Revolutionary Technology
for the New Millennium
During operation, the contaminated air to be cleaned passes
across Trion’s unique spiked ionizer blades which are sup-
ported between flat grounded electrodes. Revolutionary to the
industry, the blades are made of stainless steel that will not
rust or break, thus eliminating costly maintenance time and
replacement costs.
Prefilter/Impinger
The prefilter/impinger track is a standard integral part of the
Model 75 ESP cabinet. A 2” rail is positioned upstream of the
ESP collector cell to accommodate a standard 40% free area
perforated panel for even air distribution, a metal mesh prefilter
for light oil mist, or an impinger for more heavy, fluid or semi-
fluid particulate matter. The particulate matter may range in
viscosities from that of water to relatively heavy greases. In
heavy loading applications, the liquid particles strike the
impinger, coalesce into droplets and then flow to the drain pan
below. If the particles are of a high viscosity nature that do not
readily flow into the drain pan, they are periodically flushed
down the drain with an optional bolt on collar containing an
integral wash system located upstream of the impinger. A simi-
lar track, located downstream of the unit, is designed to house
a perforated panel and functions as an air distribution device as
well as a safety screen like its upstream counterpart.
The DC voltage supplied to the blades creates a high intensity
field where the particulate matter in the air becomes electri-
cally charged. The charged particles then pass into a collector
plate section made up of a series of equally spaced parallel
plates. Each alternate plate is charged with the same polarity
as the particles, which repel, while the interleaving plates are
grounded, which attract and collect.
Periodically, depending on the type and amount, the con-
taminate is washed into the cabinet drain basin by an
automatic activated integral washing system that is located
on both the upstream and downstream sides of the ionizing-
collecting cell(s).
A programmable logic controller (PLC) and dual solid-state
Pulse Width Modulated (PWM) high voltage DC power supply
are housed in a remote-mounted NEMA 12 enclosure.

also available.
The unit operates in the higher efficiency collection range,
upward of 95% DOP Method, on particles ranging in size from
10 Microns down to 0.01 Microns in size.
In applications requiring extremely high collection efficiency
and low resistance to air flow, two or three electro-
static sections may be placed inline to create a double or
triple pass unit.
Durable, compact cabinetry
When you invest in a Trion Model 75 you want it not only to fit
your unique needs, but your individual space as well.
And you want it to last. Trion housings are constructed using
16-gauge zinc-coated steel. Then all welds and the finished
area of welds are treated with a corrosion and rust-inhibiting
