The design presented here can be implemented with different subsets of components and different sources for each component. The following configurations are useful representatives:
| Name | Valve | Flow-Meter | Comments |
|---|---|---|---|
| Full-SMC-S | SMC PVQ31-6G-40 | Siargo 4800 | Closed-loop with off-the-shelf components |
| Full-SMC-H | SMC PVQ31-6G-40 | Honeywell | Same but with different flow sensor |
| OL-SMC | SMC PVQ31-6G-40 | None | Open-Loop with off-the shelf valve |
| Full-SMC-OS | SMC PVQ31-6G-40 | Open-Source | Closed-Loop with off-the-shelf valve and open-source flow-sensor |
| Full-OS-OS | Open-Source | Open-Source | Closed-loop with all open-source components |
| Dual-SMC-H | 2xSMC PVQ31-6G-40 | Honeywell | Dual solenoid valves for in-unit air-oxygen blending |
| Dual-OS-OS | 2x Open-Source | Open Source | Dual open-source valves for in-unit air-oxygen blending |
