This oil‑free, medium‑pressure piston oxygen booster is specifically designed to boost low‑pressure oxygen to 5–30 bar (72.5–435 psi) for reliable cylinder filling and high‑pressure gas delivery. With a flow capacity of 30 to 70 m³/h (0.5–1.17 m³/min) , it is the ideal solution for medium‑scale oxygen filling stations, medical gas plants, on‑site oxygen generation systems, and industrial processes requiring clean, high‑pressure oxygen.
The compressor adopts a multi‑stage reciprocating (piston) design with 100% oil‑free compression and oxygen‑safe construction, guaranteeing pure, contamination‑free oxygen output – essential for medical, pharmaceutical, food, and high‑purity industrial applications.

Industrial oxygen cylinder filling – Fills high‑pressure cylinders for welding, cutting, brazing, and metal processing.
Medical oxygen stations – Boosts oxygen from PSA generators, liquid oxygen tanks, or concentrators to cylinder pressure for hospitals, clinics, and homecare.
On‑site oxygen generation (VSA/PSA) – Increases output pressure for storage, bottling, or pipeline distribution.
High‑pressure oxygen storage systems – Charges cascade storage banks up to 30 bar.
Portable and emergency oxygen supply – For field hospitals, disaster relief, high‑altitude facilities, or remote mining camps.
Food & beverage industry – Oxygen enrichment or packaging applications requiring oil‑free, high‑pressure gas.
Oxygen boosting under pressure carries specific safety risks. Our compressor incorporates the following safety features:
Strict degreasing – All components are cleaned and certified for oxygen service (ASTM G93 / ISO 15001).
Anti‑static design – Prevents electrostatic discharge that could ignite oxygen.
Low compression temperature – Multi‑stage design with intercoolers keeps stage discharge temperatures well below limits.
Pressure relief valves – Each stage protected by an ASME/CE certified PRV.
Leak‑tight seals – Special oxygen‑compatible gaskets and O‑rings to prevent leakage.
Optional explosion‑proof motor – Available for hazardous environments (ATEX / IECEx).
Automatic shutdown – On high discharge temperature, high pressure, or low intake pressure.
Oil‑free purity – No lubricating oil in the compression chamber. No oil mist, no carbon deposits.
Medium pressure capability – Up to 30 bar, covering most cylinder filling and industrial gas applications.
Energy efficient – Multi‑stage compression reduces power consumption compared to single‑stage.
Easy to install – Skid‑mounted with vibration dampers; just connect inlet, outlet, and power.
Low noise – Enclosed or open design available; noise level ≤ 75 dB(A) at 1 meter.
Global certifications – CE, ISO 9001, ATEX (on request). Spare parts and technical support worldwide.
