For years it was assumed that Ingersoll Rand air compressors were built for the industrial market. And they certainly were. We are not sure when IR made the move into, shall we say, smaller, more consumer oriented compressors, but they are in this market too, with a vengeance.
On this page we would like to focus on the smaller, reciprocating Ingersoll Rand air compressors. Yet, with the comment section, we invite questions from folks using any of their models.
If you are an IR air compressor user, and you see a question or comment that you can help out with, leave your thoughts as a comment there, if you would. Of course, only comments and questions about Ingersoll Rand air compressors can be added to this page.
We are focusing on Ingersoll Rand air compressors, like the bad boy shown in this next photo. Sweet machine, hmmm?
Ingersoll Rand air compressors are available from industrial supply houses, yet nowadays are available from a string of retail sources like the Home Depot, Tractor Supply, Northern Tool and a host of on line suppliers.
We would like to think that their move to a more consumer oriented product did not mean that they cheapened the quality of their historically quality oriented and reliable compressors.
At least, when you buy an IR air compressor, you can talk to the manufacturer should you have a problem. In North America technical support for the Ingersoll Rand brand of compressors is available from:

50hp screw compressor. losing a gal of oil every 3rd day with no visible signs of a leak. Anyone have any idea what is causing this?? Low oil sends hi temp warning an shuts compressor off..
I have a Ingersoll Rand SS3R2-GM and yesterday I heard a loud pop and noticed the gauge cover had cracked and was blown off.
Fluid started coming out of the gauge.
Would this suggest a faulty gauge or pressure switch?
I don’t want to start replacing the gauge if something else is causing the failure.
Also, as the specific gauge model is pricey to me at $70, are the other IR gauges compatible? Thanks.
Tim, I uploaded a photo of the compressor in question, and moved the post to the Ingersoll Rand compressor page. Has the compressor been stopping at the normal cut out pressure before this with no problem? What was the pressure at which the gauge cover had cracked, and what “fluid” was coming out… oil, water? If the compressor is out of warranty, no need to use an OEM gauge if you find them too expensive.… Read more »
I’m looking for a water cooled after cooler for a horizontal T30 compressor from early 1960’s
I have a TS4N5 IR compress that won’t cut off at the set psi and is lifting the PSV, I bought a new pressure switch and switched them out however it’s still pressuring up until the PSV lifts. It may just be a faulty switch since I tried shutting it off on the switch and it didn’t stop running and I had to throw the breaker. Is this common? Could it be something not telling… Read more »
If the pressure in the tank is bypassing the cut off pressure setting on the switch, meaning that power is still flowing through the switch even though the pressure should have tripped it to off, and there is nothing blocking the tank pressure getting to the switch, then it’s almost certain that the switch is the problem. Please double check the pressure settings, and ensure that the supply side terminals and the motor / load… Read more »
I R 2 cylinder two stage 80 gallon reciprocating air compressor. Air pressure backing up into cylinder causing pump to lock up.. When I bleed the pressure from the holding tank pump spins.
That sounds a bit like the air isn’t getting from cylinder one into cylinder two, and that means a blockage of some sort if so. I would suspect the intake valve on cylinder two to be an issue if this were my compressor.
Then why with the compressor off holding tank empty i use an alternate air source to fill the tank and at about30psi.
I can no longer turn the pulley wheel on the pump by hand. Actually i cant turn it at all until i bleed the air back out of thetank
David, I’m not entirely sure what you mean by “compressor off holding tank empty”. If the compressor tank has a charge of air, then the air in the tank is pushing back against any more air entering from the pump cylinders. This may exert pressure on the pistons in the cylinders preventing them from moving until the load is removed. It sure sounds like an back-pressure caused lock up to me, and removing the air… Read more »
80gallon holding tank. No pressure in tank. I turn on air compressor it starts up fine. Pressure regulator set at150 psi when the gauge that reads tank pressure reaches about30 psi the pump locks up. Meaning that the pressure in the tank is putting back pressure on the pump not allowing it to spin.what could cause that
Got it. OK, the air comes from the first cylinder to the second, yes? If there is a block in the intake or pressure valve of the second cylinder, the pump will lock up. If the second cylinder valves are good, then the only other thing that might cause this symptom is a failed tank check valve which, when experiencing 30 PSI back pressure from the tank, refuses to open further, and stops the air… Read more »
I have a 80 gallon IR two cylinder two stage reciprocating air compressor. Pressure backs up into the cylinder and Lock’s up pump.when i bleed the pressure from the tank the pump is fine. I believe that the problem is the check valve but where is it.
(Post moved to the I.R. page – moderator)
Their 80 gallon compressor has a number of configurations for the 2 cylinder / 2 stage unit. Wish you’d included a model number, as I can’t do any real research without that, Dave.
Typically though, the tank check valve is part of the fitting where the air line from the 2nd stage enters the tank. Take a look and let us know, OK?
Thank you I will be removing the air line from cylinder into tank this afternoon.I will let you no how everything works out
I have an IR UP6-7.5 rotary screw compressor that will not restart automatically after the pressure has drop to the restart point. from empty I push manual start button and everything is ok till it hits 150 psi the it shuts down,like it should but you can run it dry and will never restart unless I hit the manual restart again.I have already replaced the pressure switch, and have tried operating in both the continues… Read more »
I want CMC service tool with license to communicate PC with BCM or OUI or ucm could you help me?
No, I sure can’t. I expect someone out there can, so happy to post this for you. Watch for replies. Good luck.
