Somewhere in that range - it's hard to know exactly - you can make an estimation based upon the current, but without knowing the exact efficiency of the motor you can only guesstimate.

I would agree it looks like a three hose and even has an oil pressure level indicator on the side. I had a old Champion but I could never figure out exactly what model it was because it was so old, I think it was an RE-4 last made in 1957. The tank was from 1957. I still use the tank! But it looks exactly like yours but maybe has a longer stroke. Are the side plates steel and the bottom crankcase aluminum? You can put them on the 120 gallon just mount up everything. Sell the tank for $20 for a cooker. If you really wanted to know you'd probably have to remove the exhaust manifold and measure the stroke but it may not seal up the same and it is probably hard to find parts for it. So run her until she blows which may not be for another 50-100 years. For oil changes just use Rarus 427 once and a while.

Are you sure?
Sell the tank??? Oh no thats my new smoker you are talking about. 
Yea will run the heck out of it. The 120 I found is vertical without any compressor mount. So I am going to have to figure something out for mounting it. Will cut off the mount from this tank but doubt I should attach it to the 120.
The pump should be mounted above the tank? Or can i put it like 3/4 height? Just add a drip leg to catch condensation.

There is no reason that the tank and compressor have to be mounted together. You could even build a shelf over the tank and mount the baseplate from the other compressor tank that's leaking. You could also put it on the floor with a flex tube to isolate vibration.

Looks good. I'm curious to see how long it takes to put up that tank. To 175 PSI I'm guessing 14 or 22 minutes depending on which pump it is...

Is there any sort of rubber isolation of the motor and pump to the shelf underneath? If not, you might want to consider some.

I thought that's what he was using the blue pad for?
Yea it is a interlocking floor mat I had lying around. It should work for now. I will grab some horse stall mat or the like if it wears out.
Doing some further research I believe the pump is a Ren-14. The head casting makes me believe it is the 14 instead of the 10.

Nice thread. Way to adapt to what's available. The OP wanted a stout-ish horizontal and ended up with a remote pump vertical setup.
Just curious what you are needing that particular amount of air for?
Don't get me wrong, there's never enough air, square footage, amperage, lighting, tools, boxes the tools go in, etc, etc... We can always want more.

That would be great, the 14 is an earlier version of the 15... the 10 is still a 10.
I'm not sure the 3HP setup will meet your needs though. Maybe with a small nozzle or some patience. You'll need to see and go from there.
OP . . . . you might as well take advantage of your physical setup with the separated compressor from tank to setup airline system that captures water. See prior GJ threads on Franzinator and either black pipe steel or copper airlines.

Yes that looks like a REN model instead of the R model ... another guy on here have one similar w/o the centrifugal unloader. I haven't seen R10 or R15 have any inspection plate cover at all.
Yeah was thinking of some sort of radiator in between. I don't want to get too married to this setup though I have a couple places outside the shop where I can put it once I get some stuff moved around. Though I do like the industrial look of the compressor in the shop. But will need the floor space for different things. With two cars in there space gets tight.
Yup REN-14. I just got the manuals from Michael Henager of Pacific Compressors. The cylinder numbers (NR-14-6) match the REN 14 not the smaller units so that is sweet.
Looks like the pump can be run with a 3hp or a 5 hp motor. The 5hp running higher rpms. So the motor on it and current pulley should be adequate for now but I will put the 5hp on it and a 4" pulley to put it in the 800 rpm range.

Up and running. I didnt time the fill but it was only set to 125 psi. I will have to up that to 175. I hooked it up with a 3' 3/4" hydraulic hose from tractor supply. Seemed to work well with the motor that was on there. Will get the 5 horse motor next week and see what it will do then.

It takes a lot more horsepower to get to 175psi than it does to 125psi. Do you have any way to measure the motor current? You can get away with exceeding the full-load amps for a short time, so long as the motor has a chance to cool down between run cycles.

OK you should be good then - yes, you would use an AC clamp-on ammeter.
Finally got her dialed in. Installed the 5hp WEG and the 4" pulley I bought. No go. Kept tripping the breaker. Searched around and found a 3.5" and its perfect. I thought the 4" would be close enough ~800rpm but it was putting out just a bit too much.
Should be good for another 50 years I hope.
