Air Compressor

[Robs66Coupe]

4 hp 18 gallon Crafsmen. The side says 8.4 scfm @ 40 psi and 6.2 scfm @ 90 psi. It seems like it struggles to keep up with my 1/4" angle die grinder. Do you think it'll keep up with a paint gun and a DA sander or should I look into procuring a new one? If I need a new one, can you guys recommend any that are good for a decent price?

That's puny. You need a 60 gal minimum tank and 9 cfm at 150 psi to work a sander. Sanders and blasting cabinets are about the most stressful item on a air compressor.

+1 and as far as recommendations go, go as big as you can afford. I have a 33 gallon craftsman, and regret buying it every time i try to do something.

That's what I was afraid of. The one we had was one my grandfather bought a couple years ago. When he passed, my grandmother didn't have any use for it, so we took it. I guess I'll have to start looking around...

I would 80 gal min. if you are going to paint. Rich.

Do you guys have any recommendations of where to look and what price range this should be about?

Tractor Supply runs pretty good deals from time to time.

I have a 60 gallon at the house and it runs hard to keep up with die grinders and da sanders. I would recommend an 80 gallon as well.

Made me want to just buy an old IR 175 and be done with it.
