The Voyager IV Commercial compressor package integrates two compressors into an enclosed cabinet with large, easy-to-remove access doors for maintenance. The cabinet reduces compressor noise and offers a nice control panel on the front for easy operation. Using an EK76 LP compressor and Coltri HP compressor, we are able to provide 22% to 40% enriched air nitrox at 9.3-17 CFM (263-481 L/min) FAD.

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.

The Coltri/Nuvair Mini Tech high pressure (5000 psi/345 bar) gas powered compressor can be used in a wide variety of applications including breathing air and industrial air use. Compact in design with foldaway handles, the Mini Tech is portable and easy to lift. On-board Grade E air purification comes standard for breathing air quality output. With several options available to meet your specific needs, the portability and dependability of the gas-powered HP Mini Tech MCH13 or MCH16 makes this the compressor for you.

The Nuvair Mini Tech air compressor uses a pumping unit that is made from top quality materials; connecting rods from aluminum alloy, stainless steel intercoolers and aftercoolers that are more than four meters in length and cylinders of special cast iron. The marine grade 6061 aluminum frame is corrosion resistant, rigid and lightweight.
