High Flow Oxygen Concentrator – ToronOC™ 10L-S
10 L/min High-Flow Medical Oxygen Concentrator for Home and Clinical Use
ToronOC™ 10L-S oxygen concentrator is a high-flow, single-outlet medical oxygen device that delivers up to 10 liters per minute of medical-grade oxygen for patients on demanding therapy regimens. The unit covers a continuous flow range from 0.5 to 10 L/min at 93% (±3%) oxygen concentration, supporting both routine and elevated-flow respiratory care.
The ToronOC™ 10L-S oxygen concentrator concentrates oxygen from ambient room air using molecular sieve pressure swing adsorption, eliminating cylinder logistics and refill scheduling. The device runs from a standard wall outlet, making it equally suitable as a home oxygen concentrator, a clinic bedside unit, or a backup supply during cylinder transitions.
Innovative cooling technology supports continuous 24/7/365 operation without forced rest periods, which matters for patients on long-term high-flow oxygen therapy. A clear LCD display shows operating status and active alarms, while four-direction casters allow the unit to be moved easily between bedrooms, living rooms, and treatment areas.
The integrated humidifier with 6 PSI pressure relief, single calibrated flowmeter, and comprehensive alarm package keep the oxygen concentrator machine straightforward for patients and caregivers to operate safely. The 10 L/min capacity makes the ToronOC™ 10L-S well suited for high-flow nasal cannula (HFNC) therapy, hyperbaric chamber inlets, and severe respiratory cases requiring elevated oxygen delivery.

Theory and Method
The ToronOC™ 10L-S oxygen concentrator produces medical-grade oxygen using pressure swing adsorption (PSA), the established method for separating oxygen from atmospheric air. Ambient room air contains roughly 78% nitrogen and 21% oxygen; the PSA cycle isolates the oxygen fraction and discharges nitrogen back to the surrounding environment.
Inside the concentrator, an oil-less compressor pressurizes filtered room air and feeds it into a column packed with zeolite molecular sieve. The zeolite preferentially adsorbs nitrogen at elevated pressure, allowing oxygen-enriched gas to pass through to a product reservoir. A second column then desorbs the captured nitrogen at lower pressure, regenerating the sieve for the next cycle.
The two columns alternate continuously between adsorption and regeneration to produce a steady output of oxygen at 93% (±3%) concentration. The cycle is sized for a 10 L/min capacity, allowing the oxygen concentrator to maintain stable purity even at the high end of the flow range where lower-capacity units typically lose concentration.
The product gas passes through a single flow regulator and then through the humidifier bottle, where a 6 PSI pressure relief valve protects the patient circuit from over-pressurization. A calibrated flowmeter on the front panel provides direct visual confirmation of delivered flow, while the LCD displays operating status, accumulated treatment time, and any active alarms.
Onboard sensors monitor oxygen concentration, output flow, internal pressure, and temperature throughout each cycle. If any parameter falls outside the safe envelope — power loss, low oxygen purity, abnormal pressure, or elevated internal temperature — the concentrator triggers an audible and visual alarm and adjusts the cycle to protect both patient and device.
Operating Method Steps
- Site Preparation — Place the oxygen concentrator on a flat, stable surface in a well-ventilated area, clear of curtains, walls, and heat sources by at least 30 cm. Confirm that the rear air intake and side exhaust vents are unobstructed.
- Humidifier Setup — Fill the humidifier bottle with distilled water between the minimum and maximum lines, then secure it to the outlet port. The 6 PSI pressure relief design protects the patient circuit if downstream tubing becomes blocked.
- Cannula Connection — Attach the nasal cannula or supply tubing to the humidifier outlet. For HFNC or HBOC integration, route the supply line to the connected device per its operating instructions.
- Power-On and Self-Test — Connect the unit to a grounded mains outlet and switch it on. The LCD displays the boot sequence and the oxygen concentrator runs an internal self-test before delivering oxygen at the default flow rate.
- Flow Adjustment — Set the prescribed flow rate using the flow control knob, reading the value from the calibrated flowmeter. The flow can be adjusted continuously from 0.5 to 10 L/min.
- Operation and Monitoring — Monitor the LCD for treatment time, flow status, and any active alarms during therapy. The audible alarm package alerts the user to any deviation from the prescribed setpoint, including power failure, abnormal pressure, and low oxygen concentration.
- Shutdown and Maintenance — After therapy, switch off the unit, disconnect the cannula, and empty the humidifier bottle. Clean the external air filter on the schedule defined in the user manual to maintain output purity and airflow.
