O2 concentrator help and information - OG20, Intensity 10, other??
I am wanting to purchase a phantom (I currently have a 15+? year old Nortel major/minor). I am running on an 02 cylinder now. It’s a hassle refilling and I will be setting up my new torch in a remote area where I cannot access O2 by pick up or delivery. I also have little time at my torch, so don’t think I’ve got a lot of hours behind me with a 15+ year old torch! I want to set up both locations so that I can grow with ability and projects (eventually use boro to blow goblets and other things). I want the ability to power both torches fully. So far I am gathering information regarding the OG20 and the Intensity 10. Happy to have info regarding other options. So far my questions are:

1. Does the OG20 and Intensity 10 - run at 8 or 10 PSI max?
2. any preferences, pros, cons between the 2 concentrators?
3. how many of the above concentrators to run a GTT phantom fully?
4. how many of the above concentrators to run a nortel major fully?
5. new compressed air option on the GTT phantom - will this effect the amount of O2 I need to get the same results?
6. new compressed air option on the GTT phantom - is it hard/easy to learn how to adjust heat/flame with compressed air?

If anyone has the time to help me with the above questions, provide any other information that I don’t even know to ask, or can recommend other concentrators/generators/torches and their combinations, I’d really appreciate it.
