Personal Oxygen Generator (O2-Balance) It is generating the best Oxygen concentration (30%) for human body.It is adopting "Safe Membrane Oxygen Generating" What is Personal Oxygen Generator (O2-Balace) "O2-Balance" is a portable oxygen generator, most efficient, economical and safe.- Oxygen Concentration in area -1. Main Capital cities: ~ 20.8%2. Residential in Capital cities: ~ 20.5%3. Forest, Mountain area: Approx. 21.6%4. Seaside: Approx. 21.8%5. O2-Balance: Approx. 30% * 30% High Purity Oxygen 1.5 times of airborne oxygen concentration! The high-purity oxygen of 30% concentrationThis allows you to feel much higher oxygen effect with more than about 2 times of 0.4;per minute, which is the required amount of oxygen for an adult. * 2,000,000 Anions -2 Mega EMS Anions High-tech EMS anion! In terms of an anion, which is called the vitamin of air, it offers much more pleasant environment of an anion than in the forest or a waterfall, through providing 2,000,000 anions per 1cc of air. 3 +1 Clean System The 3 +1 clean system, which added mega anion to 3-step clean system, the same class as the air cleaner, provides high-purity oxygen air more cleanly. (The clean function of this apparatus offers only clean function of small capacity as to high-purity oxygen supply.) - Oxygen Supply: 3 LPM - Timer: 10, 20, 40 mins.- Oxygen concentration: 30(3) % - The principle of oxygen generation: Oxygen Membrane- Size: 250 x 340 x130 mm- Power: 220v, 60hz - Weight: 4.5kg- Power Consumption: 60WIt is generating the best Oxygen concentration (30%) for human body.It is adopting "Safe Membrane Oxygen Generating" What is Personal Oxygen Generator (O2-Balace) "O2-Balance" is a portable oxygen generator, most efficient, economical and safe.- Oxygen Concentration in area -1.
