Product Info

The Liberty 2L portable oxygen concentrator delivers 1 to 8 pulse flow and weighs only 6.4 pounds.

The pulse mode is ideal for anyone who requires oxygen therapy, especially active users who don’t want to be confined to their home. When in the pulse flow mode, use a fingertip pulse oximeter to determine what setting would best keep your blood oxygen level above 90%. The Liberty 2L has a compact, innovative and easily accessible battery design that is chargeable on all settings while in use, and can be used while charging the battery using the AC adapter or DC car adapter. The Liberty 2L is also unsurpassed in safety, featuring alarms that indicate high breath rate, no breath detection, low oxygen, system technical fault, and low battery indicator, and a color LCD screen with easy-to-use control panel.
