Identifying An Older Air Compressor

A local machine shop replaced this pump last week because of air leaking back through after it shut down. Seems like an easy fix and I like tinkering with old machines, problem is any identification tag is missing. All I know is that is a ten horse motor and the tank has been replaced in the last decade. I have found that a Worthington type c looks similar but not the same. If I can’t get parts it would be hard to spend much money on it. So if anyone knows the brand or even model that would be a… Read more »

I have this old compressor. The compressor unit is marked CBS and Made in England.
It’s running very slowly and i’m not sure if it’s the motor that needs attention or that the compressor rotating resistance is too high.
I’ve stripped the compressor to find a low quantity of what I think is very thick oil, but all the bearing surfaces look very nice.
I’d like to find some technical details, specifically what oil and what quantity is required.
I’ll add some photos of the stripped compressor later.

Trying to figure out this old-ish inline 2 cylinder. Need to figure out proper motor speed and pulley size anyway. Cannot find a brand but just those letter F-C and KC in different places, then some numbers both stamped and cast. Any help or info appreciated.

Thanks,
Dave

I picked up this compressor last week to replace my old one. If you could help me identify it so I can find the missing parts.

So I was very fortunate today to finally have the opportunity to purchase an additional air tank to increase my current air volume. The previous owner had passed away so his wife didn’t know hardly anything about it aside from saying it was 60gallons and he never really got to use it. My problem is that I have NO CLUE what brand or model or anything at all about the tank itself. I am not concerned with the motor and pump at all. I simply do not know the maximum rated pressure of the tank itself. There is no tag,… Read more »

Im pretty sure my father brought this home on a tank 25 years ago or so. He used it for years and the tank failed. He has since passed away and i have inherited his lovely unidentifiable stuff that my step mom didn’t sell. Seen a couple pictures online but holds no description. I cannot find any markings, serial numbers, or number plates. I have no intention of using it because i have a newer compressor. I want to sell it but would like to be 100 percent sure of what it is before i price it. Thanks in advance!

Hello, I’m trying to identify this compressor pump, it doesn’t have any markings that can be found to tell what brand/ model it is, but I think the fins that sweep around the pulley should be pretty recognizable. I was told that it was taken from a 15 hp machine and weighs about 400 lbs. Any help is appreciated!

Here is an old Western-Electric compressor from the phone company. It has been in the family since the 1970’s, and company must have thrown it out around then, so I am guessing 1960’s on age, but not sure. It is massively heavy. 2 cylinder. There is multiple ports and exists on the air lines, and I am not sure what each does. Out of the head two small lines go to a switch. Big line (about 3/8ths) goes to get cooled by the two fans and the copper line has fins on it and the copper line coils a few… Read more »

Bought this compressor the other day. It is working, but needs some TLC. No markings on it. Can anyone I.D. the make or at least the compressor?

Help! Well, lets try this again. Posted last week and somehow a picture(s) of another kind of AC got mixed with my post. Need help identifying the yellow air compressor in the accompanying photos. It’s a beast of a compressor motor driven by a Wisconsin VE4i 4 cycle gasoline motor. Only i.d. marks i can find on the compressor motor are H5864(?) stamped on the underside of the crankshaft opposite PTO and 1112 stamped at the top of the compression cylinder on the same side of the engine, If you’re not viewing a yellow air compressor on wheels, then same… Read more »

Can anyone help me identify this compressor ?

Looking for a parts manual so i can rebuild this compressor. Any help would be great! I would also like to know what the cfm rating is.

Found this in our barn! No stamp on pump that I can see

My Granddad has this old Compressor. Just wanting to get an estimate on how much it is worth.

Any info this compressor would be great ….age, is it worth restoring and using

That’s all the #’s on it what do I have here???

Gentlemen! Hoping for help identifying this 3 horse 220v unit I came upon with a roughly 60+ gallon tank from 1944…. Only the tank has a tag I’ve found, that appears to say “Presser Air Tank Co. 1944” Going to degrease Monday or so and maybe plug it in. But I see nothing else identifying. Thanks!

A healthy sized I so much appreciate any help with identification. Thanks so much! I have other pics, but maybe this is enough.

I picked this up a while back at an auction. Trying to id the compressor so I can figure out some specs. The only markings on the compressor itself are cast on the base and looks like X2-56. Can’t get a picture of that due to the angle. Motor running it is a 1/4hp. Works ok. Need to educate myself on it. Thanks.

HI,
have this compressor in my shop. looking for any information on when it was manufactured. thank you

Someone gave this compressor to our family years ago and we’ve just used it as decoration around the shop. We recently have been clearing out things to make room. We have had trouble identifying this pumps year, use/application and value even though we know it’s make and model. We were wondering if anyone has an idea of the background and year of this pump.

Never been able to find information on this Copeland compressor, 2 cylinders, no oil

Any ideas what type of compressor this is? Need to try to get parts. Only marking is on the cylinder block EM 1511/4935. Thanks.

bought at garage sale no markings at all…….no file marks either….anyone recognize it…….

My buddy pulled this old gal out of his garage but I can’t find any info on it regarding capacity, etc. I’ve searched the model number everywhere and still can’t seem to get anywhere. Any info would be great as he would like to sell it (depending on how much it’s actually worth). It’s pictured in the bed of a 2017 Canyon to better identify the overall size.

Thanks in advance!

Trying to id this old compressor think it is from 40’s have several of them this is the smallest any info greatly appreciated my google fu is pretty good but no luck so any info greatly appreciated.

