Air Compressor size required?

[88Stanger]

So I am just trying to get a feel for what size air compressor is needed to run air sanders, grinders, and so on. all the typical equipment for a complete frame off build. Currently I have a 30 gal 1.3 hp compressor that just hates to run air grinders/sanders, so its time to get a new compressor. I was looking at the 60 gal upright sears professional series, anyone using this one and have anything to say good or bad about it?
Thanks for taking the time to reply.

I had one of those once and the compressor burnt up.

Replaced it with a Campbell Hausfield from Harbor Freight about 10 years ago and never had a minutes trouble with it. It is also a 60 gal. upright.

Stay away from the Oil-Free compressors, those are for occasionally airing up your bike tires, lol. Seriously though, they burn up pretty quickly especially if there is a lot of dirt and dust around. Get a nice Ingersol Rand or Campbell Hausfeld 5hp upright (saves space) with a separate pump and motor (with a belt connecting the two). If you have a little more $$$ you can pick up a Speedaire, BelAire, Quincy or Champion compressor. I know there are more but that's off the top of my head. If you are on a budget browse through your local Craigslist and pick up a good used one. I'd stay away from the Harbor Freight compressors if it were me.

Make sure to get a Single Phase compressor unless you have the capacity in your electrical box to accommodate it, which normal residential homes do not have. Also, try to get a 220v unless you don't have 220 in your garage (dryer plug). Also, pick yourself up a nice water trap.

Hope that helped some.

I agree with everything. A 60 gal, oiled, 220V, single stage is the minimum you want. Don't be afraid to buy used, but do your homework, they are inexpensive new.

I gave under 200 for this, used. It works perfectly.
