AirCompressor Check List?

greets folks, have been shopping for a new (larger) air compressor for the shop and i think i found one. will have a look at it this weekend. am hoping to pick up some pointers on what to look for (ie potential problems).

its relatively big (to me) ... 100 gallons i think ... it has two standard piston compressors and two motors (one for each compressor).

owner tells me he recently changed one of the compressors (in fact it looks new) and that it 'runs like a charm'. though he tells me that it makes alot of noise because its the 'old style' and he's upgraded to a screw-type compressor.

to be honest, other than just firing the thing up, and checking to see that it delivers some air, i'm not sure how to make a good evaluation of its condition.

kick the tires?

thanks,

-tony

What make are the pumps? Is there oil in the tank drain? I assume power won't be an issue.

not sure what pump make they are.. but what would oil in the drain be telling me? and how long would it have to run for oil to be present there? (i assume the guy will have drained it / cleaned it before letting me try it)

will setting it for highest PSI and letting it run tell me anything? should the pumps get hot fast? etc.

thanks

Carefully look over the tank for excessive rust, especially near the drain hole. I would have suggested removing the inspection port but I have no idea what to look for after doing so.

I'm thinking of ring condition. The drainage will have a small amount of oil in it normally but if it's excessive or smells burnt, there might be trouble.

Depending on rpm and psi the pumps will heat-up faster or slower. If the heating is excessive like burning smell or baked on spoo, it might need valve work.

It would be a good idea to dissassemble the valves and clean them anyway.
