For air tools yes.

Aye, you need to know what the specs are on your tools, eg., 3.2 scfm @ 40 psi / 5.5 scfm @ 90 psi, and then get something rated similar or higher. Higher if you run more than one tool at the same time as well as continuously. Ginormous tank also FTW!

The last thing you want is for the compressor to kick on every 30 sec (I could be exaggerating b/c for mine it's a few of minutes if I've got my blow gun shootin air out @ 90 psi which is totally unnecessary but fun as all get out, LOL) cuz it's loud and annoying.

Hmmm, maybe you shouldn't listen to me cuz I want one that's the size of a small elephant so I could provide air tool access in every room of my house.

Sander's work compressor's pretty hard.

I think most sanders will run about 8cfm @ 90 psi. I would try and stay well above that for a compressor or it will run all the time,and depending on the duty cycle,could overload the motor.
