Got an idea, tell me what you think.... Theres been alot talk about a nitrogen push systems to stop pressure drop. What about using 2 bottles and pressurize them to ,lets say 1500 each (thats only half of what the disc is rated for so it should be safe). Run a check valve on both and run them into a y-block, then into a pressure regulator that will keep your line pressure at whatever you desire? Let me know what you think about that cause I think i'm gonna be doing some experimenting with this and would like to hear your thought's on this. Ken

The problem with this scenario is flow. Sure you can regulate the pressure with the regulator...but not flow. The flow through a given regulator will be dependant on the pressure.
Heres a scenario to help you understand. I use and impact gun on big bolts. My compressor runs at 125 psi and I can keep the trigger down for as long as I want and the impact gun will operate.
For hard to loosen bolts that 125 psi wont do..i use my nitrogen bottle with 3000 psi regulated down to about 350 psi and hook that to the impact gun. It GOES LIKE HELL....for about 4 seconds...then dies off because the regulator cannot keep up.
Now if you had a regulator that had a very large flow capability....say a 500 shot at 1000 psi...and then you used a jet in the nozzle...it could work. But I personally do not know of any regulators offhand. Im sure they are out there. but youll have to look hard.
So again...its not just pressure...but flow rate thru the regulator at a given pressure and then matching that to your system requirements. Your probably gonne need a regulator that is capable of flowing 80% more than your largest shot to keep things consistant.

Keep your pressure at about 950/1000psi and dual bottles, and you see minimal pressure drop. The higher the pressure you start with the higher the psi lose after a run. here's mine tee'd into one line, 30lb's worth. Then click heater on, on the return road and you're ready for a back to back run.
