Flow Rate and Run Times
Take the guesswork out of your setup. Instantly calculate how your tank size and fill rate translate into usable time.
Oxygen Runtime Calculation
Current: 100%
Small Flame
Medium Flame
Max Flame
| Outputs | Time (hh:mm) |
|---|---|
| Runtime before filling begins | |
| Runtime before empty | |
| Time to fill from LOW while draining | |
| Time to fill from empty when not draining |
Calculator Legend
- Tank Size: Capacity of your storage/holding tank in gallons.
- Fill/Production Rate: Total of all oxygen concentrators production in LPM. (ie. with two 10 LPM units, fill rate is 20 LPM)
- Maximum Drain Rate: Peak oxygen usage for all torches on the system in LPM. Find torch oxygen data here.
- High Pressure: Maximum pressure the system will charge/fill to in psi. (System default is 105 psi)
- Low Pressure: Pressure in psi, at which the system will automatically initiate filling. (System default is 90 psi)
- Regulator/Torch Pressure: Oxygen operating pressure in psi, that your torch or torches call for. Find torch oxygen data here.
