* The AS100A Auto CPAP intelligently adjusts treatment pressure by tracking airway resistance from different body positions and sleep stages, supporting both CPAP and Auto CPAP modes to prevent apnea Core Features * Modes & Pressure Range: CPAP and Auto CPAP, pressure 4–20 cmH₂O (0.5 cmH₂O increments), single-fault safe up to ≤30 cmH₂O; ramp time adjustable 0–60 min Expiratory Pressure Relief (AS‑Elex): 7 levels of pressure decrease during exhalation for comfort * Central Apnea Detection: Identifies and distinguishes central apnea events to prevent inappropriate pressure increases * AS‑Dry Technology: After therapy, blower runs at lower speed to dry tube and mask, reducing moisture and bacterial growth Leak Compensation, Auto On/Off, Manual Pressure Titration support * Mask Leak Test, Altitude Compensation, Data Alerts for power, filter change, leakage and more Humidification & Filtration * Heated humidifier (300 mL) with 6 (or 5 in some sources) adjustable levels * Optional HEPA/PM2.5 filter (~20 cm²) to clean incoming air and protect the device Display & Data * 3.5″ color touchscreen, supports English and Chinese * SD card storage: Records up to 5 years of therapy data; ≥8 GB recommended; data includes P90, AHI, SNI, leak, average pressure, treatment time, and fault logs Physical & Power Specs * Dimensions: * Without humidifier: 160 × 148 × 99.5 mm *With humidifier: 247 × 148 × 99.5 mm * Weight: ~0.82–0.88 kg without humidifier; ~1.26–1.36 kg with humidifier * Power: AC 100–240 V, 50/60 Hz, max 2 A; DC output 24 V * Protection & Noises: Class II, BF-applied part, IP22-rated; noise ≤28 dBA (power), sound power ≤38 dBA at 10 hPa Pressure & Measurement Accuracy * Pressure accuracy: ±0.5 hPa (static variation at 10 hPa); stability ±1 hPa across 4–20 hPa * Flow accuracy: ±2% or 0.05 L/min; * Pressure measurement uncertainty: ±(0.1 hPa +1.5%) Tube Specs & Environment * Tube: 1.8 m long × 19 mm inner diameter Tube: 1.8 m long × 19 mm inner diameter * Operation: 5–35 °C, 10–93% non-condensing humidity, 760–1060 hPa pressure Transport/storage: –20–60 °C, same humidity tolerances, 500–1060 hPa
