France-Imported Molecular Sieve and Lightweight PSA Oxygen Concentration
The Konsung KSN-5 Elite (VM-OC5L) is a 5-litre oxygen concentrator built around advanced PSA (pressure swing adsorption) technology incorporating a France-imported molecular sieve — a material quality specification that directly affects adsorption efficiency, oxygen purity consistency, and sieve longevity over the unit’s service life. The concentrator delivers 93±3% oxygen purity across a flow range of 1–5L/min at an output pressure of 30–70kPa, meeting the medical oxygen purity specifications required for long-term oxygen therapy in COPD, chronic respiratory failure, heart failure-related hypoxaemia, and other conditions requiring continuous supplemental oxygen. At 14.5kg and 350×340×475mm, the KSN-5 Elite is notably compact and lighter than many comparable 5-litre concentrators, making it well-suited to home care environments where manageable weight and a small footprint are practical priorities alongside clinical performance.
Integrated Nebulizer and Comprehensive Seven-Function Alarm System
The KSN-5 Elite is equipped with an integrated nebulizer function that uses the concentrator’s oxygen output to atomise prescribed medication at ≥0.2mL/min — enabling concurrent oxygen-driven bronchodilator or mucolytic nebulisation alongside continuous oxygen delivery. This eliminates the need for a separate nebuliser unit during respiratory therapy. The unit’s alarm system covers seven conditions: power failure, high pressure, low pressure, overheat, overload (with 250V AC / 3A protector), error code indication on the display, and an oxygen purity alarm that alerts when delivered oxygen concentration falls below the therapeutic threshold. The inclusion of a dedicated oxygen purity alarm is a clinically significant safety feature, providing assurance that the molecular sieve is performing within specification during long-term continuous therapy, and alerting caregivers when purity drops to levels that may be inadequate for the patient’s prescribed therapy.
Timing Function, Continuous Operation, and Clinical Classification
The KSN-5 Elite includes a timing system and time-setting function, supporting prescribed session-based oxygen therapy where clinicians or home care protocols specify duration of oxygen delivery. The unit is rated for continuous operation, classifying it as appropriate for uninterrupted 24-hour use required in long-term oxygen therapy prescriptions. As a Class II, BF-type medical device, it meets the electrical safety classification standards for equipment intended to be in contact with or in close proximity to patients. Running at 350W on AC220V/50Hz — compatible with South African mains supply — the KSN-5 Elite is suited to home oxygen therapy patients, frail care facilities, and outpatient respiratory clinics requiring a lightweight, clinically equipped 5-litre concentrator with nebulizer capability and comprehensive alarm monitoring. Available in South Africa from Vital Medical.
