So I need suggestions on how to push them remaining gas out of my 6k nitrogen tank into my fill bottles. So basically i need suggestions on a booster setup to equalize tanks to push gas!
Basically you can use any hpa compressor that has a dedicated threaded inlet, you don't need a booster. I use the cheapest basic YH. Filters stay dry and clean seems like forever.
You will need a nitro regulator that will take the 6000psi tank pressure down. My regulator goes down to lowest psi of 200, way to high for YH inlet to handle. I connect it to a old r12 refrigeration gauge manifold I can set at 1-3 psi with YH running and filling my tank, but any refrig manifold gauge set should work fine. Some compressors might take more inlet pressure than others, idk, but they all should work ok. As long as you can regulate the inlet pressure between 1-5psi on a YH it works perfect. To high a YH inlet psi screws with the oil sump and load on motor. I can drain a 6000psi nitro tank down to under 20psi getting my monys worth using every drop of nitro. Unlike having to return a big nitro tank for a full refill when its at 2900psi.
You must keep an eye on the inlet pressure and adjust it as needed. The lower the nitro tank gets the more you need to open up the manifold to keep inlet pressure above 0psi.
When my nitro tank is at 2000psi or above might have to adjust the inlet pressure up once or twice while filling a tank if i start at 2psiYH inlet psi. The lower the nitro tank gets the more you have to watch/increase manifold inlet pressure from the nitro tank to YH. At 2psi YH inlet pressure, it fills my tank in 2/3 the time vs no inlet nitro.. Keep an eye on YH oil level, don't go to high on inlet psi...
I haven't done a dual regulator set up yet, but regulators are available for low pressure operations that could do all this automatically. Haven't seen any nitro regs that can go accurately from 6000-1psi so 2 must be used inline for this type of totally automatic operation. So eventually I will get another regulator that can put inline with my 6000>200psi reg, that can take in the 200psi and regulate it down to 1-5psi high volume...
Do at your own risk...
