Guys,
I'm finally breaking ground on my garage after moving 2 years ago. I left a MADE in the USA big daddy compressor at my old shop. Hated to do it, but had to.
So, for the new shop, what are the better brands out there? What should I stay away from? Options I should get? I will be using it for mostly mechanical work. If I paint any, it will be small items. I would like to be able to run two 3/8" drive ratchets with it at the same time. That will be rare, but nice to have the capacity should I need it. My 2-post lift is electric. So, what size would you recommend? Lastly, what are some prices of said units, so I can budget accordingly.
Thanks!! Randy

Dixie....the first question is do you have 220 volts available??? That changes everything.
Sure, I'm building the garage now. So, I can install whatever service I want. I plenty of power on tap.

Is single phase good enough?
Yes it's what you want in a residential setting. It'll cost a little more up front but then you won't have to deal with a phase converter.

For a constant supply of air when needed your best bet is a two-stage compressor. They supply significantly more air (cfm)than a single stage and cost a bit more but they are worth it. The sellers like to tell you about horsepower but CFM is what's important.
I'm pretty sure he will go 2 stage?
He asked about electrical requirements and usually around residential areas you only have single phase power. And most large compressors come standard with a 3 phase motor because it is cheaper than a single phase motor. If your in commercial area with 3 phase power your best bet to order your equipment for 3 phase power and use it.

hi Randy! this has nothing to do with an air compressor but if you're doing electricals from scratch plan on enoth for a welder too. even if you don't weld now ya never know!
I bet Randy will have plenty of power and panel space for anything.
20 years ago I had my 100 amp box taken out of my house and had a 200 amp box installed in the house. Then they put my 100 amp box in my garage. At first it only did one 30 amp 220 plug for a large free gigantic window AC unit. Even the overhead lights feed from the house because that's how it was originally.
Since then I have installed about 10 circuits over the years, 2 50 amp 220 welders plugs, 3 30 amp 220 plugs for pressure washer, hot tub(GFI), and window AC. Then I have a 30 amp 125 volt plug for my RV in the drive and lot's more. Have like 4 20 amp plug circuits. Most of it is to code as I hang out with 2 electricians friends and have done plenty of electrical work in the past at work. Once you have the service anything goes just as long as it's single phase.

My experience has not been so positive, Puked 2 pumps and the control switch in 4 years. had to haggle a bit on the second pump and switch but they finally buckled. They said the units are only rated at a 30-40% Duty cycle if I remember correctly. so do your research. Had I know that I would have chosen a different brand if you run a blast cabinet that means 3-4 minutes of run time and 7 minutes or so of cool down. And yes it has been serviced regularly. We don't run the unit that hard except when using the blast cabinet occasionally. My 1992 Sears 2 stage never whimpered and never failed in 17 years. Thought I was stepping up with the eaton. ???? next stop QUINCY!!! PERIOD!!!
