shangrila is equipped with a 15-inch touch-screen. The screen surface is smooth with durable PC material and the user interface is simple, clear and easily monitored and operated. This unit is a synthesis of aesthetics and functionalism. Compared with the older ventilator, this NVP integrates all functioning buttons and knobs in one screen and one navigator wheel knob. All of the settings as well as the monitoring can be displayed in one screen. Such high tech integration provides more convenience for user’s operation and equipment cleaning. A surrounding handle makes it easy for the user to move the ventilator to different angles. Aluminum guide rails at both sides of the ventilator provide varied positions for hanging extension modules.
