FAQ
1.Q. What is an Oxygen Booster Compressor?
A. It is a specialized compressor that increases the pressure of existing oxygen gas from a primary source (like an oxygen plant) to the required high pressure for storage, transportation, or end-use applications.
2. Q.Why is Oil-Free Design Critical?
A. To prevent any risk of contamination. Our compressors use oil-free technology to ensure 100% pure, medical-grade oxygen, which is essential for patient safety and industrial process integrity.
3. Q.What are the Main Applications?
A. Primarily used in hospitals (to boost PSA/VPSA plant output), medical oxygen filling stations, industrial gas production, and any process requiring high-pressure oxygen supply.
4. Q.How is Safety Ensured?
A. They are built with oxygen-compatible materials, feature advanced monitoring for temperature and pressure, and incorporate multiple safety valves and purge systems to prevent fire hazards.
5.Q. What are the Key Maintenance Needs?
A. Regular inspection of seals and valves, periodic replacement of non-metallic components, and monitoring of filtration systems to maintain purity and performance.
6.Q.Can it be Customized?
A. Yes. Pressure ratios, flow capacity (Nm³/h), cooling methods, and control systems can be tailored to integrate seamlessly with your specific oxygen generation plant and end-use requirements.
