Dual Flow Oxygen Concentrator – ToronOC™ 10L-D
Dual-Flow 10 L/min Medical Oxygen Concentrator for Home and Clinical Use
ToronOC™ 10L-D oxygen concentrator is a dual-flow medical oxygen system that delivers up to 10 liters per minute of medical-grade oxygen, splittable across two independent patient outlets. The device supports two patients simultaneously or a single patient at high-flow rates, making it well suited for clinics, nursing homes, and household settings with multiple users.
The ToronOC™ 10L-D oxygen concentrator produces oxygen at 93% (±3%) concentration through pressure swing adsorption, drawing source gas directly from ambient room air. Two front-panel flowmeters and humidifier bottles allow each outlet to be set independently between 0.5 and 5 L/min, or combined into a single high-flow output of up to 10 L/min.
Designed for continuous 24/7/365 operation, the home oxygen concentrator runs from a standard wall outlet and incorporates innovative cooling technology that protects the compressor and molecular sieve through extended duty cycles. A clear LCD display, four-direction casters, and an integrated alarm package keep the unit straightforward to operate, monitor, and reposition.
The dual-outlet architecture makes the ToronOC™ 10L-D oxygen concentrator machine practical for shared therapy rooms, dual-bed home care arrangements, and clinical settings where one device must serve two patients on different prescriptions, lowering total equipment cost and simplifying inventory management.

Theory and Method
The ToronOC™ 10L-D oxygen concentrator generates medical-grade oxygen through pressure swing adsorption (PSA), the established separation method for producing enriched oxygen from atmospheric air. Ambient air contains roughly 78% nitrogen and 21% oxygen; the PSA cycle isolates the oxygen fraction while venting nitrogen back to the surrounding environment.
An oil-less compressor pressurizes filtered room air and feeds it into a column packed with zeolite molecular sieve. The sieve preferentially adsorbs nitrogen at elevated pressure, allowing oxygen-enriched gas to pass through to a product reservoir. A second column desorbs the captured nitrogen at lower pressure, regenerating the sieve for the next adsorption cycle.
Two columns alternate continuously between adsorption and regeneration to produce a steady output of oxygen at 93% (±3%) concentration. The product gas then flows into a manifold that splits into two independent outlets, each with its own flow regulator and humidifier bottle. Each outlet may be set anywhere from 0.5 to 5 L/min, with a combined maximum of 10 L/min across both lines.
Front-panel flowmeters provide direct visual confirmation of delivered flow on each outlet. Both humidifier bottles include a 6 PSI pressure relief valve that protects the patient circuits from over-pressurization in case downstream tubing becomes blocked.
Onboard sensors monitor oxygen concentration, output flow, internal pressure, and temperature continuously. Audible and visual alarms activate if mains power fails, output flow drops below the prescribed setting, oxygen concentration falls out of specification, or internal temperature exceeds the safe operating envelope, protecting both patients and the 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 both humidifier bottles with distilled water between the minimum and maximum lines, then secure each to its outlet port. The 6 PSI pressure relief design protects each patient circuit if downstream tubing becomes blocked.
- Cannula Connection — Attach a nasal cannula or supply tube to each humidifier outlet. Either outlet may be used independently, or both may be connected to a single patient circuit for high-flow delivery.
- 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 rates.
- Flow Adjustment — Set the prescribed flow rate on each outlet using its flow control knob, reading the value from the calibrated flowmeter. Each outlet adjusts independently from 0.5 to 5 L/min, with a total combined output of up to 10 L/min.
- Operation and Monitoring — Monitor the LCD for treatment time, flow status, and any active alarms during therapy. The audible alarms for power failure, high or low pressure, low oxygen concentration, low flow, and high temperature alert the user to any deviation from the prescribed setpoint.
- Shutdown and Maintenance — After therapy, switch off the unit, disconnect both cannulas, and empty the humidifier bottles. Clean the external air filter on the schedule defined in the user manual to maintain output purity and airflow.
