Identify this compressor?

[kmev]

Got a small compressor tonight off Craigslist for $20. Had been using scuba cylinders for air, but figured this was too good to pass. It was set up for airbrushing with a regulator and the cut-off set to 80 psi. Lifted my Handy-lift just fine but not quite enough for my impact, so I removed the regulator and increased the cut-off to 100 psi. Then I noticed water leaking from the seam on the bottom of the tank - real bummer. Backed the pressure down again and it stopped leaking. Not sure what I should do with it now. Not going to take it back - the seller had no idea the tank was bad.

I know it's a long shot, but can anyone identify this pump? There are no marking on it anywhere. It's not very large.

if you have any leakage from a pressure vessel, well , if i gotta/ got to tell you.........................

Stop using it NOW! This is nothing to fool around with - the tank could blow apart starting at a point where weakened by rust out/pin holes. Get a new tank or even a used tank that will pass a hydrostatic test before use.

Remove the compressor and motor. Cut the tank in half and use it for flower pots in the back yard with a few more drainage holes.

A replacement tank either new or pressure tested will cost you more than a new compressor unless you happen upon one at a garage sale. Garage sale units may be in bad condition also. Save the parts for spares if you want to but otherwise the unit is worthless.

Are you sure that the water does not come from a drain-valve?
If it does come from the weld, like Steve say, stop using it! There's some serious amounts of energy in there.

Scuba cylinders?? That doesn't ring true. Scuba tanks are normally filled to 2000 psi!!! not 100psi. Maybe he was using the scuba tank for tools only. I found this site http://www.saltypig.com/scuba/

As for the compressor, @ 100psi and a surface area of lets say conservatively 10 ft2 that's 144,000 pounds of force that could kill. Would you stand under a 144,000 pound load that you know the rope holding it up was defective? I agree with Torque 1st -flower pots.

I think, If you read it again, you'll find kmev was using scuba tanks for his own air supply until he found this compressor...

 

[kmev]

Yes, the compressor was to replace my scuba cylinders (which work pretty darn well, by the way, and last longer than you'd think!).

Working the scuba industry I understand the seriousness of explosions, so I don't plan on using it. I'll probalby look around for a used tank that doesn't have the same problems.

One lesson learned here - don't buy a used compressor that doesn't have a working drain valve!

Anyone recognize this beast at all?

My guess at first glance was a "Speed-Air" but I can't really back that up as a search didn't yield a like item.

If you are interested in a new tank, I think it will be hard to beat the price at Surplus Center. 20 gal @ $129.

If I'm going to invest over $100 I'd rather buy a bigger compressor. I put this on back on Craigslist, but stated the tank needed to be replaced. We'll see what happens. It does have some good parts.

Kmev what part of the country are you in I have a spare 70 gallon tank I have been looking at selling it was made in 1951 and is quite stout most likely twice the steel in it as my newer 60 gallon tank.

I'm in southern WI, and I don't think I'd have room in my garage for a 70 gallon. I think this one is a 7.

Kmev shipping would kick your tail anyways .

if it is a weld seam that is leaking and the remainder of the tank is on good shape, I wonder what it would cost to have it repaired.

there are people that make boilers for live steam locomotives and they have high pressure in them. there are also people that are certified to weld pressure vessels.

I just cant help but wonder what the cost would be

More than likely Bob much more than the tank is worth plus if a sem is leaking chnces are the tank isnt worth repairing due to rust on the inside.

The drain valve was replaced with a plug and the first thing I did was drain the water when I got it home. The plug came out easy and there was less water in the tank than I expected so assumed it was drained regularly, but apparently not often enough. It was only $20, so it's really not a big deal to me. I do appreciate all the replies.
