Suggestions for new garage compressor

[Jcrapola]

I was given a shockingly large bonus at work this year (yaaaah!), and am now in the market for a new air compressor. My budget is Under $2500. I am replacing a craftsman 6.5hp single stage oilless vertical from the early 90s. It doesnt run like it used to anymore, and it has always been objectionably loud.

I want a 60 or 80 gallon 2 stage compressor. I would like it to produce 18 cfm or better, and i REALLY want it to be american made.

Im looking at Quincy currently. Is the pressure lubricated Quincy model worth the extra $500 over the splash lubricated version?

Also considered the Eaton Polar air (i know the pumps are made overseas), and ingersol rand.

Any thoughts or opinions from people that have purchased a large garage compressor would be greatly appreciated!! Thanks!

 

[pacemade]

I see a lot of people combined tanks, what are you planning on doing with your old compressor? How large is its tank?

 

[pacemade]

And congrats on the bonus!

 

[jonjon1]

Great job on the bonus!!!


To me this is a no brainer...

http://www.zoro.com/ingersoll-rand-electric-air-compressor-2-stage-24-cfm-2475n75/i/G2885382/

I have a coupon code that is good for 1/4-1/8 for $20% off that will put you around $1750. Its 25cfm ish, I have 2 of them, they run great, quiet, nice units... PM me if you want a code, I have 2 and I am only going to use one... They have a 25% for may 19th I think in the calendar too, but that is a long ways away, lol...

if you want to spend more money add one of these http://www.zoro.com/ingersoll-rand-compressed-air-dryer-25-cfm-75-hp-115v-d42in/i/G0553445/ after the 20% off it will be around $800

If I was to buy one, it would most likely be Qunicy. The new IR's look like garbage with the Indian cast play dough looking pump.

 

[MacMcMacmac]

I'd get a Champion.

 

[jonjon1]

If I was to buy one, it would most likely be Qunicy. The new IR's look like garbage with the Indian cast play dough looking pump.

they look fine to me, I have 4 of them 2475's, they run awesome(two are in use, the other 2 are almost hooked up), quiet, make a ton of air, don't care if they are spun fast or slow they just last, the parts aren't too bad if you need to fix them, they have a decent warranty, and don't get super hot...

I also have a quincy as does my brother, and they also work great, the inline pumps seem to run a bit hotter, maybe due to less surface area and the second stage touching the first stage in the same head..

IR is all cast iron, my quincy has an aluminum head, and it still gets hotter than the IR's, it s a bit louder also and spins slower so not sure why, also I have hour meters on everything and the quincy always has dirty oil, the oil coming out of the IR's is always still purple, not sure why. I think they are both great pumps, but when making a decision, I would let the spec speak, and I am a business man so I want to know I am getting the most for my money..

24cfm at 90psi for $1750, Quincy is $600 more for 23.8cfm at 90... And while I will say the quincy is made better, I own both (quincy 5hp, ir 5hp, and ir 7.5hp), it is heavier to move around, BUT I wouldnt say it works better or do I expect it to last longer. I actually think the ir will last longer due to the clean oil changes, the lower heat, and less vibration. Either will last most home users 5 lifetimes, so longevity is a moot point, both are american companies employing americans...

PS, I was told the India made T30's are made better than the older models, Steve a technical rep for IR, explained the machining practices are all modern and state of the art now, they have a tighter clearance tolerances etc, and he says its the same quality metals. Although he admits teh painted finishes are not as nice, they switched to a matte black vs the old IR grey semi gloss, I agree, I have a grey pump and all my others are the black matte, the grey is a nice finish...


ANYWAY, don't be afraid of the IR's, they are decent (t30's that is, I am not a fan of the inlines)...


I think if money wasnt an option and I ignored everything else and just wanted a real nice compressor http://www.ebay.com/itm/Champion-7-...364604?hash=item2ca62a81bc:g:jawAAOSwv-NWU4al
them are awesome, I personally just couldnt spend an extra $1000 when I know the ir will do the same thing (basically), BUT this one has the auto tank drain, after cooler, HUGE V pump, and looks really cool with the cut down 120/80 gallon tank.. Its a sick compressor...

