2.2.3 Ionization unit
General
The Feather Duster V2 is equipped with an ionizer unit whose purpose is to reduce
or eliminate static charge from the cleaned surface. The ionizer unit includes an
ionizing bar and an ionizing air air knife.
High voltage generator
The AC high voltage generator produces both positive and negative ions at a rate
of 1to 68 times per second (1Hz-68Hz line frequency).
As shown in the following figure, the ionizing bar has an adjustable excitation
voltage. The generation speed of positive ions is improved as the increasing setting
voltages, from 0V to 1000V.

During the first half of the cycle, the discharge begins when the potential reaches
up to setting voltage. During the second half of the cycle, negative ions are
generated when the potential reaches the negative value of the setting voltage.
