The following summary describes the functions of the various principal components rather than
giving a detailed description of the components themselves.
The blower draws ambient air through an ambient air filter F1 into a mixing chamber. The blower
compresses the gas to a positive pressure of max. 140 mbar at a flow rate of up to 180 L/mi
blower is run at constant rotation speed - that is, the speed is not varied in the course of a
The inspiratory pressure is regulated by means of the bypass valve. The combination of the blower
and the bypass valve function thus represents a pressure source.
On the inlet and outlet sides of the blower there are mufflers SD1 and SD2, which reduce the
sound level of the blower.
