MedO – Medical Oxygen Generator for Hospitals & Healthcare Facilities
Absstem’s MedO Medical Oxygen Generator is a PSA-based on-site oxygen generation system designed to provide medical-grade oxygen for hospitals, clinics, and healthcare institutions without dependence on cylinders or liquid oxygen supply.
MedO systems deliver 93–96% oxygen purity, compliant with global pharmacopeia standards, ensuring safe and continuous oxygen supply for ICUs, operation theatres, emergency wards, and central pipeline systems.
From small community hospitals to 1,000+ bed multi-specialty hospitals, MedO is engineered for round-the-clock reliability, patient safety, and long-term cost savings.
What is a Medical Oxygen Generator?
A medical oxygen generator is a PSA-based system that produces medical-grade oxygen on-site from atmospheric air.
It replaces cylinders and liquid oxygen by delivering continuous, hospital-grade oxygen directly into the medical gas pipeline network.
MedO is Absstem’s hospital-grade PSA medical oxygen generator, built for 24×7 critical care environments.
How PSA Medical Oxygen Generator Works
Air Intake & Purification
Ambient air is filtered, dried, and compressed to remove moisture, oil, and particulates.
PSA Oxygen Separation
Zeolite molecular sieves remove nitrogen, allowing medical-grade oxygen to pass through.
Oxygen Storage & Distribution
Oxygen is stored in buffer tanks and supplied to the MGPS (Medical Gas Pipeline System)
Automated Control
PLC-based automation with IIoT monitoring ensures stable purity, pressure, and continuous supply.

FAQs – MedO (Medical Oxygen Generator)
What is the difference between a PSA generator and a PSA plant?
There is no technical difference between a PSA generator and a PSA plant. Both use PSA technology to generate oxygen on-site from atmospheric air. The term generator refers to the core separation unit, while plant means the complete on-site system with compressors, storage, controls, installation, and commissioning. At Absstem, every PSA generator is delivered as a fully installed PSA plant.
What is a medical oxygen generator?
A medical oxygen generator is a PSA-based system that produces medical-grade oxygen on-site from atmospheric air. It supplies continuous oxygen directly into a hospital’s medical gas pipeline system, eliminating dependence on cylinders or liquid oxygen.
How does a PSA medical oxygen generator work?
A PSA medical oxygen generator produces oxygen on-site from atmospheric air. Ambient air is filtered, dried, and compressed, after which PSA molecular sieves remove nitrogen and allow medical-grade oxygen to pass through. The oxygen is stored and supplied directly to the hospital’s medical gas pipeline system with automated purity and pressure control.
Is oxygen produced by MedO safe for patient use?
Yes. MedO produces medical-grade oxygen with 93–96% purity, compliant with international and Indian pharmacopeia standards. It is designed for safe use in ICUs, operation theatres, emergency wards, and other critical care areas.
Can MedO replace oxygen cylinders completely in hospitals?
Yes. MedO is designed to act as the primary oxygen source for hospitals. It eliminates cylinder refilling delays, storage risks, and supply chain disruptions while ensuring uninterrupted 24×7 oxygen availability.
How do hospitals select the right MedO capacity?
MedO capacity is determined based on hospital bed count, oxygen pipeline load, ICU and OT demand, and peak usage patterns. Absstem’s engineers evaluate these parameters and design a customised system to ensure stable purity, pressure, and long-term reliability.
