INTRODUCTION
This electronic air cleaner is technically known as a two-stage electrostatic
precipitator. The air cleaner is designed to remove airborne particulates,
including dust, dirt, smoke, pollen, virus, spores, bacteria and mold, from indoor
air.
Air movement through the unit is provided by the heating, air conditioning or
ventilating system blower. As dirty air enters the air cleaner, the air passes
through a metal mesh prefilter. The prefilter prevents lint, pet hair and other large
particulates from entering the air cleaner. It its important that these filters be in
place to prevent excessive dirt loading of the air cleaner collector cells. These
filters extend the time between maintenance of the air cleaner collector
cells.This allows the ionizing-collector cells to provide clean air for a longer
period between washings.
The prefiltered air then passes through a two-stage Electronic Air Cleaner. In the
first stage, all airborne particulate, even submicron size, are electronically
charged (positive) as they pass through the ionizer. The ionizer field is set up by
a corona discharge emanating from the fine, tightly strung wires suspended
between two adjacent flat plates. In the second stage, the charged particulate
passes through an intense electrical field established between alternately
charged and grounded parallel collector plates. Here, the positively charged
particulate is attracted to the negatively ground plates and removed from the air
stream.
