What type of oxygen concentrator or oxygen tank should I use with the Pumani?

You can use either an oxygen concentrator, oxygen tank, or walled oxygen with the Pumani. You will need an oxygen source that provides up to 10 liters of oxygen flow. You do not need a specific type or brand of concentrator or tank, but the oxygen pressure should not exceed 34.5 kPa or you might damage the Pumani.