The psi lubed quincy is around the same price, BUT, speaking to a few compressor gurus, the psi lubed units are about the same longevity as the splashed units, and in some cases the psi lube can be more issues...

 

[Antique Engine]

My Champion meets all your criteria and it is made in USA.

 

[Dick in Wisconsin]

Rolair is American made in Hustisford, WI and very reliable. Check them out.

 

[Finky198]

The Ir is great. I installed a 2475N7.5 80gal from tractor supply they offer discounts on occasion... Worth a shot retails $1999+ tax...for 24cfm @90 so its in your price range. I saved a bunch as mine was scratched I talked them down 25% ..

They look fine and are very nicely built

Best of luck.

[Roberts210]

It sounds like you are not going to be using this as a primary work compressor, so how about getting a good, 2nd-hand USA compressor? Your money will go further.

 

[motofool33]

schultz compressor u should beable to get a 7.5hp two stage for 1800-2300.

champion, quincy, saylor bell,

Actually Ingersoll Rand is an Irish company. It moved head office from the Cayman Islands a few years ago. We all know what a hotbed of engineering excellence the Cayman Islands are. Keeping Uncle Sam at bay I suppose. All perfectly legal I'm sure.

There's nothing wrong with a T30 pump that running it at sane speeds wouldn't solve. They slap that magic oil in them then claim a 100% duty cycle and spin them to the moon.

I don't believe for a second that those petal valves are better than the original concentric disc valves.

i have an old school T-30 its nothing like the new T-30 u can buy at tractor supply. big differences

 

[jonjon1]

Another option would be to build your own..

http://www.ebay.com/itm/L1510T-7-5-...012219?hash=item3aac8cce7b:g:XMUAAOSw-W5U0~g3
that could still be under $2500 after a $20 check valve, $65 sheave and bushing, $50 pressure switch, $100 mag starter, $7 200psi blow off valve, $4 easy start valve, $50 stainless plumbing, $18 belt, $105 pulley cage, and some wire/fittings/hardware...

Its a lot of work though, lol... I think the kellogg 120ga with the 452 is over $3000 and weights like 1000lbs!!!!

Which models are you comparing? For example I have a 2475 and a 2545 both modern t30's, and totally different, the 2545 is twice the size and has built in unloaders... I also have a 242 on an old 5hp horizontal which would be the replacement for the model 2475 (which comes on the 7.5hp I linked above). Putting them side by side (MY 242 is marked 1982) the differences ar very subtle, the 2475 is a bit larger, and more robust, feels tighter than I ever remembering the 242 feeling, that that still runs great, its in my fathers garage under a work bench covered in saw dust for the last 4-5 years since I retired it (the horizontal tank was getting tough to deal with as we were expanding).

There is a small t30 I am not sure of the number, I dont own any of them, but they come on the 3-5hp IR's and they are $1200-1500, I have yet to hear anything bad about them. I know IR had issues with the ss5 pumps, but have heard that it is remedied, it was a gasket/bolt issue.

I am curious as to which t30 you have and are comparing it to? when I look at the two I don't see much difference...

i believe mine is a 242, the t-30 they had at my previous job looked just like this one in the link http://www.tractorsupply.com/tsc/pr...-gallon-two-stage-air-compressor?cm_vc=-10005
loud as hell fast spinning motor(3450rpm?) on it junk.

my t-30 runs nice n slow with a 1750rpm motor

loud as hell fast spinning motor(3450rpm?) on it junk.

my t-30 runs nice n slow with a 1750rpm motor

this is the 242

here is the 2475, better head design, 30% more cooling area, larger/longer intercooler coil between the first and second stage, redesigned oil drain system, redesigned rear plate with more bolts holding it to the block, more aggressive flywheel cooling, better designed crank case vent, less rotating mass (uses less energy to spin the unit), etc... It makes more air and lasts longer...



Like I said I own both, and I have to say the 2475 is a better pump, and I will BET its a good clip quieter than a 5hp 242 t30, especially if my memory serves me, my 7.5's are about the quietest non rotaries I ever heard...

