Coltri Sub LP 300 ROTARY SILENT WITH INBUILT DRIER

The LP300 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.
