Air Compressor Identity

I found this in my barn. Plugged it in and it works, but the pump needs work, slow to fill tank. Any idea WHAT it is?

Looks likes it was made from an old refrigeration compressing unit. It may never pump real fast, looks like it has small pistons.

Was that barn ever used for a dairy operation? It might be a vacuum pump for the milkers.

Might be Brunner, but it looks like a home-built lash-up to me. I agree that it looks like a re-purposed reefer compressor, as it has no cooling fins. I wouldn"t trust that tank.

Pre OSHA when people were smart enough to keep fingers out of belt and fan

So maybe my best best would be to sell it for parts and get a real compressor?

UI wouldn't be too quick to scrap it. The old compressors are the good ones. Make sure you have all leaks stopped. Use it awhile. It may improve. It'll probably never be too fast, but if it just doesn't seem to be performing, remove the head & have a look at the reed valves. I like old compreseors.

I helped a co-worker test run one of those once, I think it built up over 300 psi,(without a tank) make sure you have a good relief valve on it.

Again, old refer pump. See how the air comes up through the
crankcase inlet? There's a valve in the piston to let it in the
cylinder.

I wouldn't run that sucker up with that tank!

Spin it around so the belt is next the wall. Then you're less apt to get your shirt tail wrapped up in it.