Now as for the rpm, I have tested them, I think the 7.5hp is quieter than the 242 and noticeably so (I havent tested teh 5hp 242). Sure the 242 spins slower, BUT it also runs a lot longer to fill the tank. AS Steve explained to me, they did tests on the pumps, and when you are building 175psi, the pumps/motors last longer when ran faster, they oil better and run for less time...

I know we all like the idea of the slow spinning pump, the compressor I am building now is going to be around 1000 rpm, and to get to that rpm I did a little testing, I ran the pumps at 675-700, 850ish, and 1000 (I know how they sound at 1500 since I have some 7.5's sitting here) and the db meter showed within less than a single DB at 3 feet, so its not a huge issue for me.. NOW granted that was with all the same pumps making different cfm's...

If we took a pump twice as large and spun it half the rpms, I imagine the sound will be a bigger difference...
I guess my point is, if all you can afford is a 7.5hp pump, then spin it fast enough to make the 7.5hp cfm, if you can afford a 15hp pump and spin it slow with a 7.5hp then that is an awesome option.... AND keep in mind, the units were are talking about WILL outlast most of our hobbies and our kids hobbies, the NEW oil available is making these things never wear out, even the valves dont get dirty any more, like with the old non detergent dino oil...

I stick to the 7.5hp IR being the best buy at $1750 from zoro with a coupon shipped with no tax...

Do your homework, 2nd hand definitely has serious savings, but new gives peace of mind.

Whichever route you take, give a serious look at this BandPak
http://www.bendpak.com/compressors/air-compressors/ls580v-501.aspx

Baldor motor, great engineering & great specs, this would last you, and your kids and more.

Limited authorized dealer network, so you will not find great price differences. The "580/501" model on the link is in the $1950 range. If BendPak has a deal, then all the dealers should have it. Otherwise if you happen to have a dealer locally, you can ask them for some kind of deal. I think their invoices need to show they do not undercut their fellow dealers but can certainly add some goodies on the side.

Good luck.

 

[Finky198]

^^^ we run the newer 2475N7.5 and its far from loud

Taiwan pump on them Bend paks, although they do use a nice hearty baldor with the built in fan and a good starter, and nice tank, the pump is from taiwan, kind of ruins it for me...

According to BendPak's site, tanks are by Manchester, and they produce their tanks in NA or Australia. Even if it is Taiwan, as long as the tank is made by a company that specializes in quality tanks versus a China Fab spitting out as many as they can make; I'll take the former.

I find the BendPak has top quality components everywhere. Last year I came within a biscuit of getting the 5hp and backed off on the purchase as my compressor needs are slowing diminishing. I will revisit a new compressor purchase in 2016 and if I go ahead, the BendPak is easily leading the pack for my choice.

My 2 cents

EDIT; I misred, I thought you were talking about the tank, now see it is the pump.

Manchester makes about all the tanks on compressors sold in the US...

I agree, you buy what makes sense to you, I looked into the bend paks and the pumps should last a long time, just for the money you can get a bit more, and the pumps, not the tanks are what I was saying was made in taiwan... To me the pump is the important part of the unit, YOU WANT A PROVEN GOOD PUMP...

What I really didnt like about the bend paks was their baldor motor is not available with out ordering it through them (at the time I looked into them, not sure if its that way still), and they are saying its a 20amp motor making 23cfm, which judging by what others that own it say, it takes that pump almost 9 minutes to fill the 80ga tank, so that is more like 14-15 cfm, which is about right for a 19 amp motor...

5hp pumps should fill an 80 gal tank from 0-175 in just over 7 minutes, my brand new 2475's with a baldor l1430t's (also a low amp 5hp) filled the 80 to 175 in 7 min 2 seconds, 4 times in a row within 2 seconds!!! So that puts them just under 18cfm which is where I would want to see a higher end 5hp setup..

Just some stuff to think about...

Ok, i had pretty much settled on buying a saylor beall (made in michigan, like me!) 5 hp 80 gallon. Then looking at CL tools list, a guy posts this:

http://detroit.craigslist.org/wyn/tls/5381326871.html

Name brand, barely used, single phase, rotary-screw MONSTER! He is somewhat overpriced (new appears to be ~$5300), but how many people are in the market for a used single phase $5000 compressor? I expect it can be picked up for somewhat less than what he is aking for it.

