Fan
The fan is a centrifugal fan with a precision-balanced fanwheel and a
3-phase motor with Hall effect sensors for continuous speed measure-
ment. The fan is controlled from the mainboard, and the fan speed de-
pends on the current pressure requirements and the current leakage.
1.3.2 WM 100 TH respiratory air humidifier
The heatable respiratory air humidifier functions on the so-called pass-
over principle. The air coming from the therapy device is routed across
the surface of a preheated water reservoir. This increases the relative
humidity and temperature of the air flow.
The humidifier level can be set individually using the buttons on the
therapy device.
The power of the heating element, and consequently the temperature
of the water in the humidifier chamber, is controlled electronically via
the therapy device.
The transparent window of the humidifier chamber makes it possible
to check the water level at any time.
