Help identify what brand air compressor I have

[Lenny B]

Hello Everyone,
I have an older compressor that is missing the name plate on the tank and the pump only has a casting nunber. The person I received it from said it was a Kellogg. I looked online and the pump looks like the diagram for a Kellogg 331TV. Does anyone recognize this unit? I would like to restore it if I can determine what it is to see if parts are available. Also, the tank is an 80 gallon and I believe the pump and motor are 5HP 240 single phase if that helps. Any info on this unit is appreciated.

Thanks for your help ~ Lenny B

Looks like a 321 or 325 to me. Get a picture of both side by side and you will see the cylinder block is longer on the 331 between the lowest cooling fin and the top of the crankcase. Otherwise its very hard to distinguish between them.

I think your right. I measured the width of the cylinder and it is 3" which is what the 321 should be. I could not find the diameter spec on a 331 but a 332 is 4" and I believe that's what the 331 probably is.

Thanks ~ Lenny B

A 331 should have 3 belts. LP bore of a 331 is 4.75”.
