Air compressor question....

[alarie]

For compressors, the DA sander is the air hog and is what you have to account for when buying a compressor. I think that 5HP is a bit small and will not keep up with constant sander use, but 7.5 HP and 80 gal will keep up just fine. We have a portable 5 HP gas compressor that will run 1 DA pretty well, but it is loud and you need a good air treatment set up as the pump gets very hot and the air gets real wet.

Otherwise you are going with a fixed unit. Get a 3 phase unit if you have that type of power, as a 7.5 hp 220v unit also hogs juice. The higer cost will soon be covered by reduced elec bills if you are going to use it a lot.
