am planning on upgrading sometime in the next year.
