Stable 5L High-Concentration Oxygen Delivery
Adjustable from 1 to 5 L/min, the concentrator is designed to maintain high oxygen concentration throughout its operating range.
At a flow rate of 5 L/min, oxygen concentration remains approximately 93±3%, providing a stable oxygen source for users who require higher-flow supplementation.
Dual-User Oxygen & Nebulization Functions
The system supports a dual-user oxygen setup with the appropriate connector, making it possible for two users to receive oxygen from one machine.
A separate nebulization outlet also allows the unit to be used with the supplied nebulizer kit for convenient at-home respiratory care.
Built for Longer Daily Operation
A powerful compressor, dual molecular sieve tanks, and multiple filtration stages support stable oxygen production during extended use.
The machine is designed for continuous operation and includes dedicated air intake and cooling structures for heat management.
Easy to Move Around the Home
With integrated side handles and four universal caster wheels, the concentrator can be moved between the bedroom, living room, or other indoor spaces without lifting the entire unit.

Before You Use
For safe and reliable operation:
- Use the oxygen flow rate recommended by a qualified healthcare professional when oxygen therapy is medically required.
- Do not adjust a prescribed oxygen flow setting without professional guidance.
- Place the machine on a stable surface with sufficient clearance around the air inlet and cooling vents.
- Keep the concentrator away from smoking, flames, candles, sparks, heaters, and other ignition sources.
- Check the oxygen tubing, humidifying cup, nebulizer accessories, filters, and connections before each use.
- Add water to the humidifying cup only according to the specified water level and instructions.
- Use the nebulization function only with compatible accessories and medications as directed by a healthcare professional.
- When two users are connected, confirm that the total flow configuration is appropriate for both users.
- Do not cover the machine or block the air inlet and exhaust vents during operation.
- If an oxygen concentration, flow, pressure, or voltage alarm appears, check the machine before continuing use.
- Read the supplied instruction manual before first use.
