1. There is a pressure maintenance valve in front of the outlet of the high-pressure compressor, which automatically opens at about 10Mpa, so that the compressed air can ensure enhanced filtration. The high-pressure compressor has been filled with lubricating oil and has been tested by the whole machine.
2. The high-pressure compressor is equipped with a breathing air filter and adopts a triple filtration system composed of activated carbon, molecular sieve and carbon monoxide adsorbent to ensure that the filtered compressed air meets the EN12021 breathing air standard
3. The final pressure is 330 bar, phase sequence protection, overload protection, oil shortage shutdown, automatic start and stop, automatic sewage discharge, time timing, oil pump lubrication, negative pressure oil saving, filter maintenance cycle reminder.

1. The use of the exhaust regulator valve ensures that the exhaust gas of the filling pump is completely and efficiently filtered by the filter, which ensures the quality of the exhaust gas of the unit, and at the same time increases the service life of the filter, reduces the operating cost, avoids gas backflow, and provides a safety guarantee for the pressurized bottle filling. .
2. The lubricating oil level and oil pressure of the unit are protected. When the unit is short of lubricating oil, the operation of the unit is automatically stopped and the user is notified by an alarm to avoid the unit running in a state of oil shortage, reducing the failure rate of the unit and prolonging the service life of the unit.
3. The full magnetic starter starts, and the non-human direct start and stop avoid the damage that the high current may cause to the operator. All starting systems are equipped with motor overload protection, which can effectively protect the unit when an abnormality occurs.
4. The use of automatic unloading system reduces the starting load of the unit and reduces the impact on the unit caused by starting. Reduced operator workload.
5. The fully automatic sewage system ensures that the air quality of the unit meets the international breathing air standards for a long time, and also effectively reduces the workload of the staff and avoids the impact of human operation factors on the operation of the unit. Automatic sewage discharge during operation, avoiding the harm to personnel caused by manual sewage discharge under pressure.
