Chargebuster Ion Gun
Installation, Operation and Maintenance
Figure 1. EMIT Chargebuster Ion Gun
Description
The EMIT Chargebuster Ion Gun is a Point-of-Use
Ionizer. It uses compressed air or nitrogen to neutralize
static charges in localized areas. Most companies
address ElectroStatic Attraction, visual imperfections,
and contamination issues by dislodging charged dust and
debris with compressed air ionizers. “There is sometimes
a need to provide static control in a small defined area or
location. This may be done to provide static control within
production equipment, in mini-environments, or to facilitate
particle removal from part of a product. Ionizers used for
this purpose may be blow-off guns or nozzles that work
with a supply of compressed air or nitrogen. They may use
either nuclear, soft x-ray or any of the previously described
types of corona ionization technology. It will be important
to choose a method of ionization and cleanliness of the
gas supply that is appropriate to the work area.” (ESD
handbook ESD TR20.20 section 5.3.6.5.2.4 Point-Of-Use
Ionization)
The modular and ergonomic design includes an ESD
protective flexible hose and is easily controlled by
depressing the trigger. The EMIT Chargebuster Ion Gun
meets or exceeds the required limits of ANSI/ESD S20.20
when tested in accordance with ANSI/ESD S3.1 and ESD
TR53.
Compact and lightweight, the Chargebuster Ion Gun’s
console can be mounted anywhere on the workstation for
easy access. The console connects to any supply of clean
dry air or nitrogen, and an internal disposable filter collects
residual particles, oil and moisture. The console, gun, and
air hose are static-dissipative. The 7 foot hose allows for
convenient neutralization of localized areas where desired.

The Chargebuster Ion Gun reduces a static charge of
±1000 V down to ±100 V in less than one second at a
distance of six inches (30-psi /0.2MPa inlet pressure).
Refer to the ESD Association ANSI/ESD Standard STM3.1
for the test procedure. The offset voltage (balance) is
within ±30 V of zero at a distance of six inches, significantly
less than the required limits of < ±50 volts per ANSI/ESD
S20.20.
“Necessary non-conductors in the environment cannot
lose their electrostatic charge by attachment to ground.
Ionization systems provide neutralization of charges on
these necessary non-conductive items (circuit board
materials and some device packages are examples of
necessary non-conductors). Assessment of the ESD
hazard created by electrostatic charges on the necessary
nonconductors in the work place is required to ensure
that appropriate actions are implemented, commensurate
with risk to ESDS [ESD sensitive] items”. (ANSI/ESD
S20.20-2007 Foreword)
“The primary method of static charge control is direct
connection to ground for conductors, static dissipative
materials, and personnel. A complete static control program
must also deal with isolated conductors that cannot be
grounded, insulating materials (e.g., most common plastics),
and moving personnel who cannot use wrist or heel straps
or ESD control flooring and footwear. Air ionization is not
a replacement for grounding methods. It is one component
of a complete static control program. Ionizers are used
when it is not possible to properly ground everything and as
backup to other static control methods. In clean rooms, air
ionization may be one of the few methods of static control
available.” (ESD Handbook TR20.20 Ionization, section
5.3.6.1)
