Chargebuster Ion Gun
Installation, Operation and Maintenance
Figure 1. EMIT Chargebuster Ion Gun
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 Point-Of-Use
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
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
“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

Features and Components
E. Disposable Filter Release / Lock Button: Push down
to release the disposable filter and hose assembly from
the console. This button should also click when properly
attaching the disposable filter and hose assembly to the
F. Disposable Filter: Filters particles, oil and moisture from
the incoming air supply.
NOTE: Failure to use clean dry air or nitrogen may result
in damage to the Chargebuster Ion Gun that is not covered
under the Limited Warranty.
The compressed gas supply must be clean dry air or
nitrogen supplied by a delivery system that utilizes a
refrigerated dryer or equivalent water removal to achieve a
limit of about 550 ppm water vapor at 35°F (1.66°C) Dew
Point. To prevent particles from entering the console, a 2
micron coalescing filter or better is recommended upstream
of the gun console. Note that the filter in the console
collects small residual particles and aerosols and does not
act as a primary filter. The console filter is rated at 0.01
micron for particulates and is effective down to 0.008 micron
for aerosols.
An adequate filter that can be recommended for the inlet
of the Chargebuster Ion Gun would be a Finite Filter Grade
10 Media Specification. This provides a 95% coalescing
efficiency for aerosols with a 0.7 micron (and greater)
particle retention. This removes gross amounts of particles,
water and/or oil and aerosols.
A Grade 6 Media provides 99.98% efficiency when almost
total removal of liquid aerosols and particles are required in
all pressure ranges down to 0.01 microns. Fine filters need
to be changed more often.
Plug one end of the included 10’ cable into the jack on the
back of the console. Plug the other end of the cable into
the unplugged Wall Transformer.

Figure 5: Mounting the console to the mounting plate
Figure 6: Inserting the disposable filter
Choose a location that will be convenient to the work area
and the gas supply. The Console takes up very little space
and is adaptable to a variety of permanent or temporary
installations. To minimize bends in the gun hose, orient the
console so that the open end points toward the work area
and the male connector points toward the air supply.
1. Use the included screws to attach the supplied
mounting plate to the threaded holes on the back of the
Figure 7: Connecting the hose and disposable filter to the
2. Connect the hose and disposable filter to the console.
Press the disposable filter release button on the front of
the console to lock it down. Push the fitting containing
the disposable filter all the way into the opening in the
console until it latches with a click. It fits only in the
correct orientation. The small plastic fitting on the end
of the disposable filter must align with the metal guide
coupling in the console. You may have to wiggle the
disposable filter slightly while inserting it.
2. Attach the plate to a flat surface, such as a wall or back
of a work bench, using suitable screws and fasteners.
When mounting to a hollow wall be sure to use #8
screws and 3/4” length anchors as a minimum.
When a gas supply is close to the work area and fitted
with a standard industrial interchange quick coupling, you
may attach the console to the air supply fitting directly. If
necessary, use a prefilter as defined in the COMPRESSED
GAS REQUIREMENTS section of this technical bulletin.
NOTE: Protect the hose from sharp objects, abrasion, and
high temperatures. Do not pull or pinch the hose while
assembling the components.
1. Insert the larger diameter end of the air filter into the
end of the flexible air hose connector. Press the metal
filter release tab at the end of the hose until it locks into
3. Attach the included 1/4” NPT female quick connect
fitting to your gas supply line. Slide the outer ring on
the fitting towards the supply line to insert the mating
fitting on the console. You can attach the console
directly to the gas supply pipe or attach it using a hose
(not supplied). If necessary, use a prefilter as defined
of this technical bulletin.
4. If you would like to use the optional foot switch, plug its
cable to the jack located at the top of the console.
NOTE: Our recommendation is to set the pressure regulator
on your air or nitrogen supply between 20 and 65 psi
(0.14-0.45 MPa). Discharge times vary depending on air
Pressures of 30-40 psi (0.2-0.28 MPa) are commonly
used for decontaminating surfaces. OSHA regulations
recommend limiting hand-held air blow-off devices to
maximum pressures of 30 psi (0.2 MPa). The hose is rated
at 65 psi (0.45 MPa) at temperatures up to 75°F (24°C), and
the rating decreases at higher temperatures. When using
high pressures, consider the ambient room temperature as
well as heat from surrounding equipment.
1. Ensure that you are not holding down the trigger, and
turn on the power switch located at the top of the
console. The power LED should illuminate.

2. Hold the gun approximately six inches from the surface
you want to neutralize and blow-off. Aim the nozzle
and hold down the trigger. The LED on the back of the
gun should illuminate. Typically, static charges are
discharged within one second.
3. Release the trigger when the surface is clean.
If the optional foot switch is installed, you may use either
the foot switch or gun trigger.
Figure 8: Using the Chargebuster Ion Gun
“All ionization devices will require periodic maintenance for
proper operation. Maintenance intervals for ionizers vary
widely depending on the type of ionization equipment and
use environment. Critical clean room uses will generally
require more frequent attention. It is important to set-up
a routine schedule for ionizer service. Routine service
is typically required to meet quality audit requirements.”

1. Turn off the console and disconnect it from its
electrical power and gas supply sources.
2. Using a cloth moistened with the IPA solution, wipe
the exterior surfaces of the console and gun to
remove any dirt or dust that may have collected.
3. Using a swab moistened with the IPA solution,
gently clean the emitter points on the gun.
Extremely dirty points increase the time needed to
discharge static and can affect the ionization
