What
is the Ionizing Bar?
EXAIR’s new Ionizing Bar eliminates static electricity on paper,
film and plastics that can attract dust and foreign materials,
ruin product appearance, produce tearing or jamming, and zap
personnel. The electrically powered Ionizing Bar is compact,
allowing it to fit in the confined spaces of machinery, where
the charge is generated. A high concentration of positive and
negative ions produces fast static decay, neutralizing any
surface
within 2" (5cm) of the bar.
The
unique design of the shockless Ionizing Bar offers improved
performance and reliability in industrial applications. Life
expectancy has been extended by insertion molding the stainless
steel ion emitters into a durable plastic.
There are no openings or grooves to accumulate dirt that could
cause shorting or arcing. A 5kV power
source provides high performance, eliminating frequent burnouts
commonly associated with traditional
7kV bars.
The
rugged Ionizing Bar includes a five foot shielded cable with
ground. A mounting flange is provided for easy installation
and all components are fully assembled. Standard lengths up
to 48" (122cm) are available from stock and
special lengths up to 120" (3.05m), are available by special
order. Models with attached Super Air Knife to provide
more rapid static decay and larger area coverage are available.
EXAIR Model 7901 or 7907 power supply (5kV)
is required for bar operation.
Applications
include web and sheet neutralization, static control on packaging
lines, cleaning plastic parts, eliminating
jams in printing machinery and preventing hazardous personnel
shocks caused by the unwinding of stretch
films.

How the Ionizing
Bar Works
The
shielded power cable (1) carries the 5kVrms power supply
output to each capacitively coupled stainless steel emitter
point (2) of the Ionizing Bar. A ground wire (3) attached
to the bar creates a discharge path from the emitter points
to the bar channel (4). The discharge at each emitter charges
the molecules of the gases of the surrounding room air,
resulting in a shower of ions that are positively and negatively
charged (5). If the material surface has a negative charge,
it will attract the positive ions from the ionizing bar
and become balanced or neutralized. If the material surface
has a positive charge, it will attract the negative ions
from the ionizing bar to become balanced or neutralized.
The voltage potential at each emitter is high enough to
ionize the surrounding air without generating a shock when
any of the emitters are touched.
