I am looking at this air compressor at Tractor Supply - Ingersol 2-stage

[DXN1EL]

Can you really get 7.5 hp on a single phase line? How many amps would that pull on startup?

Products: AC Motors: GDL1615T: Baldor Electric Company, a leader in energy efficient electric motors, linear motors and adjustable speed drives industry
This 16HP is the biggest I have found that can run on single phase of course is not going to be on a compressor since is expensive
71-62 AMPS

Here is a really nice Speedaire...
I just posted it to show what is available on search tempest if you just look...

Actually Quincey made a 10hp single phase air compressor, not sure if they still do. They also make both splash and pressure lubrication. A 10hp single phase motor is going to draw 40 amps and up to 80 on start up. A 7.5hp single phase will draw 32 amps with twice that on start up.

It makes the single phase

Look like CRAP :cool2:

Before I bought that I would get one of these. At least some of the parts are American made. Plus it's cheaper and the pump runs at 800 rpm.

Speedaires are nice.. had several running in factory setting for years 6 days a week, 24hrs a day. Nice screw compressors too..

What if we had to spend under $1000? Cause thats the top end of the budget. New only, I can't tell how many hours are on a used compressor, so used is a big unknown. Sure, they can be rebuilt, but I would have to factor that into the price up front. My Puma looks brand new but is 25 years old and has run many hours.
I am 54 years old, so need compressed air another 20-25 years. My Puma single stage cast iron v-twin lasted that long, so I am hoping for a repeat.
I am assuming I would get 20 years lifespan out of the IR, since it is larger capacity than my Puma single stage. If noise is the only objection, I have the option of installing it in a building separate from my shop, and about 24 feet away. The more I think about this idea, the more I like it. There is 100 amp service in that other building too, so the compressor could be on its own power (separate from my workshop 100 amp service, both buried direct to the pole-mounted transformer). Air distribution is not a big problem, since I was going to distribute inside the shop anyway, and was contemplating taking a line over to the other building. So I would be doing all the same plumbing for distribution, but the compressor location would switch from one to the other building.
That other building is not heated, so I would have to make sure I was running synthetic compressor oil. It will have to start at as cold as 10 below zero I assume. Guess I better ponder that concept a while longer...
Meanwhile, I plan to call the local TSC store and ask the manager to run over and read the motor information plate on the IR to me, so I don't have to drive down there. And I will look at my Puma motor plate information tonight too.

IF I go over budget somewhat, this Quincy looks like the closest to compare without going crazy overkill:

I noticed they use a cast iron crankcase and an aluminum head. I havent really had great luck with that combination of materials in automotive applications. They give the pump rpm as 1310, and list it as splash lube.

I mean the the 7.5 HP Champion is the best 80Gal ever.! That pump was designed to be run at little higher RPM with a 15Hp motor, It was slow down to 575 RPM with that 7.5.

The 120 Polar is a good compressor,

Sounds like a plan.. In the end, if you dont have the budget, you dont have the budget and that IR would then become a good choice.

There are several brands out there that sell the same Eaton style pump compressor. I'm not sure if there's much of a difference in quality but the Polar air is the actual Eaton company (still a Chinese made pump). I even think that the Emax brand is related to the owner of Eaton. The Champion compressors say made in the USA but to legally say that all you need is something like 60% of the product to be US made. Eaton ran into that problem when people assumed that they were 100% us made. I can't find where Champion states that their pumps are US made. Since their warranty isn't as good as others (a pro rated 5 year warranty) I wanted to read that the pumps are US made. I don't mine made in China but if I can get a product for near the same price made in the US then that's the direction I lean. I like my Speed aire but I bought it used from a friend for a great price. But being a Granger product it's most likely over priced so I'll not be getting a new one.

I think almost any belt driven compressor you can find in your budget will last about the same amount of time. IR will give you good chances of getting parts if you need them. I like Quincy but I doubt the one you listed will give you more for your money. I thought I remember reading that Quincy has their pumps made overseas (like everyone else) for the lower end models.
