LONGFIAN has officially launched its new-generation 5L medical oxygen concentrator with FDA clearance, fully complying with US medical device regulations. The product delivers reliable medical oxygen therapy for home patients, primary care clinics and senior care institutions in North America.
As a medical-grade oxygen device, the concentrator meets strict clinical standards. It maintains oxygen concentration above 90%, meeting long-term oxygen therapy requirements for patients with pulmonary fibrosis, COPD and other chronic respiratory illnesses. The adjustable flow rate ranges from 0.5L to 10L per minute, adapting to diverse scenarios from mild daily oxygen support to continuous oxygen supply for severe cases. Equipped with an upgraded cooling system and premium molecular sieves, the machine supports non-stop 24/7 operation all year round. It avoids common drawbacks of conventional oxygen concentrators, such as overheating and oxygen concentration drop after long hours of running.
Great attention has been paid to user experience for home use. The operating sound level is as low as 40dB, similar to soft conversation, so it will not disturb patients or family members during sleep. The matching humidifier bottle is fitted with a 6PSI pressure relief valve. Compared with ordinary humidifier parts, it prevents excessive pressure safely and delivers humidified oxygen gently to reduce nasal dryness caused by oxygen inhalation. With universal casters at the bottom and net weight of only 15kg, the compact machine can be moved easily between bedrooms, living rooms and wards.
Safety is the top priority of medical equipment. A built-in intelligent multi-alarm system monitors working status in real time. It will trigger alerts automatically for power failure, abnormal pressure and low oxygen concentration. Users can be notified promptly to avoid risks caused by interrupted oxygen therapy. Furthermore, the unit is fully compatible with BiPAP ventilators. Combined oxygen and sleep apnea treatment improves therapeutic outcomes, opening more application opportunities in respiratory departments and sleep therapy centers.
For global business partners, LONGFIAN provides flexible OEM & ODM services. Customization covers brand logo, packaging, user interface and partial functional modules. Distributors can launch private-label products to fit various sales channels, including offline medical stores, online marketplaces and group purchases for nursing homes. Power consumption is controlled under 300W. The energy-saving design cuts long-term running costs, and durable molecular sieves help end users reduce maintenance expenses.
LONGFIAN specializes in R&D and manufacturing of oxygen equipment. Its product portfolio covers household, medical, high-altitude and rehabilitation oxygen supply solutions, sold widely around the world with mature medical quality management systems. The newly FDA-cleared 5L oxygen concentrator completes the brand's product lineup for home medical oxygen in North America.
Driven by the aging population, demand for home oxygen therapy keeps rising in North America. The market has strong demand for compliant, stable and safe medical oxygen concentrators. Leveraging its robust supply chain, LONGFIAN offers stable product supply, technical support and after-sales service for regional distributors, clinics and senior care centers in the United States. Moving forward, LONGFIAN will continue to upgrade respiratory medical hardware and develop oxygen therapy products that meet global regulatory standards, protecting respiratory health for users worldwide.
