Trying to identify air compressor

Identify this air compressor


I'm trying to identify this air compressor to see if parts are available to repair a leak.


Pics attached.

Any help is appreciated.

I cant find a label on the air compressor.
There is something very short stamped on it, but I cant make it out.

The tank has a welded on label with:

NAT'L BD. No. 198713

W.P 165 TEMP. 450 F
SH. .110 HD .095 RAD. E
DIV. 1 1981 CRN
W MELBEN PRODUCTS CO., INC.
HARRISON. OHIO

I have more photos, and can take more photos, if there is a way to add more.

Thanks in advance.

leak

This might be helpful for other Melben air compressor owners.

From this site, I found that Campbell Hausfeld bought out Melben, so I emailed (below) their customer service asking for help.

They were able to get back to me that I have a VT232605 pump, and sent a diagram.

"Customer service,
Can you help me identify my air compressor? I have a leak and need to find parts.
I have an old Melben air compressor (I believe Melben was bought out by Campbell-Hausfeld in 1961).
Picture attached.
Thank you, "

Yes, the leak is coming from the pump shaft end by flywheel.

The air compressor is hard wired, and no extension cord. I'll see if I can check the capacitor with a meter.

I'll check the check valve.

I appreciate all the help!

leak from the area of the input shaft of the compressor
by: Doug in s.d.ca.

"The leak is coming from the area of the input shaft of the compressor (not sure of right term)."

You mean around pump shaft end with the flywheel?
That suggests blowby into the crankcase.

"The tank pressure got to ~90 PSI when the motor circuit tripped (new issue)."

This is with no extension cord? Good chance the capacitor under that cover on top of the motor is bad.

"The leak dropped the pressure from ~90 PSI to ~70 PSI in 10 minutes."

There's probably a check valve between the tank and the output tube - if so, that's leaking, too.

I used an automotive stethoscope to try to find the location of the leak, but was unsuccessful. I'll have to try some soapy water next.

The tank pressure got to ~90 PSI when the motor circuit tripped (new issue).

The leak dropped the pressure from ~90 PSI to ~70 PSI in 10 minutes.

240V

Does it not ever reach cut-off and stop?

You say it leaks - where?

Voltage is 240
by: Jason

The voltage is 240. Unfortunately, the motor doesn't have a tag, so I don't know any of the other info.

Can you tell the motor HP, voltage, and cutout pressure?
