METHOD 3 (As needed in harsh environments)
This cleaning method will remove all contaminants. Since
this method requires direct contact with emitter electrodes,
it is critical that the ionizer be unplugged before beginning
this cleaning process.
Disconnect power to the ionizer.
Dampen the end of a non-linting cotton swab with isopropyl
alcohol.
Alcohol is flammable. Extreme caution should
be used when handling any flammable solvent.
Reaching
carefully through the grill bars, gently wipe each electrode
until clean. Avoid bending any electrodes. If any electrodes
become dislodged, nudge them with the tail end of the
cleaning brush until they remain no less than 1/4" from any
object.
Wait 15 minutes for alcohol to evaporate before
plugging in the ionizer.
THEORY OF OPERATION
The Bench Top Blower Ionizer employs a safe non-nuclear
AC ionization source. AC systems utilize emitter electrodes
that are switched rapidly between positive and negative high
voltage, usually at the power line frequency (50/60 Hz). The
ionizer’s unique Faraday Balance System monitors ion output
and automatically adjusts the unit to reach an equilibrium
at low offset voltage or balanced ion flow. The ionizer is
designed to achieve balance under extreme conditions and is
uniquely able to maintain balance in most any environment.
Ions are emitted in an efficient laminar flow. This reduces
air turbulence and ion recombination, prolongs cleanliness
and increases efficiency. The ionizer’s unique tri-metallic ion
emitter electrodes produce a high ion output for rapid charge
dissipation.
The Bench Top Blower Ionizer is engineered for efficiency
and durability, making this bench top ionizer highly
dependable and cost effective.

ADJUSTMENT
There are no user adjustable or serviceable parts inside the
ionizer. Adjusting or dismantling your ionizer may create
dangerous conditions and unauthorized modifications will
void the product warranty. Servicing should be performed
only at the factory, or by a technician trained in high voltage
circuits. See warranty section for repair information.

Neutralization Efficiency (Decay Time)
The comparative efficiency of bench top ionizers is
determined by a standard test published by the ESD As-
sociation (Draft standard S 3.1). The decay rates mea-
sured using this standard for the ionizer are shown in the
following diagram. The performance of the ionizer was
measured with the unit positioned at varying distances
with the fan speed on high.
