Product Details & Information
Manufactured by Inogen, the Inogen One G3 system is one of the lightest and smallest portable machines on the market weighing 5.25 pounds (including the standard battery and carry case), 3.5 pounds by itself, 4.8 pounds for device and battery. The design allows the freedom and independence that are missing with traditional devices. This portable Inogen machine can be used for stationary or portable oxygen for traveling. The Inogen G3 Concentrator can be powered from three separate power sources: a rechargeable lithium-ion battery, AC power, or DC power. The AC power supply is auto-sensing, allowing worldwide use. The oxygen flow is a pulse dose with five settings from 1 to 5. Oxygen concentration levels are from 87 to 96 percent with a maximum flow of 840 mL. Noise output is a modest 39 decibels. It is capable of continued use both day and night while on extended vacations.

The Inogen G3 is sleeker, slimmer and more efficient than the G2. (pictured to the left in a comparison). The G3 employs breath detecting pulse flow oxygen, which optimally conserves energy usage and time between recharging.

Inogen One G3 Oxygen Concentrator provides Sleep Mode Technology that adapts to individual needs. Replace your cumbersome and heavy oxygen tanks that need refilling with an Inogen oxygen machine that can operate 24 hours a day, 7 days a week when you need it. No more exchanging or refilling heavy oxygen tanks or cylinders. No more bothersome regulators that require frequent adjustments. Just turn on and go!
