oil free reciprocating oxygen compressor for small hospitals

This oxygen compressor adopts a totally oil-free design to ensure gas purity without oil contamination, and is capable of stable operation for a long time in a low-noise, low-maintenance environment. It is suitable for small hospitals or places that require flexible deployment, offering high efficiency, reliability, and economy.

Features of Oil Free Reciprocating Oxygen Compressor

1. All oil-free design: Uses oil-free compression principle to avoid oil contamination, ensuring oxygen purity for strict medical requirements.
2. Two-stage compression: Increases oxygen pressure through a two-stage system, adapting to working pressure ranges from 3–4barg up to 150barg, providing stable compression.
3. High reliability: Equipped with a stainless steel cylinder for enhanced durability and corrosion resistance. Temperature and pressure over-limit protection for safe operation in high temperature and pressure environments.
4. Low-noise operation: Noise less than 75dB, suitable for quiet medical environments and reducing work interference.
5. Compact design: Small size, light weight, and equipped with casters for easy movement—ideal for small hospitals or mobile medical equipment.
6. Long service life: Low-speed operation; piston ring life up to 4,000 hours in low-pressure, and 1,500–2,000 hours in high-pressure environments, reducing replacement frequency.
7. EU CE certification: Meets EU quality and safety standards, suitable for international markets.
8. Customized solutions: Can be tailored to customer requirements for different working conditions.
9. High efficiency and energy saving: Low speed (260–400 rpm) ensures low energy consumption and extends equipment life.

The Working Principle of Oil Free Reciprocating Oxygen Compressor

The compressor relies on the reciprocating motion of a piston. Oxygen enters the compression chamber from the suction end and is compressed as the piston moves. After two stages, oxygen pressure is gradually increased to the set discharge pressure. The oil-free design eliminates oil lubricants, avoiding gas contamination and ensuring oxygen purity.
During operation, internal temperature and pressure switches monitor unit status. If either exceeds safe limits, the system alarms and stops to prevent overload, ensuring long-term stable operation and oxygen quality.

Application Fields of Oil Free Reciprocating Oxygen Compressor

1. Medical field: Widely used in small hospitals, clinics, and emergency vehicles to provide high-purity oxygen, especially for therapy and first aid. Low noise design is ideal for medical environments.
2. Industrial oxygen supply: Suitable for continuous industrial oxygen supply in metallurgy, chemistry, welding, and metal processing. Ensures stable oxygen for production needs.
3. VPSA, PSA oxygen production: Used as a booster in VPSA (Vacuum Pressure Suction Adsorption) and PSA (Pressure Swing Adsorption) systems to improve gas purity and stabilize supply.
4. Laboratory and scientific research: Supplies high purity oxygen for labs and research facilities, including gas analysis, chemical experiments, and biological research.
5. Emergency rescue: Suitable for mobile and flexible emergency medical equipment, disaster relief, and field medical sites, providing reliable oxygen supply for personnel safety.
6. Environmental protection: Provides stable oxygen supply for sewage treatment, exhaust gas purification, and other environmental applications to improve environmental quality.
