Main Features and Advantages

1. High Compatibility

Directly connects to standard oxygen pipelines of approximately 5 bar (0.5 MPa), eliminating the need for additional primary pressurization and simplifying system integration.


2. High Safety Level

Designed specifically for oxygen media, it features all-stainless steel flow paths, explosion-proof motors, and oil-free lubrication, ensuring safe operation under 25 bar high pressure and eliminating the risk of combustion and explosion.


3. Outstanding Energy Efficiency

This pressure range (5→25 bar, pressure ratio approximately 5:1) is the high-efficiency working range of the booster compressor. The design optimizes the number of compression stages, resulting in lower energy consumption compared to general-purpose models.


4. Stable and Reliable Output

Designed for continuous high-pressure output, it utilizes enhanced cooling and precision pressure regulating valves to ensure stable output pressure at 25 bar with minimal fluctuations.


5. Flexible and Intelligent

Can be equipped with variable frequency drive, automatically adjusting according to gas consumption, saving energy and extending service life; supports remote monitoring and fault alarms.


6. Low Maintenance Costs

Optimized seals and valve assemblies for high-pressure oxygen environments result in minimal wear, longer maintenance cycles, and easy replacement of dedicated consumables (such as oxygen filters).

FAQ

1. Q: Can the oxygen booster be used with ordinary air or nitrogen?

A: Absolutely not. It must use pure oxygen-compatible materials (such as stainless steel and special seals) and dedicated lubricating oil; otherwise, it is highly likely to cause combustion and explosion accidents.


2. Q: What could be the reason if the outlet pressure cannot reach the set value?

A: Common reasons:

Insufficient inlet pressure

Worn seals leading to internal leakage

Faulty or incorrectly set pressure regulating valve


3. Q: What should I do if the temperature rises abnormally during operation?

A: Immediately stop the machine and check:

Whether the cooling system is unobstructed (water cooling/air cooling)

Whether the lubricating oil is sufficient or has deteriorated

Whether the compression ratio is set too high


4. Q: What should I pay attention to during daily maintenance?

A: Three key points:

Regularly replace the dedicated oxygen-compatible lubricating oil (strictly according to the manual's schedule)

Use a clean oxygen source free of oil and water

Check the sealing of all connections monthly


5. Q: Are there any special requirements for the installation environment?

A: It must:

Be away from oils and flammable materials

Ensure ventilation to prevent oxygen accumulation

Use anti-static tools and grounded piping


6. Q: How to choose a suitable model?

A: Determine based on three core parameters:

Inlet pressure range

Target output pressure

Flow rate requirement (Nm³/h)

It is recommended to provide detailed operating conditions for the manufacturer to select the appropriate model.
