Coltri/Nuvair LP300 Rotary Nitrox Generator

The Coltri/Nuvair LP300 rotary nitrox generator consists of an industrial screw-type compressor that delivers air at a pressure of 175 psi (12 bar) to a membrane that separates nitrogen and oxygen up to a maximum percentage of 40% oxygen (O2). The enriched air can be compressed at a pressure of 3365 psi (232 bar) in combination with a high-pressure compressor. The percentage of oxygen obtained at the output can be regulated from 22.4% to 40% thanks to a valve accessible directly on top of the compressor. The oxygen analyzer allows to verify the correct percentage regulated through the appropriate valve. Available in two power configurations: 208-230V/E3/60Hz and 415V/E3/50Hz.
