9.3 Aspiration efficiency
Maximal suction
The maximal suction exerted by the Combi and Suction MODULES depends on the input pressure of the
oxygen supply. The data below are valid for a 2 litre aspirate bottle.
Tolerance limits ±10%. If a bacterial filter is used,
the aspiration efficiency will diminish by between
1 and 3 l/min, depending on the atmospheric
humidity.
Aspiration efficiency of Suction MODULE
The suction exerted by the Suction MODULE varies according to the degree of vacuum selected at any given
time. The data below are valid for a 2 litre aspirate bottle.
Tolerance limits ±10%. If a bacterial filter is used,
the aspiration efficiency will diminish by between
1 and 3 l/min.
