New Compressor...

[trent]

No disrespect to anyone, but 5hp is not possible on 110V. Most 110V lines max out at 15A or maybe 20A, and that's 2-3hp.

Don't see any disrespect in pointing that out, I remember the paper work that I had with air compressor I posted about saying it could be wired for 220., I never did that...I knew I'd be moving it around and keeping the 110 connection was better for me at the time.


I am curious if I'd noticed more performance or something if it were wired for 220. ??

I have a really tall compressor. It's 110Volt bust holds a lot of volume. The drain plug is such a PIA to get to, I pit a 90 degree pipe fitting into it, and ran a pipe so that I could just open the wheel, and let the water out. The nice thing is the water does not collect in the compressor, it collects in the pipe, and with my bad back, no more stress to empty it of water, and I do it regularly, as it's much easier. I actually have 3 compressors, as people in my town are so wasteful, and threw 2 away, almost new, but the hose was eaten up by U.V rays, so instead of just buying the hose, they threw these new looking compressors away. One is made for air hammers and the like, it has a big motor, but the two 8" inch diameter 3' foot tubes that are connected to each other.

It's my understanding, that 220V will lower the current draw in half, but it won't increase the power. P=VI

Just out of curiosity last night g ht watched a few YouTube videos of guys with Craftsman air compressors switching wires on motor side from 110 to 220 and vice versa.

One guy did it with motor on his table saw and went into great detail

But no one ever mentioned the plug side, switching it from 110 to 220 ?

Lot of points comments section pointed that out.

I've ran 220 for clothes dryer from one part of house to the other when I switched bedroom into laundry room, I just mimic what was already there.

Kinda fun to get into that stuff....sometimes lol

A multi voltage motor will run at whatever HP and RPM its rated for on the tag regardless of which voltage. As Nessim noted, the higher voltage will run at less amerage. As far as the 240v plug, there are several different configurations that by design won't fit a 120v outlet.

I know there is a difference between 110 and 220 plug, it's just in the videos the wires on motor was as simple as unplugging a wire or two and plugging into a different place....
The videos would have better served its purpose ( for some lol) if they'd shown what to do on the plug side...
many people said same in comments, but I'm sure if it was looked into further it would have been easy to figure out what to do on the plug.

The power wire on mine came set up for 110, but manual said it could be on 220 and the electric cords has 110 plug, but has four wires in it and looks heavy duty with thick wires....
just an observation

Looking down this list, more countries are using 220-240V than those using 110-120V

Had to rebuild it every 12 years or so.

??? Rebuild ? I have (had) the same one and never rebuilt it. At least as old as yours. I beat on it too as it was my traveling comp for work. Even went through a pretty brutal car accident. It now lives at my SILs house. He "borrowed" it and it never came home.

I went to Lowes on a BF sale + military disc and got a upright Kobalt.

Air compressor

It's one of those things I don't use much anymore, but one of those things I don't want to be without

Not much free air at gas station/convenient store anymore, at least the kind you put in a tire..

I bought a DeWalt 30 gallon upright about 15 years ago that was advertised as "quiet". It isn't.
Given the recent improvements in cordless tools I have less and less need for a compressor. Since I don't really do any painting about the only hard requirement is for my lift.

The cordless tool scene is great, service/mech guy at work loves them, says he was skeptical in the early years of cordless.

Has a compressor on service truck, but using cordless stuff all the time.

he's got two Milwaukee half inch drives he using on everything...lol
grinders, drills...just about everything

It would be cheaper to run at 220 volts though.If you plan to run it a lot.

Is that the case? The way I understand the "work done" would be the same either way so the watts consumed should be the same.

The 240v in the US is different to a lot of the rest of the world. The US uses 2 phases together & takes the different between the two to get to 240v whereas the rest of the world is 240v on a single phase back to neutral.
In the UK the 3 phase supply is around 600v from memory.

This shows a diagram of the practical wiring side of it:

So only advantage to running 220/230/240 is less draw amperage wise??

Easier on equipment?

As Dan says, the POWER input is the same, so I don't think it's easier per se.
