Element HP High Pressure Nitrox System


The Element HP Nitrox System makes oxygen-rich air (nitrox) then compresses it with a high pressure (HP) compressor for filling scuba tanks or storage cylinders. The package is designed to be lightweight and portable, with an open frame for excellent access to components yet protection from moving parts while it is running.

The Nuvair Element HP makes high pressure nitrox (22-40% oxygen) from an existing low pressure or high pressure air source for nitrox tank fills up to 3600 psi (250 bar) or air fills up to 4500 PSI (310 bar). Although it is described as the "nitrox compressor," it can also be used to pump air. The Element HP allows for efficient and cost-effective nitrox production using diesel, gas, hydraulic or electric power, without the hazards or expense of blending with stored high pressure oxygen (O2). The Element HP has LP filtration and an air heater to clean and heat the air delivered to it. The two most common sources are an LP compressor (LP supply option) or HP air storage tanks (HP supply option). Information on Element HP's optional compressor packages is provided in the Element HP Nitrox System Operation Manual.
