5.3 Aeration and micro injection valve (Valve block)
The rotational vacuum concentrator is equipped with an electromagnetic
aeration and injection valve. The rotor chamber is aerated through this
valve after the end of the evaporation process (manual and program
mode).
In addition, this valve can also inject air. If the vacuum value falls below the
preset value, this valve opens briefly to ensure a constant vacuum.
