Our current greatest shop need is the air compressor. We have mostly used portable compressors and I think we tend to over use those smaller units. We r currently down to one PC pancake compressor with with 2.6 cfm output. We spray a lot with our compressors.

Today on CL I found a Speed Air model # 5Z639A air compressor listed for 800.00. The specs show it to b a 7.5 hp 80 gallon. Not sure of cfm output. I cannot find much online about this unit. I have a budget of 1000.00. I have considered an 80 gallon, 5 hp ingersoll rand at lowes that list 18 cfm output. They are asking 1000.00. But I feel the used speed air might be a better compressor.

I have not spoken to the owner of the speed air yet, I would suspect him/her to be possibly negotiable, or maybe not. But I lack knowledge as to what quality this compressor may be and even what the retail price would be for the unit. I do know grainger is the dealer for speed air and I might call them to inquire tomorrow.

And I am not interested in the 450.00 husky/CH 60 gallon models at lowes/HD. We hope to rely on this compressor for years to come and I hope to upgrade a few ROS to dynabrade in the upcoming future.

As always any and all suggestions and advice is welcome. Thanks everyone.

One piece of advise that I can safely give is not to go with the oil-less models they are extremely loud as compared to the oil filled.

On the other hand I bought a Puma 60 gal. oil filled that I have been happy with for the last 7 years and meets the cmf’s needed to run all my air tools and will run any future air tools I may want.

If your going to spend close to $800 for a used one I would say your better off buying a new model that has a warranty with it instead. This just my opinion.

I’m with Greg on this, Jerry. I think new makes sense here. Look to the industrial suppliers, not the retailers. They are usually knowledgeable and can help you with your questions. And, I have found, they’re respectful of your budget.

Sometimes tool repair places, found tucked away in an industrial area, will carry a line of compressors too. Worth checking on.

Since you don’t need portability, vertical makes the most sense. And before you even install it, plumb the bottom drain out to where you can reach it so you can do the diligent draining monthly.

I have a speed air compressor that has served me well for 20 years. The only service I have performed on it is oil changes!

I have the IR 5hp 240v 2-stage 80 gal. It’s outstanding. It’ll bust your $1000 budget, however

If you go with an IR, get it from an industrial distributor. The units made for the retail stores are made to a lower spec even if they have the same numbers on the nameplate.

Thanks a ton guys for the advice. I fully recognize the logic behind going with new, however, with full respect towards Lee and Greg, I am leaning more towards the used speedaire.

I have not pulled the trigger yet. I will explain my train of thoughr and if anyone can caution me further against buying used, I will listen.

I called grainger today. They informed me the unit was recently discontinued but parts r still available. That is a bit concerning to me. They said specs r a 30 amp motor, 7.5 hp, 25 cfm output, 2 stage, 80 gallon. They told me to buy comparable today in speedaire would cost 2000.00.

The owner spoke to me, informed me it has been owned by a laboratory, it is 2 years old, in excellent shape and advised the pump oil has been changed monthly. He informed me the lab upgraded to a larger compressor and his lowest acceptable price is 750.00. He advised he would run the unit for me when I come to see it tomorrow morning. They are willing to hold the unit til I look at it tomorrow.

I agree the IR sold at retail like lowes is likely made cheaper. I also think specs are exaggerated on the unit at lowes. The IR at lowes states 5 hp, 80 gallon, 18 cfm output. The same IR with same specs at tractor supply states 15 cfm output. So with 1000.00 new, plus taxes I would spend 1100.00 as compared to 750.00 for a higher quality unit.

Feel free to look at the CL add to view pics of the speedaire.

This will be the first real compressor I have ever purchased. A guy who used to work in my shop owned a 60 gallon husky with 10 cfm from HD. That was decent. He moved on. I personally only have owned portable units, a craftsman, a rolaire, a dewalt, a porter cable and a makita. So I am excited as the compressor is almost the most used machine in our shop :)

If the Speedair is only a couple of years old and it dependably puts out 25 cfm then I would buy it for $750 and not look back period. When it comes to a compressor the bigger the better and definitely go with Oiled compressors. I have had a couple of oiless and they stunk and I needed to wear ear protection when they were running they were so loud. I now have a CL Devilbiss 80 Ga. 240v. 18 cfm unit and it blows away the Craftsman 60 Ga. I had before it. I t is a big beast but it was well worth the $550 I paid for it. You won’t be disappointed with that Speedair so just go and buy it and enjoy the smile on everyones face in the shop when that sucker powers ALL of your air tools.

I’m inclined to go with the Speedaire, as long as it’s not too old. They do wear out. Make sure the pump is cast iron, (not aluminum with a CI liner). One other very important thing to consider is: has moisture been drained from the tank on a regular basis. Tanks can rust out in a short time if not drained, making them worthless. If the previous owner had moisture separators on it and he has maintenance records, them it may be ok. Offer $500. If he takes it quickly, you know the thing is bad. Another thing; is it a single phase or 3 phase motor?

Apparently you have already bought it or someone else did.
