ELECTROSTATIC CHARGE REMOVER
"0V" neutralization achieved by light
OVERVIEW
The PhotoIonBar is an electrostatic charge remover using photoionization that neutralizes static electricity by irradiating the charged object with weak soft X-rays.To neutralize static charges, ordinary ionizers generate ions by corona discharge and send them toward the charged object by air flow. Unlike these old methods, the PhotoIonBar emits
weak soft X-rays that directly ionize the air around the charged object to
neutralize static charges. The PhotoIonBar needs "NO AIR FLOW" and
generates "NO DUST" and "NO ELECTROMAGNETIC NOISE".
* Controller and cable are sold separatelly.
Here's why photoionization works so well!
● 0V neutralization
Fine ion balance makes no opposite charging
● Generates no dust and no electromagnetic noise
● Needs no air flow
"Soft X-ray irradiation area" = "Static charge
neutralization area"
● Maintenance free (needs no electrode cleaning)

"PHOTOIONIZATION" MECHANISM
When X-rays hits a stable atom or molecule, an electron is ejected out of the atom or molecule leaving a positive ion
(atom or molecule of positive polarity). The ejected electron then combines with another stable atom or molecule to
form a negative ion (atom or molecule of negative polarity). As a result, the same amount of positive ions and negative
ions are generated.
These ions are also generated in the vicinity of a charged object, and they are attracted to the charged object to neutralize the static charges.

CHARGE NEUTRALIZATION EFFECT
In photoionization, ions are generated over the entire area irradiated with soft X-rays. This improves the charge neutralization efficiency and also shortens the charge neutralization time.

SHIELDING EFFECT (%)
Using the PhotoIonBar requires "soft X-ray shielding"
during operation. However, the soft X-rays emitted from the
PhotoIonBar are only at a strength of about 3 to 4.9 keV
and so only need the following materials for 100 %
shielding.

THICKNESS (mm)
Note 1: Shielding effect is measured when distance between PhotoIonBar and
survey meter is 100 mm and shielding material is placed between them
(survey meter side).
Note 2: The surface of PVC (polyvinyl chloride) plates may blacken when directly
irradiated by soft X-rays from a very short distance (within 100 mm) for a
continuous period over several months, but this is not a problem. Such
type of changes will not occur in iron and aluminum material plates.
