I would also highly recommend DIN fittings on any internal tanks due to their captured o-ring design. Being a scuba instructor in the past, I’ve seen too many o-rings blow on yoke connectors which wouldn’t be good in an enclosed 1 ATM environment.

External or internal? And are you set up for high pressure or not? HP air can be had with a simple yoke (like a first stage without the regulator). If you need lower pressure, then the first stage will work fine. George carried his internally, which was an issue at depth because scuba first stages can only be cranked up to about 150-160 pounds. Externally, you get that over ambient, which gives you full flow. The only other issue is flow. The 1st stage arrangement is pretty slow. Vance

Message----- What have any of you done to hook up standard SCUBA tanks for HP air source. Originally I was using a large steel tank. It is just too heavy to handle and I am switching to twin Aluminum 100 tanks.
I am thinking a scuba first stage regulator is used with an adaptor at the thru hull connection.
Appreciate any help
