This back pressure regulator seems to be a good solution as well. It's a bit bulky and not plug and play. If already you have a coltri filter housing then Pressure maintenance valve for portable compressors | Coltri Compressors seems to be the better solution.Nice set up! Like the doubles...try contacting these guys...ask for "Ron", he was great source of information when I bought my MCH-6 Icon... https://nuvair.com/1-4-fnpt-to-1-4-mnpt-6000-psi-back-pressure-regulator.html..
"zero" CO....good....we used to put bottles in large tank to reduce heat during compression/filling, but unless you have a LOT of time and ice water, the drop in pressure from heated air to ambient is unavoidable...again just my experience...your mileage may vary..
