The PO3/PO5 is a compact and high-performance portable oxygen concentrator that utilizes advanced molecular sieve technology to efficiently deliver oxygen-enriched air.
Equipped with respiratory-synchronized triggering technology, the device offers high sensitivity and effectively improves oxygen utilization, providing patients with a more comfortable therapy experience. The system automatically switches to a backup continuous oxygen supply mode if no spontaneous breathing is detected for 10 consecutive seconds to ensure patient safety.
The PO3 and PO5 models feature three and five adjustable oxygen flow settings respectively, enabling precise adaptation to varying respiratory demands while maintaining a stable oxygen concentration of 93%±3%. With its lightweight and compact design, this device serves as an ideal medical companion for travel.


The breath-synchronized triggering technology ensures a consistent high oxygen flow, with backup pulse and continuous modes for patient safety in case of no breath detection.

The high-end and replaceable molecular sieve provides oxygen with a concentration of 93±3%.

PO3:The maximun oxygen flow is 660mL/min,and it provodes 3 pluse-dose settings to cater to a wide range of needs.
PO5:The maximun oxygen flow is 1000mL/min,and it provodes 5 pluse-dose settings to cater to a wide range of needs.
