The first adjustment of the air flow in the fume cupboard is done quickly according to the position of the sash. Another focus adjustment takes place at the same time based on the speed measurement. The system adjusts the exhaust air damper and keeps the desired air flow in the sash opening (usually 0.5 m/s).
The system remembers the focus adjustments it has made and uses them in its subsequent adjustments. The system learns all the time and is able to take into account the individual characteristics of the fume cupboard and the ductwork.
