LiveO2 – Dual User AC System


The Dual User AC System is the most complete and advanced LiveO2 system, patent pending. This system allows you to train up to two participants at the same time which equates to being able to train up to four people per hour. This is double the capacity of our 20 liter single user AC system.  The Dual User System uses the same Patent Pending Adaptive Contrast (AC) technology found in the single user Adaptive Contrast System. In addition to oxygen concentrated air, Adaptive Contrast (AC) provides oxygen depleted air at the flip of a switch. By training with oxygen depleted air your cells quickly create an increased demand for oxygen. When you flip the switch back to higher oxygen air your cells can absorb more oxygen.

  • 1 Dual AC reservoir for two users
  • 10 Mask Kits