Thoughts?

i would go for it if you can get it for say 3000$ or less. otherwise you wont gain much usefulness out of it over a regular compressor as most people dont need the full use of the cfm they put out. and these systems are always running and drawing more power.

my good friend got one from CAS, paid 10k for it. im not all that impressed by it. has to be serviced alot more then i would want.

 

[redmondjp]

Rolair is American made in Hustisford, WI and very reliable. Check them out.

American assembled, yes. Their pumps are made in Italy and distributed in this country by ABAC/American IMC. Same pumps as used by Belaire and many other compressor makers.

 

[md21722]

Some good information in this thread. One thing that always threw me was the high RPM of the IR2475 pumps. If you look at competition some 7.5HP are running 610-990 RPM versus 1500 RPM for the 2475. Glad to hear the oil looks good.

 

[unashamedlaborer]

If you can't afford a pressure lunricated Quincy which is the end all be all of recip compressors get a champion or Curtis. In that order. Avoid the IR at all cost. Screams like a banshee and is a total POS today. The older grey ones were much better. Current production units have one piece rods with no bearing inserts.

 

[jonjon1]

You can buy the 7.5hp Inger soll rand rotary on the 120 ga tank BRAND NEW SHIPPED from zoro with the 20% off coupon for $4100....

If you wait for the 25% its even less...

 

[edl]

Have an SB VT-735-80 - they are still producing old american iron new - it is a work of art and the smoothest compressor - old school and in your budget - you can't go wrong...extremely happy after 5 years or so

What do you think about the reports of IR's blowing head gaskets? and motors failing just out of warranty? I can partially attribute the motors to possibly undersized wiring for conditions.

Thanks for the write up Jon Jon. I will definately be looking at this route and being the 20% won't be until May is even better for me because that is probably about the time I'm going to upgrade. I Don't know if I need an air compressor that is 24 CFM but it is nice to know that I will have it if I need it. I deal with a Professional Craftsman right now putting out like 8 cfm at 90 right now. It is over 10 years old and going strong. I have looked at the Ingersoll Rand ones at tractor supply a couple times now and I just can't seem to get any questions answered from people that know less then me.

I agree with this, I have a love for compressors and take note of what every shop has and how they sound and tend to ask users opinions. I chose Quincy for my first, then I bought another Quincy cause having one wasn't enough. The sound of it starting up fully unloaded until it sees oil pressure is music to any gear heads ears!

 

[Todd.Brock]

I bought my first Champion 5hp 80 gallon from a guy whose shop bought s 7.5 hp IR. They regret getting it and taking the Champion out of service. I originally had a TS5N5 IR and it worked, but it was loud. Got the champion with a 3450 rpm motor. So much quieter, but nothing compared to a 1750 rpm motor and a slow churn pump.


That rotary looks awesome and they are so damn quiet, but if money was no object- it would be Saylor Beall for me.

 

[jonjon1]

jonjon1,

What do you think about the reports of IR's blowing head gaskets? and motors failing just out of warranty? I can partially attribute the motors to possibly undersized wiring for conditions.

-md21722

I think I mentioned the head gasket issue, that was 1 model, of their lowest end pump, the inline ss5 pump, it came on a $900 5hp package unit, and they have since fixed the issue, and I was told they will even still fix the issue if they break out of warranty, which is nice...

As for the motors, they are using WEG (pronounced VEG for some reason, lol) motors, and in my experience the company makes really good stuff, I have some of the weg motors that are way past warranty and still working fine, and know many people with them.

I think the motors are the soft spot of any compressor, their are 2 items you have to look at- 1 wiring, I know the BULK of home compressors are wired incorrectly, not enough wire there, NEVER checked with an amp meter to make sure they are setup properly, and installed against a wall with no air flow...

I can tell you first hand that 7.5hp weg motor that comes with the 2475-n75 is a nice motor, fast runs cool, makes good power fast, and has lasted people I know and myself a long time.

