At the top of the Nitrox line, the LP600 ROTARY system consists of an industrial screw compressor that delivers air at a pressure of 8 bar to a membrane that separates nitrogen and oxygen at atmospheric pressure until Nitrox 40% O2 is obtained and can be compressed at a pressure of 232 bar in combination with a high pressure compressor. The percentage of oxygen obtained at the outlet can be regulated from 22.4% to 40% using a valve directly accessible on top of the compressor. Exclusive to the the Heavy Duty line compressors.
