I bought an Ingersol Rand 5 HP 2 stage air compressor a few months ago and the seller gave me a couple quarts of oil but they have no label on them. Is compressor oil normally clear? It smells like oil. Feels like oil so is it the right one?
-
When in doubt Google it. I would check with the Mfg.
-
Yup Googled it and its all good. Wired it up filled with oil and fired it up . Works great now I just have to plumb it. Should there be a regulator before the chiller? There is a regulator on the press already.
-
The only regulator you need is the one one the press.
-
Thats good to know. Today my electrician wired up 3 220s, 1 for the compressor, 1 for the dryer, and 1 for the flash. Now just have to plumb it but that probably wont happen since its hard to source on a Sunday.

Gerry: One thing to stay aware of is that the total output capacity of a 5hp reciprocating piston compressor @ 100psi is probably going to be quite a bit lower than the total air consumption of your TUF 6/8 Javelin press when running at higher cycle speeds, and/or with all heads running their full stroke length. Youll know pretty quickly if your press is using more air than the compressor is producing because the compressor will be running continuously versus cycling on and off
For sure there will be many jobs where you are running the press slower or with less number of heads where the compressor will be able to keep up just fine, but running low on air is something that you will need to stay aware of. The issue on an all air machine is when the air consumption of the press exceeds the output of the compressor you will suffer a resultant drop off in air pressure, and unfortunately the first place youll see the impact is with a lack of squeegee pressure.
-
The main concern is the cfm output of that compressor. If I remember right our Jav used 17 cfm with all 6 heads going. Not having enough CFM on this machine makes it difficult to get a good print since you cannot isolate out all of the flip cylinders to increase the pressure to one head.
-
Enough Squeegee pressure on those machines can be a challenge even with an excess of CFM's, you could consider installing in-line shut off valves for the flip cylinders for the heads you'll use the least.
-
Actually with a few air fittings, the valves and some spare air line you could probably locate the valves in a convienent place on the heads. Mcmastercarr has all you'd need.
-
In my current space and the limitations of my dryer I will never realize the full potential of the press. Right now I may be able to do 180 an hour until I move the shop because I am limited on amps. Only have 100 amp single phase service. I am sure the compressor will keep up with that. And when I upgrade I plan on getting servo index/ac heads so then I will have more than enough compressor.
-
What is the CFM output of the compressor that you have?
-
14.8 @ 100 psi
-
14.8 @ 100 psi
Yeah its going to be hard for that compressor to keep up with the machine. You will want to do everything possible to minimize excess air consumption. Do like Squeegee suggested. Proper squeegee pressure on this machine is critical.

What do you mean by this?
-
My intention when buying this compressor was an Anatol Titan but it did not happen so thats what I have now.

What do you mean by this?
That with fittings and air line you could put stop values on each head *in a convenient place* for the flip cylinders to conserve air.
-
Sorry for the ignorance but I think I know what you mean. The Javelin takes 20+ cfm regardless of how many heads are printing therefore my 14.8 cfm compressor is on the short side, correct? And with fittings and airlines I could isolate the air to where I need it, am I following correctly?
-
Exactly, since your compressor is short, I was trying to suggest a fairly easy way to save air on the heads you might not use, fittings/valves/air line are cheap.

FYI, the best compressor oil I have found is the synthetic stuff from Northern Tool. Our compressor runs AWESOME on that stuff.
