Adjustable pressure from 4 to 20 cmH2O (inspiratory and expiratory range) to accommodate a wide range of therapeutic requirements.

The device features a color display (3.5-inch according to specifications) for monitoring and adjusting settings.

6. Is the DF-20A-HM portable for travel?

The unit is compact and lightweight (1.7 kg; dimensions 266.8 × 172.5 × 118.5 mm), making it convenient to carry and store. Note: it has no internal battery and requires mains power; check airline policies and available power outlets for in-flight use.

Check that the mask is properly fitted, tubing is connected and not kinked, the humidifier/water chamber is correctly seated, and the device is receiving power. If the alarm persists or you experience continued apneas or breathing difficulties, stop use and consult your healthcare provider or the device supplier for troubleshooting and service.
