I am looking for a manual or schematics for an Ajax (Ingersoll Rand) air five horse gas air compressor manufactured in 1986 and I believe the model number is aj5620. Please HELP !!!!!!

Here we are using ingersoll Rand industrial air compressor. For the first time, it is having issues with cut in and cut off delay. Usually it cut in at 6.5bar and cut out at 8.2bar. Strangely, it is errantic in this sequence. Sometimes cutting in around 4.5bar and cut out 7.6 or even higher than the normal setpoint. I wish to know what could cause this variation and what should be done to return to it good operation?

Are we talking stationary or portable? Model?
Did you start seeing this over some time, or suddenly?

Hello, I bought an ingersol rand 4000 5hp 80 gallon 230v upright compressor the guy I bought it from had it outside and the identification stickers have faded and are no longer legible. It works just fine but the compressor leaks oil. I’m trying to identify it to get some replacement gaskets. There are no part numbers anywhere on it. Please help?

Even if you ID it, you probably won’t find gaskets.
Consider making your own.

Hello, I’m a new owner of a 2012 XAS 185 7D. I can’t find a user manual for it with the John Deere motor. I’m trying to find out if I need to add coolant as there is none in the resivior.

Hi I have a Ingersoll rand IRNB5K-8 H intellidrive failed can this be converted to a aftermarket VSD?

You mean just sub a different controller?
I suppose, but probably trickier to get right than it’s worth.
Or were you thinking something else?

The rest of the compressor is in good condition the motor is fine just the intellidrive unit which attaches to the mother is faulty had motor tested so would like to remove the intelli drive and fit a VSD or VFD after market system to the compressor as a new compressor will cost me almost 7 grand

Still, I’d just get the intelli drive fixed or replaced if I possible.
e-bay? I-R?

Good luck.

I-r intellidrive £3000+vat +labour can’t find one on eBay

Ouch. Is that the entire electric system, or what?
Anyway, let’s back up a bit.
What leads you to believe the ID is at fault? Have you verified all the contactors and the PSU are OK?
How did it quit? Or, when did you notice a/the problem?

Had a compressor guy in took it apart and there’s a smell of burning from within the intellidrive drive and burn marks can be seen on the grey resign that protects the pub inside the intellidrive. Motor taken to motor rewind company motor is fine PSU is giving all the correct voltage on the out puts. Was running, has smoke coming out, so I isolated power and the smoke stopped called the compressor guy out and he’s said it’s probable to be intellidrive before he even opened it up as he said he’s had a few of them. He said… Read more »

Well, that’s good and bad. Here’s hoping he can beat that £3k++ price by a long shot…
Let us know, would you?

Thanks and good luck.

2004 Ingersoll Rand XP375 screw compressor wont idle down when air is off?

Compressor starts and then idles for a few seconds before running up to 2200 rpm. Hit the switch and it builds air but wont idle down under 2200rpm. Open the air, runs up to 2400rpm. Close the air, back to 2200rpm.

I’ve replaced the 0-100psi transducer and one of the blowdown valves. Tried covering the intake on the compressor to see if the plunger is not sealing but it didn’t change anything. Anybody ever have any issues like this? Any help would be appreciated.


That sounds normal except the idle control is set too high. Unless you were thinking about something you didn’t write.
