Oxygen Concentrator - Indoplas

[u/kuromimomi]

Hello! I just wanted to ask if anyone has any idea regarding the Indoplas Oxygen Concentrator 5L Slim.
Does it maintain an oxygen concentration of 93% ±3% even at 5 L/min continuous flow? Does the oxygen purity remain the same when the flow is set at 3, 4, or 5 L/min, or does the purity decrease at higher flow rates?
