Oxygen Concentrators Manufacturers

Oxygen concentrators are molecular sieves that separate nitrogen from oxygen and can usually provide 90-95% oxygen at flows of 4-6 L/min. Humidity can be added to the system by the attachment of a bubble humidifier. These are quiet, produce little heat, and usually weigh no more that 40-60 lb. These also require very little maintenance and are equipped with alarms to warn if the oxygen concentration falls below a critical level.
