Eaton is the best value.Get 6.5hp or better. Want to spend a bit more?Buy Quincy,Saylor Beall or Champion,just make sure the electric motor runs under 1800 RPM's and pump under 900. Or if you want to spend quite a bit more, look into rotary screw compressor.

Also, look around to see if you can find any used. I had a compressor for years that was "OK", but not really enough for my purposes. I looked for a while and found a commercial grade used 80cu/ft 7.5hp upright that's built like a mack truck, does 34cfm at 125psi, runs slow and cool, for less than the price of a new consumer grade unit with less than half the performance. You have to be careful to make sure you're not getting a worn out, non-maintained junker. Make sure it's hooked up and you can run it before you buy it, but you can sometimes find deals out there. My old compressor got moved to a barn/storage building I've got which also has 220. Now it's a great utility compressor and my main unit is just what I need for more frequent use.

In my case, the best all-around compressor is the one I built myself:

Like mentioned above, good comPressors are at 1750rpm, get at least 15cfm at 90psi, so it will have a chance to catch up and stop even if you are sandblasting etc. I have a ingersol rand (sp?) and I love it, I got it through Grainger.com.

we sell Atlas Copco's. With that being said, get a 3 phase motor and buy bigger than you think you need. 7.5hp and 80 gallon vertical's are nice and will run forever! **EDIT** 3 phase power is difficult to find in residential applications. If you find a compressor, take into consideration the cost of a converter if 3 phase power is not available at the compressor location.

Whats the differance between a single phase and a 3 phase .
I found a deal on a IR 7.5 HP but its wired for 230/460V 3 Phase motor (wired for 230V
Appreciate any help ..
Is this too much RPM ?

3 phase motors are more efficient, they have a more simple design, they last longer and can produce more torque and HP than the comparable single phase motor. With that being said, most homes do not have 3 phase power. Than can be used, but a phase converter must be purchased in order to do so. A phase converter needs to be sized the HP rating of the motor. For the motor on that compressor, you would need a phase converter that would handle the 7.5hp. As far as RPMS go, that is not an issue. If you shop around, a converter for that size motor can be bought for under $250. Just factor that in to the 'deal' when shopping for a compressor. I will edit my post above to make a note about 3 phase power requirements for residential use.
