brand new ir compressure and will not build any pressure they sent me 23191877 valve&gasket kit but no directions or specs for torque(spelling?)looked at book and there is 2 valves???????????wtf?

Al, it's odd, but I guess not unheard of, that a brand new air compressor won't build pressure.

I don't know anything about your air compressor from your post. If it's oil lubed, you would likely have had to add the oil when you got it home?

Compressors are, as you now know well, noisy. It is difficult to hear an air leak from a fitting or tank drain on a running compressor. Take pains, then, to check the tank drain is closed. On some new compressors they ask you to run the compressor for a period of time with the tank drain open as a compressor break in process. If yours asked that, did you close the drain?

Pull the air inlet filter and feel if there is suction when the compressor is running. There should be.

If you must tear it down, do so carefully both in terms of reassembly, or identifying the location on the compressor of the replacement parts you received.

Know, as again you have found out, that many mass-market, low cost compressors, have no North American support, and they truly are made to use and then throw away.

Good luck.

Bill

Ingersoll Rand blowing breakers

by Marty
(Raleigh,NC)

I have an Ingersoll Rand 80gal 230V, 5hp two stage reciprocating compressor. The Model # is 2340N5-V. When it turns on, it appears to be struggling to come up to speed, then it blows the breaker. I also see some sparks coming from the vents in the front of the motor. The compressor is less than 3 yrs old, but out of warranty. It also gets light duty, home use.

I checked the pump to see if it was load related, but the pump can be turned by hand with normal resistance. I hadn't disconnected the belt, so the motor turns easily as well.

I thought it might be the starting caps. On visual inspection, they have no bulging and appear in good shape.

I suspect this is motor related, maybe brushes. But with so few hours on it, this is an unusual failure.

Thoughts or suggestions???

Sparks coming out the front... hmmmm? It sure sounds like a motor problem to me. Flat spots on the brushes from sitting idle, maybe?

Good luck.

ir2340 compressor
by: Russ

Dont Know if this helps, I have this same compressor . When it is very cold out it will trip the breaker, My solution was to run heat tape on compressor head in winter,

Same issue
by: Bryan

Mine 80gl ingersol rand did the same thing and i have to replace my motor nearly 500$ i tried to use a tractor supply compressor motor lasted a week and wouldnt work after that all i did was auto body da work. i called ingersol rand and they said the company who made the original motors and them were in a fude over these motors and that they have a new company making there motors but lo and behold that the customers cant get a warrentyed new motor yet we are all having the same problem!

I got mine fixed. I bought a new motor for $295 and installed it. It worked well. The compressor is now back up!

Tripping breakers
by: Bob Coffin

I have and Ingersol Rand compressor model SS5L5. It was purchased in 9/06 for light home use. About 2 months ago I tripped the 30 amp breaker a couple times and upon resetting it and turning on the compressor, an spark shot from the shaft end. I took the motor to a moter shop and they told me that there is a hole in the winding which was probably due to a weak spot. I am now looking for a new motor. About $426 from the IR repair shop. Good luck.

RE:Ingersoll Rand Blowing Breakers
by: Marty

Thanks, I am thinking the same thing. The next step will be to remove the belt and see if the compressor still stalls. It is possible the pump is binding when it tries to get to speed. However, I would suspect it would show in the oil. I didn't see any metal in the oil.

As for idle time, the pump runs at least once/twice a day (small leak in the plumbing, plus air removed to drain the tank). But, it certainly is not being used to the frequency it was designed for.

IR COMPRESSOR SHUTS OFF WHEN IT GETS HOT

IR COMPRESSOR M# SSRUP630-150 AFTER RUNNING THE COMPRESSOR GETS HOT AND SHUTS DOWN AND WILL NOT START BACK UP UNTIL IT COOLS DOWN.

________________
Bill says...

What's getting hot on your compressor, I expect, is the motor. It has a thermal overload to shut it off if it reaches temperatures that are dangerous to it.

The motor is getting hot because it isn't getting enough voltage, it's wearing out, the run capacitor is failing, or there is a mechanical issue with the compressor that is overloading the motor. These are the usual culprits.

If the problem just started, is there anything else that's been added to the same electrical circuit that might be siphoning off voltage?

Cheers,

Bill

IR 575 v air compressor at home?

by Paul
(Oakville, Ontario, Canada)

Hi,
A friend of mine is giving me an IR 575v air compressor and I would like to know what I would have to do to use it at home. It's only 2 months old with an 80 gallon tank.
That's all I know at this stage. I hope that's enough.
Paul.

Paul, at the risk of being trite, you need to have a 575V power supply, unless you plan on changing the motor.

And, I suspect you will not be able to get a 575V feed via a home wiring system. Check with Ontario Hydro or your local electrician.

If you get the power to it so that it will run, I suggest you start reading the Plumbing pages for information on how to get it working, as far as your air supply goes.

Cheers, and good luck. Oh, and I've wandered the lake shore in Port Credit a number of times. Nice part of the world.

Cheers,

Bill

Not wihout some work and calculation
by: Anonymous

If you are using this at home, it will be far cheaper to source a single phase 220V motor, install it, and re-pulley the motor for the proper rpm and amperage draw. Having said that, the most you will be able to run is a 3~5hp motor, on a fair sized breaker, so be sure that the compressor on offer can be adequately powered by a motor this size. Large compressors are nice, but they are often too energy consuming to be used at home. Consider that you will have approximately 1/3 of the voltage to work with, your amp draw (all things being equal) will triple, and going from 3 phase to single phase makes that even worse. It might be possible, but you will probably have to slow down that pump so much it will produce very little air or pressure, and might seize up if it runs too slow.

575 volt question
by: Paul

I stopped at Oakville Hydro today and talked to an engineer and he told me to look for a Phase Converter. Will that work???
Sorry, I have no electrical background what so ever.

Paul.
