Nuvair HP Traveler Portable Nitrox Generating System

7051-HP / 7051-HP-G

The Nuvair Traveler efficiently and cost-effectively produces nitrox using gas or electric power, without the hazards or expense of pressurized oxygen blending. Supplies air or generates enriched air nitrox up to 40% at 3600 psi (248 bar).

The Nuvair Traveler nitrox system allows for efficient and cost-effective nitrox production using gas or electric power, without the hazards or expense of blending with stored high pressure oxygen (O2). Instead, the system uses a semi-permeable membrane to produce nitrox from air. A portion of the nitrogen in air is separated out, leaving an oxygen-rich nitrox mixture. This nitrox mixture can be pumped up to a maximum pressure of 3600 psi (250 bar) when filling scuba cylinders.

The nitrox membrane requires a low pressure air source to make nitrox. High pressure air from scuba cylinders or storage tanks—along with a regulator—can be used to supply this LP air to the membrane system. Simple-to-operate, reliable and versatile, without the hassles or hazards of oxygen partial pressure blending. It is also portable and lightweight, making for easy transport.

The Traveler is designed to fill scuba-sized cylinders, not larger storage tanks.
