Help with 1967 Ingersoll Rand 223 30T Compressor

I recently acquired a 1967 223 30 horizontal compressor which has two pumps, two 1 hp 3 ph motors. the pumps turn freely but need new gaskets. there is some type of filter/separator/dryer??? which seems to have been interconnected on both pumps??? I am not able to locate a manual, any ideas or suggestions?

    In the process of replacing the 3ph motors and getting everything cleaned and re connected. The pumps work well, just need to figure out how to connect the multiple steel 1/4" tubes which come out of either a dryer or separator of some sort.

  • ellisonsc60 Jun 23, 2009

    I believe that it is a duplex with two pumps, two motors etc... One is set to shut off @ 90 psi and the other at 95 psi, all I can figure out is that one works as a primary and the other is a back up which turns on if the first can't deliver enough air??? My main concern is to connect the lines coming out of the separators properly. When the unit was removed the lines were just clipped and therefore I have nothing to refer to. I really do appreciate your time and assistance, by the way. I have removed the top of one of the pumps and it is clean inside, the piston rotates freely and creates good pressure on the upstroke and sucktion on the down stroke. I don't know much about compressors but this one is built very well, everything is heavy duty.

  • ellisonsc60 Jun 24, 2009

    Here is an image which may help. The small lines coming out of the separators are 1/4 and the large one is 3/8. There is also a 1/4 inch connection in the bottom of the tank.

  • ellisonsc60 Jun 24, 2009

    In the picture below I have two question marks, yellow and blue. The 3/8 (yellow ?) is the inlet, I hate to sound ignorant, but where does this line go to? The tank?

    Second line 1/4 (blue ?) scavenger where does that line go to? Do the 1/4 inch go to the 1/4 output at bottom?

  • ellisonsc60 Jun 26, 2009

    I believe that we are closer than ever. I am waiting for the gaskets and have obtained a single phase motor... still looking for a second one. I have removed the pumps and motors from the tank assembly and my son wire brushed and painted one pump and we plan to do the other one today. A friend down the road is going to sand blast the tank assembly and paint it with some left over automotive paint (unknown color) the I plan to get it assembled and have at least one pump running with the motor I have. I located a picture of a compressor that has a similar layout which I am attaching with another question for you. What is the horizontal pipe (appears to be a 2") that runs the length of the compressor? Mine has the brackets but no pipe.

  • ellisonsc60 Jun 27, 2009

    Sir, rest assured that a picture will follow when completed and I will send some progress pictures as well. Here's the first pump after my 15 year old helped wire brush and paint it (University of Tennessee, Knoxville colors) The other pump is getting a Duke University paint Job (his team) and the tank is yet TBD but one daughter is a UNC Tarheel and the other a NC State Wolf pack fan. So the paint job will definately be crazy. Camera battery is dead so I will send the picture in a bit.

  • ellisonsc60 Aug 25, 2009

    I have it running, a little soapy water revieled a few very minor leaks is a few of the fittings which I plan to resolve with some pipe thread putty. Have pics but can't remember how to post them.

    well it is a separator keeps the oil out of your air lines inlet would be on the side at a angle to create centifigal force for removing oil from air then the separator has its turn at removing the oil and your out put will be on top with a minimum pressure valve now there should be a smaller out put on top that goes back to the inlet on the air end that is your scavenger valve it sucks up any oil that gets past the separator the two pumps thing is strange though are they on a lead lag circut or do they work in tandem any way you look at it they should go to the same inlet on the side

  • alex MACHELL Jun 23, 2009

    how many lines come out of the top and how many go in the side and if you could tell me the sizes of the lines and there orientation example 1/4" out of top 3/8" in the side i should be able to tell you what is what also see if you can find a patent # and google that # goggle has a site just for patent #s that may provide you with a exploded view print

  • alex MACHELL Jun 24, 2009

    well the 3/8 " is your inlet and the 1/4 inch on top is the scavenger to **** up any oil that has gotten through your crank case at the bottom produces a vacum tha pulls out of the seperator and off the head so your bottom lines are out put and water drain i do not know which is what get up and running and trial and error just keep all lines to the crank nice and tight when you do have it up and going after a few hours when it has run nice and hot you need to go back over all the bolts retighten every thing just like a head on a car motor i would email the manufacturer also see if they can help i have found help that way before and look for any patent # and google patent search the # it may have some exploded view prints good luck

  • alex MACHELL Jun 24, 2009

    i think both yellows are output one may went to a machine the red is auto drain for water and the blue is the scavenger the crank case creates vacum and pulls of any oil that got into the head this what it looks like to me the red is not attched to the crank case right that is the way it looks to me i would use bottom right for air output and bottom left as a manual drain put a brass valve on it the first time you fire it up open all lines except the ones connected to the head and slowly close lines as it builds pressure and make sure you have a good pop off valve in case you build to much pressure

  • alex MACHELL Jun 26, 2009

    how goes your compressor did we get your problem solved

  • alex MACHELL Jun 26, 2009

    that looks like the air output to me that is a unusual comp. design but it looks like it may tie in to the out put on the other pump and the larger pipe may be acting as a dirt leg because it has a drain valve on the bottom of but dirt legs are usually run off a tee with a cap on it they are meant to trap dirt and water so it does not end up in your tool this is a big concern for painters i would like to see a pic. of the end result of your labor if you dont mind

Hi,I got a Ingersoll Rand type 30 model 234 compressor.It looks good but it has no motor.I'm thinking like 120v,3horses?,but not sure about rpm.any help would be nice.thanks

According to the information you provided your looking at a 10 HP motor at three phase. Do you have three phase at your location? If not I would look into getting a single phase compressor. If you do want to get it going I would notify your local IR dealer so they can get you the right Model number, RPM, Pulley and Motor Frame Size to match your unit.

Please read below....Jim...if this helped you please send me a positive response...Thanks!

You can build or buy a single to three phase converter....

If you want to buy then just do a search and many will come up...

You size them by amp. draw... the amp. draw will be listed on the motor nameplate...

Motor pulley for an old Ingersoll Rand type 30 compressor

Here is a link to Ingersoll-Rand (compressed air division) where you can find a local distributor. I think a call to a parts tech might provide the original motor sheave outside diameter and belt size (I'm suspecting "A" or "B" size).

With that info, here is a link to a good industrial source for your new motor sheave (McMaster-Carr):

Their prices aren't so bad.
You may also have a local industrial sales in your area.
I hope this helps you... Nice compressor!
