Water Cooled LP Marine Nitrox Generator Series
The water cooled low-pressure (LP) Marine Nitrox Generator uses a rotary screw compressor to produce low pressure oxygen-rich air (nitrox) for delivery to a high-pressure (HP) compressor for scuba tanks or storage cylinder fills in high demand applications. Its compact size, low amp draw on start-up and marine grade aluminum frame make it perfect for below deck installations in hot engine rooms. Available in five models, the nitrox delivery rates range from 17–36 CFM (480–1216 L/min) FAD @ 32% oxygen to 10–21 CFM (280–713 L/min) FAD @ 40% oxygen.
