My first Sears was a 20 gal. single stage that I flogged for 30 years, never changed the oil, rarely drained the tank - I know, I know. It finally rusted out. Figure it cost me about $3 a year. Currently have a 60 gal. upright, 2 stage Sears that is about 8 years old. Got the HF auto drain valve, since I already proved that I am too lazy to manual drain it. It kept up with everything while I was building my -10, and sees heavy use in my woodworking shop. It is noisy enough that it sits outside my shop, but not so noisy that it bothers my neighbors.

Bought my IR from Northern Tools online. Best price I could find at the time and it included free shipping to my house.

Over the years I acquired 2 Charge Air Pro 5HP compressors. I think they are an older Ingersol Rand product line. One is a 60 gallon single stage and the older is an 80 gallon 2 stage.
I bought them both from private individuals. Actually I traded for the first
The second was a Craigslist ad from a downsizing mechanic.
15 years on the first, 2 years on the second.
Keep an eye open, one will eventually come your way, and you don't have to settle for second best either.
I keep one at home, the other at the hangar.

20+years on my Home Depot (Campbell H) 60 gal upright 208volts help keep the amps in check. I don't use it everyday, but works great when called upon.

Default Problems with mine at first

It's been 13 years since I bought mine from Home Depot. I had a problem within the first couple of months with the start capacitors, I think it was, and called Ingersol-Rand. They told me that they were not happy with Home Depot, as the Depot would buy some components, like tank and motors, from them, and then assemble them with cheaper electronics. I don't know if this is still true. I ended up replacing some of the electronics, but don't remember the details. I generally don't buy high end tools from places like Home Depot anymore.

I bought one for my other shop and it was a craftsman , it lasted 4 or 5 months , the engine blew apart , it was the one the uses o rings for piston rings and they rebuilt it under warranty , it was very ,very loud and would not purchase one again , in my shop were I work out we bought a ingersol rand t6 or t5 I believe about 16 years ago we paid good money for it but runs 12 hours a day 6 days a week and it runs a full repair shop with ease , we did have the electric motor rebuilt about 3 years ago , but that's it , keep them drained and you will. Have it for many years , they do make smaller ones for home use , the sears , or other brands are so loud you can't even think or talk to each other ,

Adam, it sounds like you had an oilless compressor. POS for our purposes, IMHO. Seems to me like they use more energy making noise than compressing air...

That is the max working pressure (MAWP)-the set pressure when it turns off. It is not the rupture vessel pressure. I don't know what that rupture pressure is, but I would assume that the rupture pressure would be in the 2000 psi range or more. Just guessing. It turns on in the 90-100 psi range and turns off at 135 psi.

There is no way that a company could sell a compressor with a rupture pressure of 135 psi.

If you looked closely at the site, then you would have seen that most of the 60 gallon tanks are rated to 135 psi. Again the MAWP not the vessel rupture pressure.

My guess is that the pressure relief valve is set for 150 psi or somewhere in that range.

I work with high pressure reactors all the time and the MAWP might be 1800 psi, while the vessel is rated for 5,000 to 6,000 psi.

Cheers
Ken

Default Eaton Compressor

Eaton Ohio. Check out www.eatoncompressor.com.

I have the 80 gallon, 2 stage, 5 HP, model EC5T80H1PH.

VERY quiet. about 20 CFM at 90 LBS.

We are very pleased with it. If only we had the skills to use it all!

Now this is a real compressor!!! All of the specifications match my Champion compressor that I have had in my shop since 1973.

http://www.eatoncompressor.com/catal...747/206949.htm

Compare price here with Granger..... http://www.grainger.com/product/SPEE...Code=P2IDP2PCP

You will notice it only has a 5 hp motor....... There is a reason for that. Find out why before you purchase your compressor.

The motor runs at 1750 rpm and this makes the compressor quiet by running at between 700 and 800 rpm. Grainger also sells an INTAKE muffler that will reduce the noise even more.

Note..... Looking at the picture, it looks like the unit comes with an INTAKE muffler installed.

Pay the money and be happy ever after.
