Air is drawn into the unit to capture particles. The airborne particles pass
through an electrostatic field and receive an ionized charge. The charged
particles move into a collector section where each alternate plate is charged
with the same polarity as the particles. This drives the particles to the second
set of plates of an opposite charge to attract and collect the particles. The
cleaned air is then returned to the plant or building.
Unlike media air cleaners that use replaceable filters that plug up when dirty,
electrostatic precipitators contain permanent cells that can be washed, either
manually or with an included automatic wash system. These permanent cells do not
require added static pressure when they get dirty to pull air through them. This
typically means motors are 1 to 2 sizes smaller, saving the operator energy costs,
as well as the cost to dispose of dirty filters.

Trion’s electrostatic precipitators may be your next best mist collector.
If you have an older electrostatic precipitator, your authorized Trion
Representative may be able to help you determine how best to use it or
reconfigure it for your needs.
Industry Definitions:
24.8 ASHRAE Systems & Equipment 1996 - "Electronic air cleaners can be highly efficient filters using
electrostatic precipitation to remove and collect particulate contaminates such as dusts, smoke,
and pollen. The designation electronic air cleaner denotes a precipitator for HVAC air filtration.
This type of air cleaner can remove and collect contaminates with an average efficiencies up to 98%,
when tested in accordance with ASHRAE Standard 52.1."
4.3.1 INDUSTRIAL VENTILATION A Manual of Recommended Practice 24th Edition - "The Penny or
two-stage precipitator which uses DC voltages from 11,000-15,000VDC for ionization. It is
the most practical collection technique for the many hydrocarbon applications where an
initially clear exhaust stack turns into a visible emission as vapor condenses. Some
applications include plasticizer ovens, forge presses, die-casting machines, and various
welding operations. The pressure drop of an electrostatic precipitator is extremely low,
usually less than 1"wg, therefore, the energy requirement is significantly less than for
other (filtration) techniques."