I have a 5 HP 60 gallon compressor (IR SS) that runs good in the fact that it starts and stops when it should but my problem is that it losses pressure at the tool right after the motor/pump shuts off. This lasts for about 5-8 seconds. This is no big deal when using grinders or similar tools but when using a paint gun or my plasma cutter it becomes an issue. Does anyone know… Read more »
I have an Ingersoll Rand 5 horse single stage 60 gallon compressor. I bought it new and it worked awesome. I could hold a blow gun wide open and it would still pump up and shut off. I use it in my pole barn and it doesn’t get used to all that much. After approximately 15 or 20 refills over the course of about a year-and-a-half, It just started running and running and running and… Read more »
That the regulator gauge displays 15 PSI over the tank gauge suggests to me that one of the two is not registering the correct pressure. Consider swapping them and see what happens to the display. If the disparity reverses, it’s time to replace the gauges. As to running and running and not building pressure, please see: //fix-my-compressor.com/compressor-will-not-build-pressure/ .
I have an ingersoll rand 7100e15v. It started out as tank pressure bleeding out of the unloader valve on the pressure switch. We have replaced pressure switch with a new one, that didn’t work. I contacted Ingersoll rand and they told me that the heads need to be rebuilt. So that was about a $500 kit with the same results. The problem is the pistons have no relief holes, there is no unloader piston in… Read more »
Also, I forgot to mention that this particular model does not have the optional centrifugal unloader components. I am attaching some photos.

I have an Ingersoll Rand T30. Recently it started kicking the breaker after running for about 5-10 seconds. I was testing it with the write up on this site when one of the capacitors blew. Was it a bad capacitor, or do I have a bad motor? Any suggestions?
Thanks,
Michael
Don’t know how testing a cap should cause the cap to blow. I would hope it was the cap. Easier and cheaper to replace that than a motor on your T-30.
I have an Ingersoll Rand compressor with 1 port p/switch, the compressor starts up and stops ok but won’t start again when the pressure drops. I have tested the continuity across the connections when the pressure drops and can see its made but compressor won’t start until I press start but again can someone help, thanks
Gareth, when the compressor reaches cut out and stops, can you determine if the unloader valve is working? Please let us know.
Hello all. I found this site via google, and it appears to be a wonderful site for information about old (and new) compressors. Thank you for that 🙂 I have recently aquired a very old Ingersoll Rand Type 30 253 with serial number 98724. Does anyone here have any information about this compressor pleaes? Would be very nice to know when it was made, amongst other things. Is synthetic oil, e.g. Ingersoll Rand XL-300, any… Read more »
Hi I have just started working on a 1946 type 30 model 242 I purchased earlier this year I think it is all original even the electric motor is a 3 hp British Thompson Huston repulsion which I have had overhauled can anyone tell me where to obtain spares in the UK as there is a part missing from the centre of the crankcase cover I do not know what this does so I suppose… Read more »
I have an Ingersoll Rand model SSR-XP7.5 rotary screw compressor which refuses to shut off at the high pressure point set. I’m suspicious of the two way solenoid as it seem to want to slip entirely out of its housing. I’m assuming it should remain in the housing rather than move up and down. When it slips all the way down the compressor runs but makes no air, when I manually push it up the… Read more »
On our Ingersoll Rand Air Compressor there is an Alarm condition Power Module Test 7 and mentioned on display. Any ideas why?
I have a IR 400 VHP with a cummins diesel, starts good the when I push the service air button ,it runs up builds 200 psi, but nothing out any of the ball valves, I drained the water off og the seperator and out of the air cooler still nothing, whats up? please
We are happy to post this for you in the Ingersoll Rand section, in the hopes that a visitor with experience with your compressor can comment. None of use use your model of compressor, so we hesitate to guess.
Hello, I own an IR 60 gallon C2340 compressor.. Recently it hasn’t been shutting off at times.. blows the PRV.. Even switching the switch on the compressor unit itself doesn’t work. I have to shut off breaker.. I believe that the contacts are burnt and sticking.. When the power is off I have to pull them back manually… Is there another possibility that I should look at?? Can you buy just the contacts or do… Read more »
Good questions, Brad. We think, too, that the pressure switch is at fault. The points may have just worn out, or there may be some arcing, indication, perhaps an electrical short of some kind in the power circuit. We are not seeing any parts supply or information on line about the C2340 IR compressor, so cannot comment on the source for parts.
So I have a two stage 1973 Ford Rotunda 3 phase 10 hp compressor manufactured by Ingersol Rand. Because it is 3 phase I have to power it with my 12kw 15 surge Onan 4 cyl diesel generator that’s probably a few years older than the compressor. I got the unloader working properly to remove head pressure on both heads. There is no tank check valve but the location of cylinder output pipe to tank… Read more »
I know that this picture doesn’t show what I am talking about. This is the sellers photo on Craigslist. I will try to take a pic tomorrow of the valve. You can see the tank fill pie and the head to head tube and tube down to unloader though… The relief I am talking about is on the manifold rear of right hand cylinder.
Can anybody help me? My Ingersoll Rand IR400 air compressor has a problem.
It seems every thing is ok but when I open the release valve there is no air. Does anybody have any solution?
Hello – what an awesome site! I have limited knowledge on electrical things, but here goes. I have an Ingersoll Rand 2475N5 compressor – 230V. It’s rated to 28 Amps, and we have it hard wired to a 40 amp breaker. I double checked the connections and the wires and connections seem good. It’s been running fine since I got it about 6 months ago. It just recently stopped working. When I turn it on,… Read more »
Thanks for your kind comment, Ryan. We have uploaded an image of what the internet says is your air compressor, to make it easier for folks to know what we are talking about. As to what is wrong, you need to do all the checks posted here: //fix-my-compressor.com/compressor-trips-the-breaker-on-restart/ . When done, add a comment with your findings if you still need help.
