You said you didn't agree with the blanket statement that the 60 vs 80 gallon didn't make a difference and I simply explained what I meant, that it was not a "blanket statement" that it made no difference at all. As far as the 60 gallon vs 80 making a difference while painting that can be a toss up also, you run a bit longer but then you also wait longer IF the compressor has to catch up, if it doesn't have to catch up and can keep up with the spray equipment then it makes no difference. The idea that an 80 gallon tank is going to provide cooler air than a 60 gallon is something you seemed to be saying and that is simply not going to be an issue since it is the amount of time the pump runs in a given work period that will cause the hotter air, when running that sandblaster for 15 minutes (or any tool for more than one run cycle) the pump will run the same amount of time regardless which tank you have and THAT is what heats the air. Having an 80 gallon tank instead of a 60 gallon does not mean the pump will run less during any given work period and it would be the same even with the 20 gallon you mention. You said that with a 20 gallon tank when painting you would have the same issue as you do when sandblasting with the bigger tank but that's not so, when sand blasting the compressor runs almost continuously and accumulates a heck of a lot more run time during the work period than when painting for the same work period. the frequent and short start/stop cycles of the smaller tank would cause some cooling problem but not for the same reasons as sandblasting with the bigger tank nor would the problem be as severe. If you paint for 30 minutes then the compressor will run the same amount of time whether has a 60 gallon tank or an 80 gallon or a 20 gallon for that matter.
