Portable Oxygen Concentrator MDLZY41
Advanced portable oxygen concentrator delivering adjustable oxygen concentration from 30–90% with quiet, efficient operation. Lightweight at 8.0 kg with intuitive HD LCD touch screen control, infrared remote capability, and integrated negative ion generation for enhanced therapeutic delivery in clinical and home care settings.




Clinical overview
The MDLZY41 Portable Oxygen Concentrator is engineered for reliable oxygen delivery across clinical and home care environments. Utilising Pressure Swing Adsorption (PSA) technology, it generates oxygen on-demand with adjustable concentration from 30–90% (±3%), accommodating diverse patient requirements and clinical protocols. The device operates at ≤45 dB(A), ensuring minimal acoustic disturbance in patient care areas and residential settings.
Weighing only 8.0 kg with compact dimensions (404 × 182 × 383 mm), the MDLZY41 enables patient mobility and flexible deployment. The integrated negative ion generation function (6 million/cm³) enhances therapeutic efficacy, while dual inhalation methods—ear-hanging oxygen and nasal cannula—support varied patient preferences and clinical workflows. Infrared remote control, pre-set timer function (up to 180 minutes), and automatic power-off protection ensure safe, user-friendly operation.
