Old school compressor help...(pics in here!)

[nickwrx]

Ok, the old man gave me his old man's compressor today! Never knew he had it or that it worked. Its a square D company compressor with a Dayton motor, but I am trying to figure out exactly what kind of CFM's this thing pushes and what I can run off it? There are no other labels other than the pics I have below. I traced the motor through granger.com and here is that link(http://www.grainger.com/Grainger/items/6K148). That is the newer version but still the same.

But I still am trying to figure out what kind of air this thing pushes. And please dont tell me just to hook something up and try, this is the reason I am asking. I want to buy air tools but dont want to waste my time or money if this thing cant run them.

Also, any suggestions on repair or maintenance for this bad boy? And yeah, tomorrow is degreasing day! It needs a good cleaning...

I think "Square D" is just the pressure switch manufacturer. If it has a Dayton motor, chances are it's a compressor that Grainger rebadged from some other manufacturer -- such as DeVilbiss

Nick I think its actually an ooooold champion compressor . Look on the tank there should be a metal plate that will have a model number on it . The plate on my tank is painted the same color as the tank which oddly enough is the same color as yours mine is a 75 gallon and the tank was produced in the 50's.

Wow, Hey Rick, do you really think its that old?! I mean, my grandfather could have gotten it from his dad, which my dad did mention he might have. So should I try googling "champion" compressor or what? I just want to see what this thing puts out. What's nice is it has on the side some general maintenance info but nothing about anything else. Kind of strange?

And what if granger rebadged it, then what? And how can I tell if this thing is safe to run?!

 

[rickairmedic]

Nick my tnk is out back in the dark and rain at the moment but I am pretty sure the tag I am talking about is on the side near the stickers on the tank itself. The model number and date of manufacture will be on that tag . I dont have the compete compressor by the time I got mine all I got was the tank but I used it for several years as a secondary tank on my system with no problems. You should be able to pull a couple plugs on the tank to check the inside . I will say that is most likely a better compressor than just about anything you could buy today.

Hello I believe I have a compressor just like that made by Johnson Service Company, it was a rescue from local junkyard poor little fella.
It says
Model 200 J20
Here are some pics,

 

[Jared]

its a fairly small pump i would guess about 5 cfm.

 

[rickairmedic]

The size of the pump is actually not easy to tell if that tank is the same size as mine it is about 4' long and 2' high by 2' wide and that doesnt count the leggs.


Rick

 

[DHS]

I agree with Jared, it is on the small side, but should be a quiet, durable pump, with a little patience will serve you well. As far as air tools it probably will not run them long. Still a very nice compressor.

 

[DHS]

If his pump is the same as mine from the mounting plate to the top of the head is only 10".

The picture made the tank look like 2 x2 to me, sorry.

 

[nickwrx]

hey guys, yeah the tank is about 2x2. Its not 4' long, def not that big.

I am going to clean it up and see if I can find any more info on it.

 

[rickairmedic]

Ok so its smaller than mine but its still the same color so I would bet it has the tag on the tank which will tell you how big the tank actually is and what year it was made .

its a fairly small pump i would guess about 5 cfm.

I would say that 5cfm is probably the max. The motor is stamped as 1hp, but 13.6amps seems high for a 1hp motor, so the hp rating might be underrated somewhat.
I typically guess that you can get somewhere around 3.5cfm per HP of the motor. This varies depending on the efficiency of the pump and other variables.

 

[Major Ramifications]

Definitely, Square D made the pressure switch, but that's it. What do the stickers on the TANK say? It looks like the motor has been replaced at some point. Dayton motors are sold by Grainger and are commonly bought as replacements. Also, it looks newer that the rest of the unit.
I wouldn't think that tiny single cylinder pump could give you much CFM, but it should be safe to run. It reminds me of my first compressor. It was very quiet and had a pleasant, chugging sound that my friends and I used to find humorous. Not much output, though.

 

[nickwrx]

yeah its VERY quiet! I just bought some light air tools to run and it ran some and I watched it drain a little bit. So some quick on and off action should be ok.

Oh and the bottom of the tank has 2 pinhole leaks. How should I go about fixing that? I figure some bondo or epoxy?

 

[3/8"indestro]

looks like [guessing here,based on the pictures] an old 120 Series Devilbiss pump,go to the the Devair site,they should have the manual/parts list.

 

[Charles (in GA)]

A one horse motor will only push about 5 or 6 CFM, possibly a slight bit more.

Buy the air tools, you will use them one way or another, if nothing else, it will give you reason to get a larger compressor someday. This one will fill tires, blow things off, even run an impact to bust loose a wheel, but not much more.

And considering this statement:

It could very likely push just a little bit more. Like a piece of metal through your head. No wonder this thing was removed from service.

IT'S DANGEROUS ! Get rid of it. I don't care how neat it is

 

[nickwrx]

So is it really bad if the tank leaks? I figured you could just put some bondo on there or something?

And is the whole thing scrap or could I keep the motor, etc?

 

[rickairmedic]

Nick if the tank has pin holes it is pretty rusty inside and probably not safe . Thats why I recomended pulling a couple plugs and having a look inside. I would say you could pull everything off the tank and look for another small tank on craigslist and assemble your parts back on the newer tank. I would look for a 30 gallon unit on craigslist that maybe pooped a motor or pump then you have a good tank to put your parts on.

Please listen to our "Boy Elroy"; he is providing you with good advice. The tank has been compromised by rust -- and no amount of "fixing" will change the fact that your tank has a permanent structural defect. It can burst and cause serious bodily injury.

Scrap the tank, keep everything else. You may run across a nice tank somewhere along the way.

 

[DHS]

You could put the pump, motor and pressure switch on a new tank. It is probably easier to just get a new one. I like old stuff, but once you use a new one you will quickly forget the old one.

 

[nickwrx]

Ok thanks guys. I knew I loved this website for good reason. There goes $300 when I thought I could save it! haha, maybe I can try and sell the motor and pump and trash the rest. Thanks everyone!
