The compressor inlet has a machined plastic three way inlet attached which allows the He in, gas to be sucked out (attached to the comp inlet) and a ballon to be attached to the top of it to monitor that your pumping with slight positive pressure. If the ballon begins to collapse you just increase the flow from the industrial reg. Too much pressure and decrease.
Hi Dave.
I really like this idea... should take all the stress off the regulator AND the compressor!
