This oil-free, high-pressure oxygen booster compressor is specifically designed for boosting low-pressure oxygen to 5–25 bar (72.5–362.5 psi) for direct cylinder filling. With a flow range of 20–80 m³/h (0.33–1.33 m³/min) , it is the ideal solution for small to medium-scale oxygen filling stations, medical oxygen systems, and on-site oxygen generation plants.
Built with oxygen-safe materials and 100% oil-free compression, it guarantees pure, contamination-free oxygen output – critical for medical, industrial, and high-purity applications.
Oil‑Free Operation – Delivers 100% pure, contamination‑free oxygen, essential for medical and industrial filling applications.
High‑Pressure Boosting – Pressurizes oxygen from low inlet up to 5–25 bar, meeting cylinder filling requirements directly.
Flexible Flow Range – Flow adjustable from 20 to 80 m³/h, suitable for small to medium‑scale filling stations with variable demand.
Oxygen‑Safe Design – All wetted parts use compatible materials (copper, stainless steel, PTFE) with strict degreasing, eliminating ignition risks.
Energy Efficient – Low power consumption (3–11 kW / 4–15 hp) relative to output, reducing operating costs.
Compact & Reliable – Small footprint, few moving parts, low maintenance, and long service life for continuous duty.
Easy Integration – Designed to fit into existing cylinder filling lines, on‑site oxygen generation systems, or medical oxygen stations.
Wide Applications – Ideal for industrial oxygen cylinder filling, medical oxygen boosting, high‑pressure oxygen storage, and portable oxygen supply systems.

Industrial oxygen cylinder filling – Fills high-pressure oxygen cylinders for welding, cutting, and metal processing.
Medical oxygen stations – Boosts oxygen from concentrators or liquid tanks to cylinder pressure for hospital use.
On-site oxygen generation systems – Increases output pressure from PSA/VSA generators for storage or distribution.
High-pressure oxygen storage – Charges buffer tanks or cascade systems.
Portable oxygen supply – For field hospitals, emergency rescue, or remote sites.
1. Oxygen boosting requires special safety precautions. Our compressor is engineered with:
2. Strict degreasing – All components are cleaned to oxygen service standards.
3. Anti-static design – Prevents spark generation.
4. Low compression temperature – Multi-stage design with intercooling keeps temperatures safe.
5. Pressure relief valves – Overpressure protection on each stage.
6. Leak-tight seals – Minimizes oxygen leakage risk
