This was a compressor of my dad’s and I would like to find a rebuild kit for it. It is on a NAPA brand compressor I have pictures of model numbers Etc but there are very few markings on the compressor itself. Thank you in advance for any help anyone can provide.
Looking to find ID on this compressor pump… 5hp Baldor turning it (probably not original), no markings or tags on pump itself but attached is a picture of the plate on the tank. Was government surplus given to me for my farm. Great compressor but needs valves done.
4 cylinder compressor that came out of a grain elevator. It blew out 2 cylinders and I cant figure out what brand it is to try and find parts. Sorry for the double post
Used air compressor. Think IR. Help.
Trying to identify an older air compressor. It has a Melben tank with four legs. A 5hp Gould 230 volt single phase ac motor with start & run capacitors. Twin cylinder pump (Similar to a CH VTseries) with “C311A” cast into the side. A furnas 125psi pressure switch. It’s been painted at one point but the paint underneath appears green in color and the sticker is yellow. I cannot find any other identifying information. Thank you in advance.
Can anyone help me find a date for this? U.S. AIR COMPRESSOR Co.
Looks like it has something to do with grease as well..
I’m clueless… looking to sell it but don’t know how to list it without any info…
I need help with identifying this compressor from Melben.
Hello! Truly obscure Canadian compressor needs ID.
Who the heck is Milro Lyn? Can parts be had?
Was given this a few days ago. The person I got it from says the motor runs and the compressor works. I don’t have a clue what it is, maybe some one else does and what it might be worth if anything.
Thanks for any help.
Can anyone identify this compressor?
I know it’s a FIAC, but I can’t identify the pump. I’ve been told it’s an AB800 pump but am unable to confirm this or find any information on it.
I need a top end gasket kit and air filter assembly.
What kind of compressor is this and what is it worth
Looking for any information on this compressor.
I was given almost all the parts to build an air compressor but i don’t know much about them, just what i’ve been finding online already. I’m trying to identify the pump so i can get everything set up for it. The heads have ES-3-D stamped on each of them, the left head has 1201 on it while the right head has 13 on it. If my math is correct the pump is currently running at about 850 rpm but it is taking a really long time to build up pressure. I know part of this is due to the… Read more »
Need to know what this is or how much it’s worth?
Looking for hp and age info on this old cw1 champion air compressor pump. I know its either 2 or 3 hp pump…It’s powered by a 1977 8hp b&s and dont know if its an overkill for a 2 or 3 hp pump. Tank tag is hard to read but know that its an old national tank …Was it sold as a package or put together? Grainger maybe?
Looking for any information about this air compressor that I acquired. Manufacturer/model, are parts available for it. Is it worth restoring to use, or best just to sell or junk if it isn’t worth anything?
Thanks
Acquired this air compressor with my house and I am looking for any information on it. Can’t seem to find anything on the internet about the pump. Any help would be appreciated, Thank you
Picked this up at an auction. Was used in auto repair shop.20hp 220v 3 phase motor
I bought this compressor the other day and would like to know more information about it. I google American Air and it gives me all that are made here in America except for this brand
Hey guys I’m looking for information on this old air compressor that I am looking at getting to replace or add to my current pump that is too small.
The tank was replaced in 2008 and it is run by a 5hp 3phase century motor.
I’d like to rebuild this old pump for my dad. I don’t know much about it. He had it in his old slaughter house to pump coolant through the freezer coils. There does not seem to be any markings on it.
I’m trying to identify this blue compressor pump. It has no labels of any kind on the pump, but does have the number 151254 stamped on top of the body of the pump. This pump has been relocated to the current tank. A paper label was attached to the original tank stating Model 60H5S and S/N 002573 and 1 stage. No name on the paper label. The hoses are not original – it previously had copper tubing. It was repainted from a lighter shade of blue. The fittings have Made In Brazil stamped on them, so the pump may have… Read more »
I am wondering where I can find parts for this air compressor pump. It is, according to the front of the motor, a Smith model 28A50-12 with serial 28- . I have also found a few other numbers of 1103, 1104, 1105 (parts numbers?) under a few layers of paint on the top half of the motor. Any help with this motor would be great especially if a schematic of the whole thing is anywhere to be found. Thanks in advance. Reuben in Minnesota
Hello, can anyone help me identify this compressor? I cant find and info on the tI need a new check valve.
We’ve got an old Sears with probably a C-H pump with real valves over at

Roger, or anybody, can you take a look, please?
Thanks.
Trying to identify this compressor
Plate on tank says Buckeye Boilers and I’d dated 1986
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…….
