PSA O2 Generator (Pressure Swing Adsorption Oxygen Generator) is a portable oxygen supply device designed for home medical scenarios. Based on pressure swing adsorption technology, it separates air through medical-grade molecular sieves and can continuously produce medical-grade oxygen (90% purity) at 8L/min. It features core advantages of compact size, light weight, low noise, and simple operation. No external oxygen source is required – it can be used by plugging into a power supply, perfectly meeting the long-term home oxygen therapy needs of COPD patients. As a mainstream model of psa medical oxygen generator, it can effectively relieve hypoxia symptoms (e.g., shortness of breath, chest tightness, difficulty breathing) in COPD patients, improve quality of life, and serve as an ideal choice for home medical oxygen supply.

COPD (Chronic Obstructive Pulmonary Disease) is a chronic respiratory disease. Patients suffer from impaired lung function and often experience hypoxia symptoms. Long-term home oxygen therapy is crucial for improving prognosis and quality of life. Traditional oxygen cylinders have pain points of short battery life, inconvenient transportation, and high costs. The 8L/min flow rate of the PSA O2 Generator can meet the medium-to-high intensity oxygen inhalation needs of COPD patients (3-5L/min for daily oxygen therapy, 6-8L/min during activities). The 90% medical-grade purity ensures the effectiveness of oxygen therapy, effectively alleviating cardiopulmonary function damage caused by hypoxia.
As a miniaturized product of medical oxygen generation plant, it has extremely low operating costs. Running for 12 hours a day only consumes 1-2 kWh of electricity, with an annual electricity fee of less than 500 RMB – far lower than bottled oxygen (about 1000 RMB per month for procurement), significantly reducing patients’ long-term treatment costs. Its silent design (≤45dB (A)) will not affect the rest of patients and their families. Its portability (weight about 8kg) allows use in different scenarios such as living rooms, bedrooms, and balconies. It can even be used for outdoor trips with a vehicle-mounted power supply, completely breaking the scenario limitations of traditional oxygen therapy.
Scientific maintenance can extend the service life of the PSA O2 Generator to more than 5 years. Firstly, the maintenance of the air intake filter is crucial – it needs to be cleaned once a week (rinsed with clean water and dried) and replaced once a month to avoid dust blockage affecting air intake volume and molecular sieve life. Secondly, the molecular sieve is a core component – avoid long-term idleness of the equipment (if not used for more than 1 month, start it up for 30 minutes every month) to prevent moisture and failure of the molecular sieve. Its normal service life is 2-3 years, and medical-grade molecular sieves must be replaced in a timely manner when expired to ensure oxygen concentration meets standards.
Regularly wipe the equipment surface with a clean damp cloth to avoid dust accumulation; do not use corrosive cleaning agents. Properly store the power adapter to prevent falling or moisture, and disconnect the power supply when not in use for a long time. In addition, it is recommended to contact professional personnel from psa oxygen generator manufacturers for a comprehensive inspection every year to test oxygen concentration, fan performance, control system, etc., and promptly identify and address potential issues. Reasonable maintenance can not only extend equipment life but also ensure the stability of oxygen therapy effects, safeguarding the health of COPD patients.
With its advantages of compliance, efficiency, portability, and cost-effectiveness, the PSA O2 Generator has become the preferred equipment for home oxygen therapy for COPD patients. The 8L/min flow rate accurately matches patients’ oxygen inhalation needs. Its psa medical oxygen plant technology can provide continuous and safe oxygen therapy support for COPD patients. Combined with correct use and scientific maintenance, it can help patients improve quality of life and reduce family burdens.
