Three Modes. More Control.
Choose how the concentrator delivers oxygen across eight settings. Pulse Dose responds to each inhalation. Constant Flow provides 17 oxygen bursts per minute, with output up to 1,200 mL/min. Level 8 adds uninterrupted Continuous Flow at up to 2,000 mL/min.
Consistent Oxygen Purity
Surrounding air passes through multiple filters before reaching the molecular sieve, where nitrogen is separated from oxygen. The concentrated oxygen then moves through the outlet for delivery, providing 90% ±3% oxygen purity across all eight settings and three delivery modes.
Advanced Filtration. Cleaner Air.
The concentrator draws in surrounding air and passes it through multiple filtration stages that help clean it before concentration. The filtered air then reaches the molecular sieve, where nitrogen is separated before concentrated oxygen moves through the outlet for delivery.
Reliable at Higher Altitudes
Designed to operate at elevations up to 5,000 metres, the concentrator supports dependable use in high-altitude locations. Whether you are travelling through the mountains or living at elevation, it helps maintain stable oxygen output within the manufacturer’s stated operating conditions.
Output at Every Level
Each setting increases oxygen output in clear steps. Levels 1–6 range from 200 to 1,200 mL/min. Level 7 provides 1,200 mL/min at a constant frequency, while Level 8 delivers continuous flow at up to 2,000 mL/min.
Choose Your Power Source
Connect the concentrator to a standard wall outlet at home, use the 12V DC adapter inside a vehicle, or run it from the rechargeable battery. These three power options support use when moving between home, car, and outdoor locations.

Frequently Asked Questions(FAQs)
What does “1–8L” mean?
“1–8L” refers to the device’s eight adjustable settings, not an oxygen output of eight litres per minute. Actual output ranges from 200 mL/min at Level 1 to 2,000 mL/min at Level 8.
How do the three delivery modes differ?
Pulse Dose responds when you inhale. Constant Flow provides 17 oxygen bursts per minute at a steady frequency. Continuous Flow runs without interruption and is available at Level 8, with output reaching up to 2,000 mL/min.
What oxygen purity does it provide?
The concentrator provides 90% ±3% oxygen purity across all eight settings and three delivery modes. Surrounding air passes through multiple filters and a molecular sieve before concentrated oxygen moves through the outlet and into the nasal cannula.
How long does the battery last?
Battery runtime varies by setting and delivery mode. 18-cell battery provides approximately 10-12 hours in Pulse Dose and about 9 to 12 hours in Continuous Flow. Battery condition and temperature can also affect runtime.
How long does charging take?
A full battery charge takes approximately four hours. Charging time may change with battery age, temperature, and remaining power. Charge the battery before longer use and follow the supplied manual for connection and charging instructions.
How should the concentrator and battery be stored?
Store the concentrator and battery in a clean, dry place. Keep it away from direct sunlight, strong heat, and freezing temperatures. Remove dust from the vents, protect the oxygen outlet, and recharge the battery before extended use.
Can it use wall and vehicle power?
Yes. The concentrator accepts 100–240V AC wall power and 12V DC vehicle power. It can also run from its rechargeable battery. Use the supplied adapters and keep the device secure with its air openings unobstructed.
How should the filters be maintained?
Keep the air intake, vents, and exterior free from dust. Inspect the filters regularly and replace them according to the supplied manual. Five replacement filters are included. Never wash or reuse a filter.
Can it operate at higher elevations?
The concentrator is designed to operate from sea level up to 5,000 metres. Performance may depend on local conditions and the selected setting.
Can the battery be replaced during longer trips?
Yes. The rechargeable battery is removable and can be exchanged for a charged replacement. Turn off the concentrator before removing it, follow the supplied instructions, and use only a battery made for this specific model.
