Product Description
PSA Oxygen Generator (Pressure Swing Adsorption Oxygen Generator)
is a portable oxygen supply device based on Pressure Swing
Adsorption (PSA) technology. It rapidly produces medical-grade
oxygen by separating air through molecular sieves. It features core
advantages such as small size, light weight, fast start-up, and low
noise. Without the need for an external oxygen source, it can be
used by simply plugging into a power supply, perfectly adapting to
mobile scenarios such as plateau emergency rescue and outdoor
medical care. As a core type of psa medical oxygen generator, its
flow rate of 50L/min can meet the oxygen demand of multiple people
simultaneously, and the 90% medical-grade purity complies with the
National Standard for Medical Oxygen (GB 8982-2014). It can be
directly used for relieving hypoxia symptoms and emergency support,
making it an essential equipment for medical stations and emergency
vehicles in plateau areas.

I. Why Do Plateau Emergency Rescues Rely on Medical-Grade PSA
Oxygen Generators?
Plateau areas are characterized by high altitude and thin air, with
oxygen partial pressure only 50-70% of that in plain areas. This
easily triggers altitude sickness (such as headaches, chest
tightness, and difficulty breathing), which can lead to
life-threatening conditions like pulmonary edema and cerebral edema
in severe cases. Traditional oxygen cylinders have limited capacity
(usually 10-40L) and short battery life (only 2-4 hours of oxygen
supply for a single person), and they need to be replaced
frequently, failing to meet the needs of long-term emergency rescue
and multi-person oxygen supply. In contrast, the PSA Oxygen
Generator with 50L/min flow rate and 90% purity can continuously
produce medical-grade oxygen. Its 50L/min flow rate can support 3-5
people breathing simultaneously (10-15L/min per person), fully
covering the needs of scenarios such as plateau emergency rescue,
camping, and scientific expeditions.
The 90% medical-grade purity is the core guarantee for emergency
oxygen supply. It can not only quickly relieve altitude sickness
symptoms but also provide life support for critically ill patients,
with oxygen concentration stability far exceeding that of ordinary
household oxygen generators. The device’s portable design (equipped
with rollers) allows for easy transportation to emergency sites.
The dual power supply mode of 220V mains and storage battery adapts
to the unstable power environment in plateau areas, ensuring
continuous oxygen supply even after power outages.
II. Technical Highlights: Special Design for Plateau Environments
Plateau areas have low air pressure and large temperature
differences (-20℃ to 30℃), placing extremely high requirements on
the performance stability of oxygen generation equipment. The PSA
Oxygen Generator has undergone three major optimizations for
plateau environments: first, optimizing adsorption pressure
parameters to adapt to air separation needs under low-pressure
conditions, ensuring stable output of 90% purity oxygen within an
altitude of 5000 meters; second, adopting a wide temperature range
design, where core components can withstand extreme temperature
differences to avoid low-temperature start-up failures; third,
enhancing dustproof and moisture-proof functions to adapt to the
windy and dry climate characteristics of plateaus, extending
equipment service life.
As a miniaturized product of medical oxygen generation plant, the
device is equipped with multiple safety protection functions:
real-time oxygen concentration monitoring (automatic alarm when
below 82%), pressure overload protection, overheating protection,
low battery alarm, etc., ensuring safe use during emergency
rescues. The principle of psa oxygen plant working is simple and
reliable, requiring no professional maintenance—only regular
replacement of filters and molecular sieves. With a low operating
threshold, it is suitable for medical staff at medical stations and
emergency personnel to master quickly.
The PSA Oxygen Generator has become a life-saving equipment for
plateau emergency rescues due to its portability, stability, and
high-purity advantages. The configuration of 50L/min flow rate and
90% medical grade accurately matches the medical needs in plateau
areas. The core technology of its psa medical oxygen plant can
provide continuous and safe oxygen supply support for plateau
regions, making it an indispensable equipment for medical stations,
emergency centers, and outdoor teams.
