The CAIRE Companion Portable LOX Liquid Oxygen Unit provides freedom so you can live the active lifestyle you want when receiving oxygen therapy. The unit's shoulder strap creates a comfortable way to carry the unit when walking, shopping and traveling. It also runs quiet and does not require batteries.

Operation is made simple for both the 1000 and 1000T with valve to select the necessary liters per minute as prescribed by the doctor. The Companion 1000 standard flow control ranges from .25 to 6 liters per minute and the High Flow Companion 1000T ranges from .5 to 15 liters per minute. Caire designed the buttons with a recessed profile to minimize accidental bumping that can change the settings. This profile also reduces damage to the controls. Operation time depends on setting but on average at setting 2 it will run approximately 7.7 hours.

When ready to fill the Companion Liquid Oxygen Unit is placed into a vessel reservoir for a cost effective way to replenish oxygen.

Caire also manufactures other portable options for liquid oxygen. Check out the HELiOS to accommodate pulse flow and continuous flow.
