Quality air compressor needed.

[Countyroadtrailers]

I'm needing a 7.5-8 hp air compressor (need 24-30 cfm) for my new shop.

I was kinda set on IR and ready to order one until I saw a almost big enough one at tractor supply. One compressor was made in India, one in China.

Are there any more decently priced compressors that I should be looking into budget is circa $3000 and I will be purchasing a refrigerated air dryer as well budget is not more then 1500 or so for that. Am I weird for wanting a USA made or English compressor. I guess it felt weird that they had two identical compressors with the pumps made in two separate countries

I always recommend an older USA made compressor that may need a little work.

I have the IR 2475 and love it. Should be about 1500-2000.

That's the one I saw with both a Chinese compressor on one and a Indian one on another. .


Where is yours made?

Found Quincy compressors today, allegedly all USA made.

Anyone have any experience with these?

Quincy QR pressure lube is the best you can get. Some of their cheaper ones with the QT pumps are good too. I would avoid the vertical twin compressors that use the bare aluminum ABAC pump. ABAC is an Atlas Copco company, and Copco bought Quincy a few years ago.

Can't go wrong with a Champion.

Look at DV Systems, Kellogg, Curtis, Saylor Beall. Curtis is a Chinese company now, but their Masterline pumps should still be USA made. LeRoi Lifesaver pressure lube pumps are as good as the Quincy QR series.

These might be near the limit of your budget though. These are all top-quality compressors and the price will reflect this.

You might look at the Eaton compressors as well, if you aren't going to be running them flat out all day sandblasting.

This is the information I needed. Since you seem to be knowledgeable what about the qp Quincy pumps? They seem to split the middle between the qr and the qt and are less than my price range and still pressure lubricated. Have you any experience with these? I'm going to call a distributor in Alabaster Monday about them. I can't seem to find what the qr circa 7.5 pumps run but I'm going to ask then as well.

Not sure at this moment as it’s at my other property. I bought mine about 18 yrs ago so who knows but either way, I’ve never had an issue.

Is this for commercial use? For a $3k budget, I don't know if you can get a new 7.5 HP pressure lubed unit . The Quincy QT 7.5 sells for ~$2500 and is splash lube, but splash is fine. I have this unit. Lots of threads on this so a search will help. I think Quincy may use some imported motors now. Mine is 15 yrs old with a USA Baldor. I'm happy with mine but if I could do it over I'd look for something with a slower pump speed as it's loud- but it was already more than I could afford at the time

 

[md21722]

The only pumps still entirely made in the U.S.A. the last time I checked are Saylor Beall.

For your needs and budget I would look towards a Saylor Beall 7.5 HP with the 707 pump, or a Champion R Series 7.5 HP with the R-30 pump.

A lot of people like Eaton/Polar Air. Their pumps are typically Saylor Beall import knock offs.

The nice thing about the Champion R Series is they are easy to service with no special tools required. Also, there is no head gasket or valve plate. The disc valves are under the manifolds which take a 9/16" wrench to remove. They've been making them way since the 1940's. They are very lost lasting pumps.

I agree a little about assessing the intent. About any decent unit will last longer than the owner in most cases. Most of the 7.5 are the same pumps as 5 with a bigger motor and pulley on them, speed is faster, they make more air.
I am a 5 hp fan. If I can make it on that I do, cheaper, last longer running a little slower.

Mixed use. I will be feeding my polyurea machine during the day and using it in my hobby shop side when I'm off or slow.

I just got a quote back for a Quincy qp pressure lube for 2948 for the pro series and 3881 for a Max.

I just haven't read much about the qp. I always read arbout the qr as being legendary and the qt as being pretty good.

Unfortunately the 5hp doesn't make enough cfm for my needs. 7.5 puts me right at the money and I'll have some tank volume in case someone else needs to air up something etc.

Single-Phase or 3-Phase? 3-Phase are cheaper.

Also throw Jenny into the mix:

https://www.aircompressorsdirect.com/Jenny-U75B-80-230-1-Air-Compressor/p3833.html

I think the "U" pump on this one turns around 600RPM. The pump alone is 340 lbs! Total weight of the unit is 800 lbs, that's almost twice as the consumer-grade units commonly sold everywhere.

Well just got off of the phone with Quincy. There 7.5 hp air compressor uses WEG motors not Baldor.

I swear I can't win for losing lol.

