I wouldnt count on it. $900 really isnt a higher end compressor. I gave a quick search but could find no reference to the actual compressor RPM on the IR site. Maybe someone can confirm what speed these compressors run at.

My brother in law recently got one of the 80gal IR compressors from TSC. Overall it's a good quality unit for the price. They use a 3450 rpm motor and I'd guess the pump is probably running 1000-1200 rpm. So it's not as bad as the cheap craftsman direct drive compressors but it's not a 600rpm unit either. Sound was not obnoxious but I've heard quieter compressors.

Very true, I didnt mean higher end of two stage reciprocating pumps. Higher end as compared to what I have and most single stage compressors.
I have found that IR is not listing the pump speed. But on these two less expensive models I am comparing the motor speeds are 3450rpm.
Something else that I have found out is that the 1725rpm motors are on units around $1799.99.
That is just not in the budget. Anymore info is most welcome. But I want to keep the cost to no more than $1300.00

That's the same one I have been considering. Any of these machines are a step up from my campbell hausfeld single stage.
I have also been looking at quincy brand compressors also. I like the motors better(baldor), I think the IR's I have been comparing have emerson motors.

An old used Quincy pump will out last a new TSC or Sears any day. Quincy has great parts support and are good industrial pumps. It is tough to find ones with out 3 phase motors but they are around. If you can find a Curtis, Gardner-Denver or an older IR they are all good pumps as well. The cast iron pumps are hard to beat.

These compressors I am looking at are not TSC or sears brands, they are ingersoll rand.
Tractor supply just sells them.
Been looking for a used old school compressor for a couple years. Everything I have found is 3 phase, or to far away and shipping costs makes it unreasonable. To replace the motor to a single phase baldor motor is not cheap.

During a search I came across eaton compressors. They seem to fit the bill for what I am looking for in a compressor. Less than 900 rpm pump speed, all cast iron, and a great warrenty.

THis may or may not matter to you, but Eaton has a reputation for false advertising. Matter of fact they threatened several people and web forums for publishing that their product was falsly labeled Made in USA. http://www.hotrodders.com/forum/eaton-compressor-threatens-sue-me-over-made-china-compressor-post-143953.html?
Too bad you wernt at the auction i went to today. A very nice 5hp 2 stage (binks i think) compressor sold for $300. And a AWESOME Atlas Copco Airlet LE8 (28CFM) compressor went for 400!!!!! I would have been ALL OVER THEM but i was saving my cash for a plasma.
Turned out the plasma went for big money (too much). Someone STOLE those compressors. I should have bid on them. Hindsight is 2020.

Thanks for the input scooby. I have been really searching hard and I am going to look at a 1980's kellogg american later this week.
I passed on a IR 7.5 hp 80 gal. It was used a couple hours according to the owner and was still strapped to the shipping pallet. The motor speed was 3450rpm and they were asking $750.
I am going to pass on the eaton compressors and try to find a good used compressor locally.

Im not necessarily saying Eaton is a bad compressor. Many have them and are quite happy. 1ust some of their business practices leave a lot to be desired.
Good luck on your hunt. Do you ever get a chance to get to any auctions? Smaller auctions are where some of the best deals are found.
