Never be without oxygen cylinder refills! Oxy2Go's refill pak includes 6 refill oxygen cylinders for the Oxy2Go portable oxygen system. Each oxygen cylinder contains oxygen-enriched air, made up of 90% Oxygen (O2) and 10% Nitrogen (N2). The oxygen-enriched air in the cylinder is pressurized and provides approximately 14 one second blasts of oxygen per cylinder. The oxygen-enriched air in the cylinder is completely free of any contaminants or pollutants found in normal atmospheric air and polluted environments. Once depleted, the empty cylinders can be recycled or disposed of properly. |
