oil free piston oxygen compressor for for cylinder filling

The compressor has a completely oil-free design, which avoids oil contamination of oxygen and ensures the purity of the gas. It is suitable for small hospitals, laboratories, and some small oxygen filling systems, providing efficient and stable oxygen compression service.

Features of Oil Free Piston Oxygen Compressor

1. Four-stage compression system: Adopts a four-stage compression design, with each stage equipped with a safety valve to ensure safety and stability throughout the compression process. Each stage also has a temperature sensor for real-time monitoring, enabling timely alarm and shutdown protection if the temperature exceeds safe limits.
2. Completely oil-free design: No oil lubricant is used, preventing oil contamination of oxygen and guaranteeing the purity required for medical, food, and other high-purity gas industries.
3. Efficient Compression and Reliable Performance: The four-stage system provides high-pressure output, handling input/output pressures from 3–4 bar (40–60 psig) to 150 bar (2150 psig). Suitable for small PSA oxygen systems and stable 24-hour operation for hospitals and communities.
4. Compact design: Small size, light weight, and equipped with a forklift slot for easy movement and installation, ideal for limited spaces.
5. Safety guarantee mechanism: Features low inlet pressure protection at the intake and high exhaust pressure protection at the outlet, ensuring automatic shutdown under abnormal conditions to prevent equipment damage.
6. Brand motor selection: Options for well-known brands such as Siemens and ABB ensure reliability and long-term stable operation.
7. Low noise operation: Compressor noise is less than 75dB, suitable for medical environments, minimizing disturbance to patients and staff.

The Working Principle of Oil Free Piston Oxygen Compressor

The compressor realizes oxygen pressurization through the reciprocating movement of a piston inside a cylinder. Low-pressure oxygen enters the compression chamber from the inlet, and the piston compresses the gas to a higher pressure by moving forward. In a four-stage system, oxygen passes through four successive compression stages, each increasing the pressure further. After each stage, the gas is cooled to prevent overheating, ensuring stable operation. Each stage is equipped with temperature and pressure sensors for real-time monitoring, and the system will automatically alarm and shut down if values exceed safety ranges.

Application Areas of Oil Free Piston Oxygen Compressor

1. Medical field: Ideal for small hospitals, clinics, and emergency vehicles, providing stable oxygen for wards and operating rooms. Oil-free and low-noise design ensures medical-grade purity and minimal disturbance.
2. Oxygen Cylinder Filling: Capable of providing high-pressure oxygen for cylinder filling, suitable for oxygen supply, welding, and cutting operations. Can fill cylinders with 93% pure oxygen.
3. PSA Oxygen Generation System: Functions as a booster in PSA systems to maintain normal operation, supplying 7–10 kg of pipeline pressure for stable hospital oxygen supply.
4. VPSA Oxygen Source Pressurization: Suitable for VPSA systems, ensuring continuous and high-purity gas supply through stable compression.
5. Small community and laboratory: Provides convenient oxygen filling and storage solutions for community medical facilities and research laboratories, ensuring stable and pure oxygen supply.
6. Emergency Rescue: Offers easy mobility and stable performance for use in disaster area rescue and field medical treatment.