Looks like WEG would be made in Mexico or Brazil....I guess I'm better with that then a Chinese compressor

Our Champion compressors have been 100% reliable. No head gasket, Baldor motor, quiet running. Baldor motors are more tolerant of improper voltages, if that is an issue.

 

[sberry]

I been running a splash every day.for 45 years. Use it every day some and at some points used it a lot. Painted continuously for 3 or 4 years, maybe more. Lots of wire wheel, sanding, some grinding and some sandblast. Wasn't taken great.care of at a couple points. Sat in a very humid building.

Yes, this has been discussed in a past Quincy thread. Follow up posts stated that WEG was good quality. Again, I would do a search.

Those big Jennys are Kelloggs. That's a 452. Very good pump. It's also good to 10hp.

Our 2500hp turbo blower has a WEG motor. I have seen them everywhere in the last 25 years. They are a good, well priced motor.

The QP should be a fine compressor. I have no first hand experience with them, but the QT was a good unit, and pressure lube should make it that much better.

The QR series 7.5hp should be a 340 pump and is out of your budget for just the bare pump I would guess.

WEG is a Brazilian company that literally digs the motors out of the ground. That is, they mine, smelt, and manufacture the copper, and mine, smelt, and cast the iron. They didn't use to alloy steel, so the motors were all cast iron and heavy. I don't know if that is still true. I have a good friend who has an electric motor repair shop. He says WEG stands for World Electrical Garbage. I personally don't have first hand experience with them, and have never pressed him to cite chapter and verse. Maybe someone else can shed more light on the subject.

Well after thinking on it for a bit I now have a Saylor-Bealle on order. I hope it will be a good one.

I did a ton of research on this topic recently and concluded for the money there wasn’t a better value than Eaton (Polar Air) for my 10hp. I would bet if you compare their 7.5’s to competitors, you may agree with me.

You can't go wrong with a Saylor-Beall ...very dependable pumps. Did you order the pressure lubed or splash model?

BTW, Baldor was sold to ABB a few years ago. I have heard from the owner of a motor repair shop that they aren't as good as they once were. I have never had any issues with them and still prefer them when shopping for a new motor.

I ordered the pressure lube one, the 707 pump which should allow me to run a 10 hp in later years if I so desire to. I like the idea that it's really not a sped up 5 how pump and that they use the same on a 7.5 or 10. I got the pressure lube as when I'm spraying this air compressor will be used as continuous duty use and when I'm not it couldn't hurt to have a pl model lol. 120 gallon tank with the mag starter

I would assume then that you also got the fan cooled aftercooler? I really like SB's idea of placing the fan on the motor shaft rather than just utilizing the pump flywheel to draw cooling air for 2 reasons, first, you're not heating the air used to cool the pump and second, the motor is turning at 1725 +/- RPM vs 600-800 pump RPM.

Another item to seriously consider is ordering the compressor with 'dual run' controls. It sounds like you use a lot of CFM while spraying, and even though you have a 120 gallon receiver, you may be calling on the pump to cycle more than 6 times an hour and if so, it should be set to 'continious run' to allow the pump to cool between cycles. Along with pump cooling, it saves your motor as starts are much harder than continuous running...especially if the motor is single phase.

Lastly, you need to install a GOOD (read Bekomat) automatic condensate drain and you're set for life. I would suggest that after pump break-in, you change over to a synthetic compressor oil like Royal Purple or Amsoil since you run your pump continuous.

If you are looking at a high output low RPM pump (575 RPM = quiet and will last a long time) then the Champion HRV7-8 7.5 or VRV7-8-1P-230 is also worth checking out. I would get the after cooler no matter which compressor you get, makes a big difference in the temperature and pulls out the moisture. I purchased a 5 Hp Champion from Pacific Air, its been working very nicely for about 2 years, quieter than the Curtis compressor that I previously had. Get the automatic drain, these also need rubber isolation mounts. Have had good service from Pacific Air, had a tank check valve leak and they replaced it under warranty.

On motors, Champion was having some problems (QC) with Baldor motors, and switched to Marathon on my compressor. Many of the components are made outside the US, and assembled in the US. The WEG motors are also quite good, worth looking at the warranties on the compressors and also reading about if the manufactures honor the warranty. Been some issues with Quincy when I was looking at compressors, also comes down to who you buy it from. With Quincy, you often have to buy one of there service kits/oil change to get the extended warranty.
