Inspection-Friendly, Non-Pressurized Reservoir Design

LiveO2 reservoirs use a white exterior to support easier visual inspection and includes a zipper with an inspection/drainage port for internal inspection, rapid drainage, and care access when needed. The reservoir is designed to avoid sealed pressurization, allowing excess gas to escape rather than trapping gases inside the air compartment.

The LiveO2 Dual User Extreme is available with a 20 LPM standard configuration and optional 30 LPM or 40 LPM upgrades for faster reservoir refill performance and higher hourly user capacity in higher-use environments. The 20 LPM setup is designed for simultaneous two-user operation, has an approximate 20–25 minute fill time, and can support up to 3 users per hour depending on session structure and facility workflow. The 30 LPM setup can support up to 4 users per hour, while the 40 LPM setup can support up to 5 users per hour, making these upgrades especially useful for clinics, recovery centers, athletic facilities, wellness studios, and high-capacity home environments. Users can also choose between a hanging reservoir setup or a frame kit system, depending on room layout and preferred installation style.

The LiveO2 Dual User Extreme is designed primarily for professional indoor environments such as clinics, recovery centers, athletic facilities, wellness studios, and performance training spaces, with secondary use in advanced home gyms or dedicated wellness rooms. Space needs depend on the selected reservoir mounting option, air separator configuration, tubing layout, and the exercise equipment used for two simultaneous users. The Extreme dual-user reservoir measures approximately 7 feet high by 5 feet wide, while the optional frame kit measures approximately 8 feet high by 6 feet wide.

For commercial or high-use home setups, allow room for the dual air separator system, tubing pathways, two mask connections, and two exercise stations such as bikes, treadmills, rebounders, or other approved equipment. Each air separator measures approximately 30 inches high by 15 inches wide by 17 inches deep and should have about 8 inches of clearance around it for proper airflow.
