Hercules+Nomad 2

Anyone Use a Nomad 2 to fill a Hercules 35 or 45? The amount of air the 35 uses is nuts. 2 good mags... 3 usable mags and my fills out of my 74 CU/FT tank are running 5-6.... that isn’t a lot of rounds. I also had this compressor shipped to me defective so I am looking for suggestions as I was never able to hook the Hercules up to it and fill. Anyone use this to fill the dual 500 CC? Time to fill etc.... thanks in advance. 
 
Got the NOMAD 2 replacement today. This one at least works but the display is all jacked. First number in the display is very dim the other 2 are bright as can be. So this one too came defective but operational. Took 18 min to fill the 35 Hercules from 100-250 Bar If anyone is curious. I am going to try this for a couple weeks but with the display defective and already having one that didn’t even work out of the box I think this is going back.... just posting in case someone is curious as to fill times with this unit.
