“FunGun”If the compressor was turned over, you could have too much oil in the valve systems of the cylinders.  It might start working better after sitting for a few days.  (here again I would check with the dealer on his opinion).  You will always get a little oil in the water separator discharge so don’t think something is wrong, this is normal.  I usually catch my discharge in a one gallon jug just so I can monitor the amount of moisture and oil.

back to troubleshooting:

If you are able to purge the separator, which you are when you see the “chicken soup”  (which is normal when there is oil mixed with the water) then you are getting high pressure to that point.  So it sounds like the problem might be between the filter output and the valve at the guage. 
Do you notice the whip getting stiff at all when you pumped for several minutes? If not then there is no air getting to the whip.  If your whip is getting stiff then I would look at the valve assy at the end of the whip.  I have had those go bad.  Also while we are on this end of the whip, are you getting any air out? 

Also you might have a check valve between the SCBA and the quick disconnect, it could be bad or even just backwards?

(I have owned a larger bauer but not one of the juniors, so I am not completely familiar with how you would normally purge the high pressure line to take your tank off. )
Is there a purge on the SCBA adapter pictured between the valve and your tank attach point? 
Or do you have to relieve the pressure down at the base of the filter/separator port block?

Might try taking the fill whip off without any pressure in the system.  I don’t know if you have compressor experience but if a fitting has any pressure on it at all you won’t be able to break it loose so make sure to depressurize the system before trying to wrench on it.

If your distribution block has a second port you might check to see if it has airflow when running.  Just keep working your way back to the 3rd stage separator since you know your getting pressure there.

IF you would like to visit over the phone, PM me and send your phone number and I will call you.


!st, thanks for your input.
I was catching the discharge in a clear container. One thing that really caught my eye, the 3rd stage pure line was a little dirty inside the hose before I did the 1st purge. Afterwards completely coated with the discharged milky looking substance. To me, this is an indicator the discharge had never been this color.
This is my 1st time operating a HPA compressor so it is a learning experience no matter how may weeks I have been reading. The pressure of the purge did seem to have pressure behind it, if what would be considered normal pressure, I have no idea. The 3rd stage had much more pressure than 1 and 2 which I would think would be normal. To add one thing that may be pertinent, with the oil buildup inside the intake filter housing which is on the same side as the 3rd stage may indicate the compressor was laid over on that side, which is also on the side the 3rd stage is on. I do not know if that may be a factor. I did not check the fill whip, it had been used with this setup the week before by the dealer filling 2 tanks last Friday with normal operation. I had asked him to to insure it was functioning properly before shipment, he agreeded.
No, the whip is not getting stiff at all and no air is coming out the end of the whip. I put a finger tip over it and cracked the valve, nothing, then even took a tissue and held it over the end of the whip, no movement. I did not inspect the check valve, but as said above, it had been used to fill tanks with this configuration just before shipment and was fine. Yes, there is a bleed valve between the bleed valve and my tanks, but with no pressure , I never hooked the tank to the fill whip. I was waiting for the compressor to show pressure before attaching it. I have no HPA compressor experience but was trained to deal with high pressure Liquid Oxygen back in my USAF days. I know not the same as the oxygen system had much more pressure, but same principal. There is no secondary secondary port, built to charge one at a time.I will send you a PM, would enjoy speaking with you about the issues. I have tried everything I know, from reading and past experiences with the liquid oxygen as mentioned. IMHO, I really think it has to do with the shipping and FedEx having it on its side at some point during shipment.As I have said before, I asked specifically if they were going to drain the oil, which I was told no. Seems FedEx paid no attention to the sign on the container.
