draws in fresh breatheable air with his or her
own force. The exhaled air passes through exhalation valves
of the full face mask directly to the surrounding atmosphere.
Rebreathing in the fresh-air supply hose
is interrupted by the inhalation valve of the mask.
Since the underpressure inevitably depends
on the length of the hose during inhalation
(inhalation resistance), the hose is limited to a maximum of 20 m.
Hose devices are tied to a certain place due to the limited
length of the hoses. However, the supply of
