Nuvair LP280 / 300 / 450 / 600 Nitrox Generator Series

SKU
7060-7062 EK76-DRYER

The LP Nitrox Generator 7060-7062 EK76-DRYER Series uses a rotary screw compressor to produce oxygen-rich air (nitrox) ready for delivery to a high pressure (HP) compressor for SCUBA tanks or storage cylinder fills in high-demand applications. The package is designed to be fully automatic with an operator overseeing the production to maintain proper nitrox mixtures not to exceed 40% oxygen (EANx40).

This LP Nitrox Generator Series uses a rotary screw low pressure (LP) compressor, air/oil aftercooler, (optional) refrigerated air dryer, and filtration to provide the membrane system with a source of clean, pressurized feed air for separation. The air is filtered to CGA Grade D or better air quality prior to entering the membrane system so it will not damage or plug the membrane fibers. Specifications for Grade D air are provided in the User Manual appendix. The membrane system is rated for a maximum feed air pressure of 300 psi (21 bar) and has been configured to work well with the 175 psi (12 bar) maximum pressure delivered by the LP compressor.

A back-pressure regulator is used to adjust the amount of air the screw compressor produces to meet the appropriate levels for various O2% nitrox production. The air is then heated to a temperature that provides stability over a wide range of ambient conditions, is optimal for membrane permeation, and prevents moisture condensation. The nitrox system allows for efficient and cost-effective nitrox production using electric power, without the hazards or expense of partial-pressure 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 enriched air nitrox mixture. Although it is described as a "nitrox compressor," it can also pump air.
