One could look into a set of three or four concentrators that are rated at 8 to 10 psi at 5 LPM. Three would be the minimum for consideration if the output is set at 4 LPM to achieve a higher O2 output.
There are firms that make commercial units that will supply the necessary output. However, the cost is much higher than used medical units. It would be nice to locate a fellow lampworker in your area that is using concentrators and yet willing to test your torch on their system.
