The EnviroSept is a highly efficient, non-ionizing,
electronically enhanced media filter that utilizes the concept of
dielectric polarization to effectively remove sub-micron particulate.
The concept of dielectric polarized media filtration,
is effected through the use of a steady-state electrostatic force
field acting on a dielectric media such as our special blended network
of polywool fibers.
The EnviroSept Electronic Air Cleaner, utilizing
an input of 24 volts AC, generates a 7,000 volt positive DC charge
from its proprietary solid state power head. This charge, applied
to the central grid, polarizes the ½' thick polywool blended
collector pads on either side of the grid. These pads are held in
place by the two outer screens, which are grounded. Therefore, the
EnviroSept Electronic Air Cleaner is really two filters in one due
to the symmetry about the central grid.
An electrostatic field, when imposed on a bed of
our polywool fibers causes each fiber to be polarized, i.e., to
cause a charge shift within the fiber. This results in each fiber
being positive and negative on opposite sides of each fiber, in
the direction of the high positive electrostatic field. Simply stated,
we are creating millions of tiny powerful magnets to attract and
hold air particles. Furthermore, particles entering the electrostatic
field become polarized also, which means that they have a spacial
varying charge distribution. They are attracted, with a force proportional
to the square of the average hemispheric charge density, by the
alternate polarized side of each collecting fiber. The use of a
static electrostatic field (i.e., one without current flow and corona
discharge) is important, since it prevents arcing and any generation
of undesirable ozone.
In addition to the application of electrostatic polarization,
the EnviroSept employs the principles of impingement and agglomeration.
Impingement is the process that all media filters use to trap large
air particles. These large particles build up on the front of the
filter, while the smaller particles are collected through the media
pads. Agglomeration of particles takes place as the all the particles
having been polarized, collect together into larger particle that
are collected on the charged media fibers.
