Product advantages of oxygen booster

1. The entire compression system is not lubricated with thin oil, which avoids the possibility of contact between oil and high-pressure high-purity oxygen, and ensures the safety of the machine;

2. The whole system has no lubrication and oil distribution system, the machine structure is simple, the control is convenient, and the operation is convenient;

3. The entire system is oil-free, so the compressed medium oxygen is free from pollution, and the purity of oxygen at the inlet and outlet of the compressor is the same.

This cylinder filling oxygen compressor is suitable for inlet pressure 3-4barg (40-60psig) and discharge pressure 150barg (2150psig)

The flow rate of small PSA air separation oxygen system of 80NM3-150NM3/hour provides clean oxygen filling service for oxygen cutting in community and small island hospitals. It can run continuously for 24 hours, and can reach more than 20 bottles each time.

Features of this oxygen booster compressor


Four-stage compression, water-cooled cooling method and stainless steel water cooler are adopted to ensure good cooling effect of the compressor and effectively prolong the service life of key wearing parts. The inlet is equipped with low intake pressure and the exhaust end is equipped with exhaust. Each level of high pressure protection, high exhaust temperature protection, safety valve and temperature display. If the temperature is too high and the pressure is too high, the system will alarm and stop to ensure safe operation. There is a forklift on the bottom of the compressor, which can be easily transferred. construction site.


Our standard high-pressure oxygen compressor has passed the EU CE certification to meet the requirements of the EU market, and can also provide customized oxygen compressors according to customer conditions.


Our oxygen booster gas compressors feature the following:

1. No oil, no oil required, stainless steel cylinder
2. No pollution, keep the gas purity unchanged
3. The quality is safe and reliable, and the stability is good.
4. Low maintenance cost and simple operation.
5. The service life of the piston ring under low pressure conditions is 4000 hours, and the service life of piston rings under high pressure conditions is 1500-2000 hours
6. According to the customer's specific working conditions, the compressor is designed as single-stage compression, two-stage compression, three-stage compression and four-stage compression.
7. Low speed, long life, average speed 260-400RPM,
8. Low noise, the average noise is lower than 75dB, it can work quietly in the medical field
9. Continuous continuous heavy-duty operation, which can run stably for 24 hours without stopping (depending on the specific model)
