Smart Support in a Lighter Design
This compact concentrator provides seven adjustable settings without the size of a heavy tank. Intelligent pulse delivery responds to each detected inhale and pauses during exhalation.
If an inhale is not detected, the fixed-frequency backup begins automatically. A removable battery, clear display, and three power options make the device easier to use throughout the day.
High Purity Across Seven Levels
The molecular sieve concentrates oxygen while the filtration system helps clean incoming air. Levels 1–4 provide approximately 90% oxygen purity. Levels 5–7 provide approximately 80% purity as the oxygen output increases.
Power for Plans Away From Home
The removable 6400mAh battery provides approximately 1.5–5 hours per charge. Runtime depends on the selected setting, operating conditions, battery condition, and temperature. A second charged battery can provide up to ten combined hours.
Two Delivery Systems Working Together
PULSE DELIVERY: OXYGEN WITH EACH INHALE
The concentrator detects the start of each inhale and releases an oxygen pulse. Delivery pauses during exhalation. This reduces unnecessary output between breaths and supports longer battery operation.
FIXED-FREQUENCY BACKUP: TIMED DELIVERY WHEN NEEDED
If the system does not detect an inhale, it automatically begins fixed-frequency oxygen delivery. Timed pulses continue at equal intervals until normal breath detection returns.
Seven Settings. Simple Control.
7 adjustable settings provide a wider range of oxygen output in one compact device. Lower levels support lighter output and longer battery time. Higher levels increase delivery but may reduce battery runtime.
Cleaner Air Starts Inside the Device
Audible alerts and a flashing screen help signal changes that need attention. The system monitors temperature, battery power, breathing detection, oxygen concentration, fan operation, and compressor performance while the concentrator is running.

Frequently Asked Questions
Find quick answers about power, placement, filters, cleaning, storage, and troubleshooting.
No. The concentrator pulls in surrounding air and passes it through its filtration and molecular sieve system. Concentrated oxygen is produced while the device operates, so there is no tank to refill or exchange.
Yes. Position the concentrator correctly and keep every intake, vent, and outlet clear. Do not cover the carry case with clothing or place it inside another enclosed bag while the device is running.
Yes. Connect the supplied adapter to a compatible 100–240V wall outlet. Keep the device upright and confirm that its airflow openings remain clear. Check every connection before turning the concentrator on.
Turn off the concentrator and disconnect every power source. Remove the battery, open the filter cover, and replace the used intake filter. Install the new filter correctly before refitting the cover and battery.
Contact the equipment provider when the display reports low oxygen concentration or the concentrator produces unusual pressure or noise. The molecular sieve may need inspection or replacement before the device returns to normal operation.
Store the concentrator and battery in a clean, dry place with a stable temperature. Avoid direct sunlight, freezing conditions, strong heat, and moisture. Humid storage may shorten the molecular sieve’s working life.
Move the concentrator to a cooler and better-ventilated area. Check every intake, vent, and outlet for blockages. Let the device cool before restarting it. Contact the equipment provider if the warning appears again.
