for home usehome carecompact

Overview
Dawei's 1 L/min portable oxygen concentrator (models ZY-1JW and ZY-1S) is designed for medical oxygen therapy in home and mobile settings. It integrates oxygen delivery and an internal nebulization option, offers adjustable flow and timer functions, quiet operation, digital controls with voice prompts and infrared remote, and built-in safety protections for clinical and home-care use.

Features

• Oxygen purity: ≥90% (ZY-1JW) or 93% ±3% (ZY-1S).
• Integrated nebulizer: supports aerosol therapy without separate device.
• Flow rate: 1 L/min (adjustable; some configurations provide up to 7 discrete levels).
• Timer: 30-minute increments up to 4 hours, plus continuous mode.
• Low noise: <60 dB for patient comfort in residential environments.
• Portable design: approximately 6 kg, compact footprint for transport and travel.
• User interface: digital display, voice broadcast, and infrared remote for simplified operation.
