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.

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.
