i'm looking to upgrade my compressor. its got a 25 gallon tank that is no longer sufficient. i'd like to get a 60 gallon or bigger. (or a tank the fills in less than a minute) but i dont have 220 and i dont have a way of getting 220. are there any compressors out there that run on 110v? or for that matter if i get a used compressor that has a bad motor could i put a motor on it that runs on 110v? if i have to hard wire it thats fine its just i have no way of running 220 to my garage, it would cost far more than its worth. i thought about just adding a second tank, but the compressor takes for ever to fill the standard tank as it is. any help would be awesome!
If you use an inverter (Allen-Bradley PowerFlex 4) you can buy a three phase 230 volt compressor and operated from the 15 amp 115 volt receptical you're now using.
A 1.5 hp 3 phase 220 volt compressor will blow the doors off - and.... you can buy a used industrial compressor for pennies on the dollar!
I paid $25 bucks for a 7.5 hp, 200 psi, three stage, intercooled, 150 gallon compressor..
I don't think you are going to have any luck finding a 110 motor or compressor that will fill a 60 gallon tank in a minute or less. that would be one heck of a pump and motor,and definitely not 110 volt. Unless you were talking about from just 90 psi until 120 psi when it kicks out,then that MAY be possible for 110 volt,but even then that is a stretch.

Could you elaborate on this please?
if i understand correctly, i could use a power inverter, and NOT have to run 220? where and more importantly how much will an inverter cost?
and where are y'all finding compressors for less than 500 bucks? ive been looking for a couple weeks and havent seen a reasonably priced compressor yet!

i didnt mean fill a 60 gallon tank in under a minute, a meant a 25 or so gallon tank. sorry for the confusion.

Then select the area you're in, and start hunting. Maybe even put up a want ad.
It's also not an issue of just instantly finding exactly what you are looking for, you have to hunt. It took me a good three or four months to find my setup at the price I was willing to pay, I could have had a dozen other ones in the sub-$250 range in the meantime. Instead, I have under $50 invested in mine.
yeah thats my problem, i can never wait lol. i'm going to look at a few this week. one is in my price range, but i dont know anything about it yet. im hoping to find a diamond in the rough. lol. i can hope cant i?
Correct. With 110 volts you can run up to 1.75 hp 3 phase. by slowing down the motor you can run larger horsepowers as well. The inverter will cost a couple of hundred dollars, unless you find a deal. Your local Allen-Bradley distributor can help you work something out. You can use it to run all your hobby stuff. (just one at a time). My whole wood shop is 3 phase. Because so many people do not have 3 phase, you can pick the stuff up easily and for pennies

hmmm for that price it might be cheaper for me to run 220v service to my garage.
now how can i tell if the motor is 3 phase or single phase? electric stuff like this is not one of my strong points. i have no idea what the difference between single and 3 phase is.

According to the refrence books I have a 240 volt 1.5 horse motor takes 7.6 amps at full load (1824 watts) with a 22amp (5280 watts) inrush for start. Running a transformer from 120 to 240 you still need the same total watts to run it no matter voltage. Don't forget there is a 2 to 5% power loss figured for transformers. Basic power formula is volts X amps = watts. I'd see about a dedicated line or tap the wife's dryer line. It should be a 30 amp 240 circuit. If no dryer connection then you may just have to get the wire ran. It can be run in an attic. You'll need #8. 3 conductor.
Motors will state the number of phases on the nameplate and to not have starting capacitors
30 amps of 220 volt single phase, depending on your situation, could cost less than 100 bucks in material
The modern AC Inverter provides a unity powerfactor and the motor is decoupled from the service. A PowerFlex drive on 115vac with a maximum current draw of 13.5 amps will run a 1.5 HP 230 volt motor all day long. No transformer is required. And there is no inrush with the drive.
