Low Flow:
Flow Rate: 0.5-5 LPM
, Oxygen purity: 90 - 96%
. Medium Flow:
Flow Rate: 5-10 LPM
, Oxygen purity: 70 - 90%
, High Flow:
Flow Rate: 10-30 LPM
, Oxygen purity: 30 - 70%
. With an optional plug-in module, the same unit can work in high altitudes as well (up to 14000 ft). However, the maximum flow will be reduced to 10 LPM and more than 90% oxygen enrichment will be available until 1.5 LPM.
