All liquid oxygen systems consist of two essential components – the reservoir and the portable. A liquid oxygen system provides the oxygen user with pure oxygen and does not require any electricity.


A liquid oxygen reservoir is a larger tank, usually weighing over 55 kg (120 lbs) and standing over 0.75 m (30 in) in height. The reservoir typically sits stationary in an oxygen user’s home environment and contains actual liquid oxygen. The primary function of the reservoir is to fill the liquid oxygen portable units for an oxygen user to utilize while being active or away from home. Also, the oxygen user can breathe continuous flow directly from the reservoir, or as an emergency source of oxygen is needed in the event of a power outage when the user also utilizes an oxygen concentrator.
