Vintage compressor...

[Deleted]

Picked up two compressors this weekend... ones vintage the other a newer craftsman.

As far as I can find, seems the vintage one is a Kellogg. model 321.

at least 60's model, 2 stage.

The newer 321's are 2-3 hp. the older seem to be 5 hp.

going crazy looking for specs...

the tank has a plate, devilbiss spray painting system
motor-81211815
compressor A3228
spray gun capacity 4-a2k1e3

the head has model 321 and serial.
plus
6417445
12-23-5
on the cylinders.

17293 on the lower half plus a lager number I cant read...

Anyone able to help Identify?

I can post pics maybe...

Blows my mind that the tanks only rated for 80 psi though...

I figured out what I have, Its a Kellog 321. 7.4 cu per min / 175 psi.

The shaft was tweaked from tipping at some point, pretty good I might add.

Stuck it between two old and close pines, turned the pulley so high side was bottom and then used a Bottle Jack to bend it back.

Still a little wobble But pretty good.

One small problem is a crack in the bottom of the crankcase.

Hairline but leaking,I think I can braze it.

Breached a small hole in tank first airing, so I welded a decent size patch on and she hold 175 psi.

It will be nice to not have to wait for compressor to catch up.

I plan on running black pipe through the shop and Locate compressor on the lean to side of the pole barn.
Pipe off compressor run down to a black pipe T attached to 5 gallon propane tank with a drain welded on, off compressor, then pipe at a slight angle almost to rafters ,then change direction and again at slight angle, where it stops I plan on having 4 100lb propane tanks, which would be around 120 gallons, tanks would be upside down,so to drain any moister that makes it that far, and pided down to a tee at waist level, the straight leg down to another 5 lb tank with drain and the side leg would then be piped around shop and quick connects,water traps,and pressure regulators in different work areas.

At least you aren't doing it in PVC like was the craze a while back.

Just be careful what you do.

That black pipe will rust very well.

A better water trap would be smart.

The last place I worked full time had several water traps that we bled out every morning.

Sounds like you got it going on Downhome. I picked up one of them vintage compressors at a junkyard a couple years back. It was so vintage I couldn't tell what kind it was at all. Its got an electric motor on it and when I plugged it in ran okay. About halfway through airing up the tractor tire it cut off and went to just humming sound in the motor. I didn't know what exactly to do since I was in a bind at the moment, so I reached out and bumped the motor with a piece of firewood that happened to be within reach. That fixed it up and it went to running and pumping air again. Nowadays its always hung up like that when I plug it in so I've kept that piece of firewood handy, and the procedure is to plug it in and just give the motor a bump with the wood, and it stays running til I'm done. I think I'm going to have to get a motor sooner than later.

Only the Plan at the moment John, Still have to make it happen.

I suppose I could locate one of the 100lb tanks at the compressor.
Its going to the far side of the barn to limit noise.
Even though its not that loud.
Have a five gallon below and just use a union to connect/disconnect it for draining.
but from there its a rise of 14' to the rafters.
and 50' run to where I plan on placing the other tanks.
with another 5 gal trap reservoir below them and the supply line rise up from there so any moisture making it that far will get to drain out.

I was thinking of making a DIY drier from a old mini-fridge,Idea there is a reservoir filled with water an coiled pipe inside.
Rather then run the compressed air through the drier,the incoming air would go through it.
Compressed airs gets pretty hot, and from what I read on some diy its hard for the fridge to keep up.

I have to think though, most of them just put a coil in the fridge,no thermal mass.
Plus they are trying to condense hot air vs room temps.
Just pull out a cold beer on a humid day, doe not take long for a puddle to form.
