Medical Molecular Sieve Oxygen Generator

Feed air pretreatment for clean inlet air

• Compression is performed by medical-grade air compressors at 0.6-0.8MPa to meet separation requirements.
• Purification removes dust particles ≤1μm through precision filters, reduces dew point to ≤-40°C via refrigerated drying, and limits oil residue to ≤0.1mg/m³ through oil-water separation, meeting medical cleanliness standards.
• PSA adsorption separation serves as the core oxygen purification process.
• Dual or multi-tower operation uses medical-grade zeolite molecular sieve to preferentially adsorb nitrogen and carbon dioxide. PLC-controlled adsorption and regeneration cycles operate at 1-2 minutes per cycle.
• Continuous oxygen production maintains oxygen purity at 93%±2% during adsorption while regeneration releases impurities without supply interruption.
• Oxygen post-treatment ensures compliance with medical oxygen standards.
• Optional secondary PSA purification produces oxygen purity above 99.5%.
• Medical-grade 0.22μm sterilizing filters remove microorganisms. Pressure regulation maintains outlet pressure at 0.1-0.5MPa to match terminal requirements.
• Monitoring and safety functions enable effective risk control.
• Online monitoring tracks oxygen purity, pressure, and flow rate. Audible and visual alarms activate under abnormal conditions such as oxygen purity below 90%.
• Emergency oxygen storage tanks or manifolds enable automatic switchover during unexpected events to ensure uninterrupted oxygen supply.
• Medical performance advantages support safe and efficient clinical operation.
• Safety relies on physical separation without harmful substances and low operating pressure of 0.6-0.8MPa, offering improved safety compared with high-pressure cylinders.
• Efficiency supports qualified oxygen output within 30 minutes and oxygen purity up to 99.5% within 45 minutes, suitable for emergency and surgical applications.
• Energy consumption remains low under ambient temperature operation, approximately 60%-70% of conventional liquid oxygen equipment, with one-button start and unattended operation support.
