Seriously, if you have the cash, a way to move it, and a place to put it, that will be the last compressor you will ever need to buy.

Make sure that is a single phase motor. (2 phase??? Never heard of that one.)

BTW, Mine was a bit of a pain to unload off my trailer. As tall as it was, I ended up moving it in pieces with my engine hoist. With the 120 gallon tank, that thing is probably 750-1000 pounds. You won't want to move it after it lands in its spot.

I feel like the advantages of actually being able to move your compressor without a forklift might be overlooked.

2 phase is 220/240v

I've never heard it called that. Around here, 2 hots and a not, is single phase. Anything with 3 hots and a not, is 3 phase.

Harvey, I agree to a point. My Quincy hasn't moved in several years. I did keep my 2hp for mobile use, but it hasn't been turned on since the big one came online. Mobile use has fallen on a little pancake compressor I used to keep on my trailer for race tires.

In the US, 240vac in a residential setting is single phase. There used to be a thing called two phase but it's essentially obsolete. https://en.wikipedia.org/wiki/Two-phase_electric_power .

Good advice.

I am used to Theatrical Lighting.. so my education is biased towards that... but I did learn something interesting. While 2 phase is obsolete, Philadelphia has many buildings in centre city that are permanently wired for it.. therefor PECO has to supply two phase to them

Two Phase Wiki

As for "two hots and a not".. That should be 240v as each leg is only 120v.. unless you are drawing both hots from the same leg

It's all about the tank size.. If the air tank is big enough you can work with a flashlight battery (Almost) My big air compressor threw it's belts this spring and I've been too busy to replace them (and find out what caused them to be thrown) So I plugged in my tiny little 1/2 hp 35 year old Chinese air compressor into the big tank and suddenly it's nearly Thanksgiving and fixing the old compressor is still down on the bottom of my too do list..

I did that to mine, Frenchy, I have a big 50 gallon upright that died. I took the motor off and made it so I can fill it from my small dewalt... makes a great airtank

I got a two stage sears vertical tank that that's served me really well. Not as quiet as a industrial unit but much better than the smaller buzz box units. Small sand blasting project or painting with one of those disposable HF guns is no problem. I have not tried a DA. If I remember it is rated at 10CFM at 90 psi.
