2.2. Function
The SavOxCap 60 supplies the wearer of the apparatus with oxygen which is
created from the chemical potassium hyperoxide (KO
2
). In an emergency, the
container is opened and the respiratory protection device is taken out.
The apparatus has a closed breathing circuit. When in operation, the exhaled air
is transferred to the chemical canister with the potassium hyperoxide. The
potassium hyperoxide reacts with the humidity and the carbon dioxide of the
exhaled air and, at the same time, creates oxygen and heat. The air for inhalation
prepared in this way is fed to the breathing bag and is then inhaled again.
The amount of resulting oxygen depends on the intensity of respiration. Increased
respiration (more carbon dioxide, more humidity) increases the formation of
oxygen or vice versa.
After actuating the starter, the breathing bag immediately fills with oxygen and
breathing can begin.
When the apparatus is used for breathing, the KO
2
canister warms up, as does
the inhalation air, gradually. This is normal and indicates the correct operation of
the apparatus.
The supply of oxygen starts to decline if inhalation becomes more difficult and the
breathing bag starts to collapse.
Attention!
The SavOxCap 60 must only be opened for use! Otherwise humidity
from the ambient air can penetrate the open unit and affect the
performance. Used or opened units must be replaced by new units.
