Traveler HP Portable Nitrox Generating System

The Nuvair Traveler HP 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 EANx40 at 3600 psi (248 bar).

7051-HP / 7051-HP-G

The Nuvair Traveler HP 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 (LP) air source to make nitrox. High pressure (HP) 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.
