O2 Concepts Oxlife Liberty2 Portable Concentrator Description
Don’t let oxygen therapy hold you back. This unit is easy to use while on the road and FAA-approved for traveling on an airplane. And, the wide range of flow settings ensures you’ll get the medical-grade oxygen therapy you need wherever you go.

Oxygen Delivery
The Oxlife Liberty 2 provides oxygen delivery options that surpass its competitors. Unlike most portable units that provide only pulse-dose oxygen, this machine also offers continuous flow oxygen therapy of up to 2 liters per minute. The unit’s pulse-dose flow settings range from 1-10, with 8-80 ml oxygen boluses with each breath. Oxygen purity with this machine remains consistent between 87-95% on all flow settings.
Lightweight and Portable
Although the Oxlife Liberty 2 provides more oxygen than other portable units, the unit doesn’t sacrifice portability. The unit weighs only 6.6 pounds and measures less than 10 inches high. The unit also includes a convenient carrying bag, making it extra portable for on-the-go activities.
