Nuvair LP Nitrox Generator Silent Series
The LP Nitrox Generator series uses a rotary screw compressor to produce enriched air nitrox that is 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). Available in six models mounted in a silenced cabinet, the nitrox delivery rates range from 17–65 CFM (480–1840 L/min) FAD @ 32% oxygen to 10–38 CFM (280–1019 L/min) FAD @ 40% oxygen.

The low pressure (LP) Nitrox Generator series uses a rotary screw low pressure (LP) compressor, air/oil aftercooler, 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. The model shown is equipped with an optional refrigerated air dryer.
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.
