COMPANION LIQUID OXYGEN SYSTEMS
The Companion Liquid Oxygen System is designed to store and deliver
oxygen at a prescribed rate. The system consists of two units: the
Stationary and the Portable.
Stationary Units
Each Stationary is a liquid oxygen reservoir you may use to fill your
Portable unit. There are two basic types of Stationary units: a standard
unit that you may use to supply breathing oxygen in the home (including
Companion 21, Companion 31, and Companion 41); and a Low Loss unit
(Companion 31LL) that allows liquid oxygen to be held for much longer
periods of time than a standard Stationary unit but does NOT provide a
direct source of oxygen for breathing purposes.
Your liquid oxygen supplier must periodically refill your Stationary unit.
The frequency of refill will depend upon your rate of oxygen use.
