The blower is designed for use in closed systems. Its function is to generate
the pressure required for ventilation. In order to improve the mix of gases in
the system the blower generates a circulatory flow.
The blower is based on the radial principle, and is regulated according to
requirement by an electronic activation circuit. In operation the maximum
ventilation pressure is 50 mbar. The control variables used are the measured
values from the pressure and flow sensors contained in the breathing system.
The ventilation pressure and the circulatory flow during inhalation and exhala-
tion are attained by means of defined activation of the blower (21) and the
flow valve (6) in the breathing system
the manual breathing bag (27).
