Coltri LP250 Nitrox ROTARY for Scuba Diving: It consists of an industrial screw compressor that delivers air at a pressure of 10 bar to the Parker® membrane. The percentage of oxygen obtained at the outlet can be adjusted from 32% to 36% thanks to a valve accessible on the front side of the compressor. If connected to a compressor with pumping unit 315 (MCH 16), Nitrox at 32% can be obtained up to a pressure of 232 bar. The oxygen analyzer allows you to check the correct percentage, adjusting it through the appropriate valve.

The Coltri LP300 Nitrox ROTARY model consists of an industrial screw compressor that delivers air at a pressure of 12 bar to a membrane that separates nitrogen and oxygen up to a maximum percentage of 40% O2. The enriched air 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. The oxygen analyser allows checking of the correct percentage adjusted by means of the appropriate valve.

At the top of the Nitrox line, the Coltri 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.