I could use some help identifying this older compressor. I believe it’s a eagle/woods PV02A however the only marking on it is on the cylinder head “52122” from that I was able to narrow it down a bit. There is also a PV02A-HP model which I think just puts out a few more CFM. There is a PV01A model as well which looks very similar. It needs a little bit of TLC and I hate ordering parts twice so any help would be appreciated.

I was just given this old 2 cylinder air compressor pump and there are no identifying marks on it. As you can see from the pictures the shaft is exposed on either side. I am assuming one side is for a fan and the other the pulley. The cylinders look to be about 2 inches. 1.) Any ideas on the manufacturer? 2.) How to tell what size electric motor to run with it to get the best performance out of it? 3.) The dreaded CFM question. I can use a rotometer from work to give me a close ballpark, but… Read more »

need help identifying this compressor i just got a hold of. specs, diagrams and part availability. its a buckeye compressor. model v20-6c serial 6266. this is a serious unit. ive never seen a pulley with 3 grooves nor have i seen a pump with 2 low pressure transfer tubes. this thing weighs a ton. it was mounted on what seems to be a 80 gallon refrigeration tank. ive never seen anything like this, although i am not very old. any help would be greatly appreciated

1948 Westinghouse Air Co Compressor Help. I am happy I found this page! I just got this as the seller thought it was a 1988, but its a 1948. I cannot find anything on an old vertical compressor and I would like to rebuild her.. I would like to know the following:

1) Tank Size 30ish x 21ish
2) Think its a 1 HP, would like to confirm
3) What oil do I need to use to change old Green oil
4) What is the model and where can I find parts?

Any help is greatly appreciated!

Can anyone identify these old air compressor motors, one has been cut away to show the inner workings but still turns, for a teaching aid I’m assuming, would be interested to find out as much as I can about these items. The cut away I’m hoping to motorise so the motor turns very slowly just for a really cool talking piece.

Can you help identify this compressor? Looking to get an idea of value.

Can anyone tell me when this was made?

Does anybody know where I can find a replacement valve cover for this Kellogg American 311TV. I broke the high pressure side cover trying to get it off. It looks like a square head flanged pipe plug.

Was wondering if anyone could id this old pump that was left in my shop when I bought it has no markings or plates on it?

I bought this compressor in 1983 she has been great, just not putting out like the old days. I would like to rebuild it if I can find parts. It was purchased in Seattle from Stoner-Forsyth the only numbers I can find on it is 1398 casting number and the data on the casting, V230 9 23 82 17157A
Volts? Date Serial #?
Any help would be great.

Hello folks. I have been handed down an old compressor pump of which I’ve rewired. It has tremendous sentimental value. It appears it now functions as should, although I have yet to do a high pressure test. I have no tank for it. As for identification, I have scoured the internet reading threads, digging for information and endless image searches to no avail. I aswell have tried searching all the number stamps on the pump and even tried seeing if I could correlate the pump to any compressor models also to no fruition which brings me hear to you fine… Read more »

Need help to I’d manufacture of this compressor. 10hp 3 phase motor. Got a partial on company that sold and serviced but they no longer at
phone number

Hi, would someone be able to identify the compressor in these pictures. It has Curtis Pneumatic on it, but I’ve been told its a Quincy compressor. Also wondering if this would be re-buildable, as it’s getting a little tired and slow pumping. Where would I be able to get parts for it?

Just recently received a free tank that was an old compressor. My air compressor blew up and I’m gonna build this one instead. But was wondering what size tank it is and what everything means on the tag before I start the project.. any help?

I’m trying to identify the make of this compressor which I recently acquired. I’ve recently pulled it down and reconditioned as best as able. Can someone help identify – Thanks!

Ed

Hello gents, I’m hitting dead ends trying to round up parts for the Chicago Pneumatic air compressor in the pic. I dime you guys are experts! If you have ideas I’d gladly listen. Thanks for any help.

(CP can refer to a different make of air compressor too, so I added the whole name. Nice unit. What parts are you looking for? – Not quite the expert you may think!! – Moderator)

any ideal what this is?

Any ideas on this one? Id love to know what it all is, pricing, gallons, psi, etc. for the whole lot. The tank measures about 49″ around and about 42″ tall. There are numbers and possibly letters on the tank I can’t read (shown). One tag on the compressor says devilbis model 220 (shown). There’s also a ge motor tag shown. Hoses included. From what I can tell, it works, but I don’t know a lot about compressors. Thanks for your help!

Any ideas on this twin cylinder pump? Cheers

I wonder if anyone can shed any light on to this old compressor pump. It was given to me a while back and I just dug it out again today. I haven’t run it much but it goes to at least 75psi and is nice an quiet. There’s only a 1/2HP 1725 RPM motor driving it right now. Can’t see any casting marks apart from the number on the side which could be R5800 or R8800. It looks like a twin cylinder and has what seems like pressure adjustment knobs under those brass caps in the head and on the… Read more »

Need information on this compressor

Trying to identify the make and model of this, please help.

I just “inherited” this air compressor. It says Snap-on but I can’t find a model number. I need to know how to change the oil and what replacement parts I need. My googling so far has been unsuccessful.

Hi, looking for basic maintenance info on a Brunner model 102. I just got it, but nothing is broken AFAIK. Things like: 30ND oil is OK? How much oil? Parts that should be disassembled and cleaned? Etc. Thanks!

I am looking to rebuild the pump on this old John Wood compressor but cant figure out what it is. Can anyone point me in the right direction.
