Chargebuster Ion Gun
Installation, Operation and Maintenance
March 2017
Description
The Desco Chargebuster Ion Gun is a point-of-use
ionizer used for neutralizing electrostatic charges
to eliminate attraction, visual imperfections and
contamination issues by dislodging charged dust
and debris. It uses compressed clean dry air (CDA)
or a compressed gas supply. Less than 1 second
discharge times with ±30 volt offset voltage balance
meet the required limits of ANSI/ESD S20.20 and ESD
TR53. A 7-foot ESD hose with trigger switch allows
operators freedom of motion and minimizes awkward or
unsupported positions. The quick change filter in the
console collects small residual particles.
“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)
“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/ESDS20.20 Foreword)

MOUNTING TO A GAS SUPPLY
When a gas supply is close to the work area and
fitted with a U.S. standard industrial interchange quick
coupling, you may attach it to the console directly using
the included female quick connect coupling. If a U.S.
standard industrial interchange quick coupling is not
available on the gas supply, be sure to use a suitable
interconnect between the gas supply and the console.
Use a prefilter as defined in the COMPRESSED GAS
REQUIREMENTS section if necessary.
ASSEMBLY
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 large end of the filter into the fitting at the
end of the flexible hose. Push the filter gently until
the metal release tab clicks and locks the filter into
place.
Installation
COMPRESSED GAS REQUIREMENTS
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.
MOUNTING THE CONSOLE
Choose a location convenient to the work area and gas
supply. The console takes up very little space and is
adaptable to a variety of permanent or non-permanent
installations. To minimize bends in the Chargebuster
Ion Gun’s hose, orient the console so that the open end
that accepts the filtered air hose to the hand unit points
toward the work area, and the male connector points
toward the gas supply.
Prior to mounting, plug the RJ-11 cable from the power
supply into the jack located on the back of the console.
Use the included screws to attach the mounting plate
to the threaded holes on the back of the console. Use
suitable screws and fasteners to attach the mounting
plate to a flat surface such as a wall or the back of a
workbench. When mounting to a hollow wall, be sure
to use adequate screws and wall anchors to ensure
stability of the installation.

2. Insert the hose and filter assembly into the console
until the console’s release button latches on with a
click. The small plastic fitting on the end of the filter
must align with the metal guide coupling inside the
console. You may have to wiggle the filter slightly
while inserting it.
5. Use the included S-hook to hang the gun at the
workstation if desired.
6. Ensure that the power switch on top of the console
is in the OFF position. Connect the power adapter
to an appropriate power outlet.
NOTE: Use only Desco 19593, 50711 or 50712
power adapters. Use of other power adapters may
result in damage to the unit and void the warranty.
For optimal safety and ionization, set the pressure
regulator on the compressed gas supply to 25-65 psi
(1.4-4.5 bar). Neutralization (discharge) times vary on
gas pressure settings.
NOTE: Pressures of 30-40 psi (2.0-2.8 bar) are
commonly used for decontaminating surfaces. Please
refer to the pertinent regulations concerning maximum
air pressure on hand-held air blow devices in order to
determine a safe operating pressure.
The Chargebuster Ion Gun is rated at 65 psi (4.5
bar) inlet pressure at temperatures up to 75º F (24º
C), and the rating decreases at higher temperatures.
When using high pressures, consider the ambient
room temperature as well as heat from surrounding
equipment.
Operation
1. Ensure that the gun’s trigger is not depressed. Set
the console’s power switch to the ON position. The
green power LED located next to the power switch
should illuminate.
2. Aim the gun approximately 6 inches (15 cm) from
the surface to be neutralized and cleaned.
3. Hold down the trigger to blow ionized air. The
green LED on the back of the gun will illuminate to
indicate ionization. Typically, static charges will be
neutralized within one second.
4. Release the trigger when the surface is clean.
Desco recommends turning off the console whenever
the Chargebuster Ion Gun is not in use. This will
prevent unintentional operation.

3. Connect the male air inlet fitting on the console to
the gas supply. The console’s fitting is designed
for a U.S. standard industrial interchange quick
coupling. The console may be connected directly
to a gas supply with the included female quick
connect coupling or hose (not supplied). Use a
prefilter as defined in the COMPRESSED GAS
REQUIREMENTS section if necessary.
4. Connect the optional 19592 Foot Switch to the top
of the console if necessary.

3. Disconnect the hose and filter assembly from the
console by pulling the textured plastic ring nearby
the hose’s spring. Rocking the ring back and forth
may help loosen the filter from the console. DO
NOT pull the hose itself.
4. Pull and disconnect the filter from the hose fitting by
depressing the metal release tab. Discard the dirty
filter.
5. Install a new filter by following the ASSEMBLY
instructions on pages 2-3.
Calibration
Frequency of recalibration should be based on the
critical nature of those ESD sensitive items handled
and the risk of failure for the ESD protective equipment
and materials. In general, Desco recommends that
calibration be performed annually.
Periodically measure the offset voltage balance and
neutralization times of the Chargebuster Ion Gun to
verify that it is performing within specifications. These
measurements should be taken using a charged plate
monitor such as EMIT item 50571.
Calibration should be performed in accordance with the
ESD Association ionization standard ANSI/ESD STM3.1
or Compliance Verification ESD TR53. At a line
pressure of 30 psi (2 bars) and a distance of 6 inches
(15 cm), the neutralization (discharge) time of ±1000V
to ±100V should be less than 1 second, and the offset
voltage balance should be ±30V or better.
Maintenance
The Chargebuster Ion Gun requires very little
maintenance. Occasional cleaning of the case and
emitter points, and periodic replacement of the air filter
are all that is required. Always be sure to protect all
components from liquids and corrosive chemicals.
CAUTION: Always disconnect the Chargebuster Ion
Gun from its power and gas supplies before performing
any maintenance.
CLEANING THE COMPONENTS
1. Turn off the console and disconnect it from its
electrical power and gas supplies.
2. Moisten a cloth with isopropyl alcohol, and use it to
wipe the exterior surfaces of the console and gun.
Remove any dirt or dust that may have collected.
3. Moisten a swab with isopropyl alcohol, and use
it to gently clean the emitter points in the gun.
Extremely dirty points increase the time needed to
neutralize static charge and affect ionization offset
voltage balance.
REPLACING THE AIR FILTER
Desco recommends changing the filter every three
months or whenever it looks dirty. Replacement filters
are available as Desco item 19591.
1. Turn off the console and disconnect it from its
electrical power and gas supplies.
2. Hold down the filter release button on the side of the
console.
