IR Type 30 model for 4hp?

[gasket999]

Hi folks. I’m looking for a compressor pump (bare) for a new compressor project.

The Ingersoll Rand Model 30 has always caught my eye, but I get very confused about models. There doesn’t seem to be a history page online.

I’m looking for an older pump that i can rebuild and would work well with a new 4hp single phase motor.

could anyone advise which models of the Type 30 range would work well at this power?

I suspect it would fall somewhere between the 234, the 242 and the raft of other models that have been made.

thank you.

I think my clarke se19 compressor is 4hp. 40amp breaker copes without tripping

one thing id say for the type 30's they dont seem to need rebuilding.... mates got one that we pulled out a scrap heap about 10 yrs ago its outlived several compressors ive had, gets an oil change now and then, and wears out a couple of belts after a few years

Yep. Had the house rewired and the garage on a dedicated consumer unit fed by the largest supply possible with a 45a mcb kept spare - ready for a new wired compressor.

The pump I have on my compressor is probably the one you want, I am to lazy to go
and unscrew the cover and have a look at the plate. It's a 2 belter and approx ~ 15cfm displacement
at 630rpm.

All the ones I have seen you can identify size visually. Or the number of belts.

Or you could get something like this baby:

This displaces something like 25cfm at 630rpm and would be driven with a 5hp 3phase motor.

It's not that outrageous (although a compressor is a bit of a dead start) I've an old 5hp single phase motor here that used to start/run quote happily without anything exotic.

if you put a selonid valve on them to dump the air while they get spinning it helps, 3ph motors seem to be abel to grunt big heavy things upto speed much better than singel phase motors in my experiance

Thanks guys - I’ll have a good look.

I’ve just bought a modern sealey unit in need of rebuild (see my other thread). I will keep looking for the IR T30 in the meantime, but for now I need a working compressor (plus the Sealey one will let me spray up the IR T30 when I find and rebuild it.)
