2.2 ELECTRONIC CELL
The unit employs a two-stage electronic cell for particulates
collection. It has a stage of ionizer wires and a stage of collector
plates. The ionizer wires are maintained at several thousand
volts, which produce a corona that releases electrons into the air
stream. As the dirty air passes through the intense high voltage
electric field surrounded the ionizer wires, all particles, even the
smallest are given an electric charge. The air passes into the
collector stage where the alternate parallel plates have positive
and negative charges, creating a uniform electrostatic field. Since
opposites attract, the charged particles stick to the collector
plates, having an opposite electric charge. Consequently, the air
leaving the air purifier contains very few particles. Theses
electrons attach to dust particles and give them a net negative
charge. See Fig. 2.2-2.
How Does the Electronic Cell Work?
The high voltage power supply provides the cell high voltage to
the ionizer section and low voltage to the collector section
through the two power contact terminals. If the power supply is
broken the cell cannot work, failing to collect the particulates in
the air.
Fig. 2.2-2 How does the electronic cell work.
The cell needs high voltage to the ionizing wires and low
voltage to the positive plates of the collector section.

Fig. 2.2-1 Remove the electronic cell.
Stop the operation and unplug the power
plug from the electrical outlet.
Open the front
panel and take out the cell.
The first stage, the ionizer section of the cell is the
charging section composed of ionizing wires and
grounded plates. When the power supply provide
high voltage to ionizing wires it create a strong
electrical field and give charges to the particles in
the air stream. Some of the charged particles are
attracted to the ground plates.
The second stage, the collector
section of the cell is the collecting
section composed of alternate
parallel plates which are positive
plates and ground plates. When the
positively charged particles are
passing through the collecting
section they will be trapped by the
ground plates.
