Like the previous model in the ActivOx family, the Activox 4L features the same unique Auto Mode and Pulse Wave Technologies that work together to deliver oxygen equal with the user's normal breath rate and breathing pattern. This intuitive technology results in a quiet, gentle delivery of oxygen to help minimize the uncomfortable side effects such as dry nose and sinus irritations that are often associated with other types of pulse-dose delivery oxygen concentrators.

The ActivOX 4L Portable Oxygen Concentrator with patented Auto Mode Technology and Pulse Wave Delivery is capable of providing Oxygen up to a setting of 4 and is recommended for 24/7 use.   

  • Auto-Mode is an inherent feature that automatically detects changes in your breathing patterns and adjusts the unit's breath detector sensitivity accordingly to provide oxygen during all levels of activity during the day and throughout the night while at rest.  
  • The Activox 4L oxygen concentrator utilizes Pulse Wave delivery technology which is triggered on demand by the user during inhalation. The PULSE-WAVE Breath Detection Symbol will flash as you breathe. This is confirmation the device is delivering a dose of oxygen with each inhaled breath. If you stop breathing through the nasal cannula (mouth breathing), the 4L unit will begin delivering doses of oxygen automatically and will continue to automatically provide doses of oxygen until normal breathing resumes. 

Not only can the the Activox 4L deliver up to 4 liters per minute of oxygen but this device offers users a "best in class internal battery runtime" -- up to 10.25 hours of re-chargeable internal battery runtime. For oxygen users requiring additional battery life there is an optional powerful, lightweight, external battery available which provides up to 4.75 hours of supplemental battery runtime.  

The Activox 4L is FAA-approved for in-flight use on all domestic and international commercial airlines, making it the ideal portable oxygen travel system for long trips and vacations. The New ActivOx 4 L features a simple 'push button'  and easy to read display which simplifies operating your ActivOx and helps to reduce troubleshooting calls. The ActivOx 4 L comes standard with a custom carrying case allowing you to; carry the device with a briefcase handle, wear over the shoulder, or configure to be worn as a backpack. Your ActivOx 4 L system comes with both a AC (wall) Charger and DC (Vehicle) Charger to recharge your Activox's batteries.