Another note on motors, google search how many people complain about baldor, lol... There are a lot and others say its the best e motor on the market??? I don't know, I know I wire them with sufficient gauge wire on the shortest runs I can make, I make sure they have adequate air flow, I keep them clean, lubed, and I check the startup amps when ever I adjust the belt and change the oil. (to tight of a belt will cook a motor just as fast as small wire), and sometimes from the factory a fan or compressors belt will be too tight...

So to recap, motors seem good to me, WEG is a big company and they are selling IR a robust well built motor..
The T30 pumps have had no gasket issues that I have heard of or seen on my units.

I can not think of a better bang for our buck than the IR 7.5hp 2475 80 ga unit, the amount of cfm, the quiet, quality, and reliability is all on par with more expensive units. DONT get too caught up on low rpm, as it was explained to me splash lubed pumps last longer spinning faster than slower, they make more air, the run for less time, and whether they are quieter or not I cant say, like I said I have some running fast and some running slow, the 7.5hp 2475 is about the quietest compressor making that much air I ever heard!!!! PLUS its an easier to get used to noise, not a chug chug chug chug, like my slow compressors, more of a constant buzz and then off, where my slower compressors chug chug chug for ever and then shut off...


PLUS dont forget the PARTS support, and IR is NOT GOING ANYWHERE, they are buying more companies for billions of dollars lol, you can get t30 complete rebuild kits for a couple hundred bucks..

AND if you are using the compressor for a hobby garage that may get ran 10 hours a week, pretty much any compressor is going to last you a life time...

That rotary looks awesome and they are so damn quiet, but if money was no object- it would be Saylor Beall for me.

BUT they werent selling you the IR were they, I would tell you "eh, I bought a new compressor but this one is better" too if I was trying to sell it to you, lol. jk

The ts5n5 is the lowest end compressor IR sells, I don't like it at all, I think you can do better for $1000, I would rather have a V compressor than an inline. I agree, them are loud, and not great units. BUT the T30 pumps are a completely different animal, they are a good design that has been around a LONG time...

May is the 25% off, its may 19th, I have the code in the calendar if you want it...

Yes please. I will write it down and put a note in my phone!

The thoughts on pump RPM are interesting. Any data on how much extra water may be introduced into the system by turning the pump fast? What are the head temperatures and discharge of the IR 2475 after 20-30 minutes of running?

I am not sure, but I can tell you this, the head temps on the 2475 are cooler than my quincy 5hp inline (splash lubed), and that has an aluminum head, which I would think would be cooler running.

Both compressors work awesome, I have no complaints, but the IR is cooler running, I use synfilm oil in all of my compressors...

When I finish my 5hp lower rpm duplex 2475 I will check the temp and I will also check the temp on the high rpm 7.5hp... I would imagine the 7.5 is going to be hotter because its making a lot more air out of the same pump. The real comparison would be to compare a 7.5hp 2475 and a 7.5hp 2545, spinning one slow and oe fast so they both make the same cfm, and see which runs cooler...

I'll bet the 2545 runs cooler, BUT it will aslo cost you twice as much, that pump is $2200 vs $1100 for the 2475, also weighs 100lbs more... A 2475 is around 200lbs dry with no fittings, the 2545 t30 is over 300lbs....

Most of the issue is the limits of our residential/hobby garages,
ONe of which is the largest single phase motors are 10hp, so a 10hp compressor will get you about 35cfm, since most houses dont have 3 phase power available...

SO 35cfm, sounds like a lot until you start sand blasting and have someone running another tool at the same time..

Now I figured I need about 35 to do what I want with out waiting on air.. BUT I DO NOT want to start a 10hp motor everytime I need air, so I am building a dual 5hp duplex, I will run on a single 5hp until I need more, this solves a bunch of problems for me,
1- the load starting a 10hp motor would be a lot all at once for my garage panel, 2- 10hp motors are expensive to replace, lol, 3- noise, 4- energy, 5- short cycling, 6- cost, 7- even if one goes down I always have a back up, and I am sure I can think of a few more, lol...

If I were going for a single compressor it would be 7.5hp, its a nice medium in the road, after that 2-5's... If you need a lot of air 2-7.5's....
