This compressor is generally suitable for oxygen pressurization and recovery occasions such as filling and inverting bottles under
the working conditions of rated inlet pressure 0.4Mpa (there configured a pressure reducing valve once the suction pressure over
high pressure then it should be reduced down to 0.4Mpa by manual) and a rated exhaust pressure of 20Mpa . If the compressor is
used under special working conditions where the inlet pressure is lower than 0.4Mpa and the exhaust pressure is higher than 20Mpa,
it is necessary to communicate with our company's technicians before production and use.
