Dive industry leader in air, nitrox & multigas technologies.


Nuvair is an international manufacturer and distributor of dive industry compressed gas solutions. Based in California and with over 30 years’ experience, our high-pressure compressor systems, nitrox generators, fill panels, gas analyzers, boosters, and fill containment stations are used in dive shops, liveaboards, and dive boats worldwide.

Nitrox Systems
Nuvair pioneered the production of enriched air nitrox (EANx) using semi-permeable membranes. Our systems produce 21% to 40% nitrox on both low- and high-pressure compressors. We offer standalone turnkey nitrox systems or nitrox generators that work in-line with your existing compressor system. Trimix upgrades are available.

Support After the Sale
We do more than just sell compressed gas equipment. We support and service the equipment we sell throughout its service life. Help with your Nuvair products is just a phone call or email away.

Custom-Built Compressors
We understand your needs may differ from the solutions provided by standard compressor packages. With all manufacturing done in-house, our team can design and fabricate a unique system for your vessel, dive shop, or other mobile application.
