Viper Ion Gun
Installation, Operation and Maintenance
Description
The Desco Viper 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 special nozzle (19596) may be purchased
separately for use with nitrogen. Fast discharge times with
±15 volt offset voltage meet the required limits of ANSI/
ESD S20.20 and ESD TR53. A high frequency piezo AC
power supply is located Inside of hand piece to maintain
consistent ionization performance with longer hose lengths
(standard 6' hose included) and eliminate the need for a
remote console. The light weight of the Viper Ion Gun (less
than ½ pound; 200 grams) allows for comfortable extended
use by operators. The Viper Ion Gun is designed with slotted
tips to meet the OSHA requirement for pressure relief. A
green LED on the back of the hand piece illuminates when
the trigger is depressed to indicate that the gun is outputting
ionized air. A red LED indicates abnormal output. Normal
power consumption is approximately 2.5 Watts.
The Viper Ion Gun and its accessories are available in the
following item numbers:

“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/ESDS20.20-2007 Foreword)

Features and Components
Operation
NOTE:
• Do not operate the main unit by turning the nozzle
toward a human body, especially to the face or to the
eye of a person. This may cause serious injury to the
person.
• Do not let the nozzle of the main unit touch conductive
or live parts.
• Do not drop the ion gun as it may damage the
piezoelectric power supply embedded in the unit.
• This product emits ozone. Do not use this products in
an enclosed space.
1. 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 green LED on the back
of the gun should illuminate. Static charges are typically
discharged within one second.
2. Release the trigger when the surface is clean.

A. Output Air Nozzle: Outputs ionized air when the trigger is
depressed. Use the Desco 19596 Nitrogen Nozzle Tip when
using nitrogen as the air supply.
B. Hanging Hook: Use to hang the hand piece when not in
use. The hook may be rotated 90 degrees.
C. Power LED: Illuminates green when the trigger is
depressed and ionized air blows out the nozzle.
D. Alarm LED: Illuminates red when the emitter is dirty or
short-circuited.
E. Trigger: Depress to output ionized air.
F. Air Input Port: Use the one-touch joint to secure a 6 mm
air tube to the ion gun.
G. Power Cable: Connect the power cable to the power
adapter to supply power to the ion gun.
Installation
1. Connect the Viper Ion Gun’s power cable to the power
adapter.
2. Connect the power adapter to an appropriate power
outlet.
3. Insert an air tube (6 mm outside diameter) into the ion
gun’s air input port.
4. Connect the other end of the air tube to a source of
clean dry air or nitrogen.

Maintenance
“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.” (ESD
Handbook TR20.20 section 5.3.6.7 Maintenance / Cleaning)
EIA-625, recommends checking ionizers every 6 months, but
this may not be suitable for many programs particularly since
an out-of-balance may exist for months before it is checked
again. ANSI/ESD S20.20 section 6.1.3.1 Compliance
Verification Plan Requirement states: “Test equipment shall
be selected to make measurements of appropriate properties
of the technical requirements that are incorporated into the
ESD program plan.”
Cleaning the Emitter Point
To maintain optimum neutralization efficiency and operation,
cleaning should be performed on a regular basis. Use the
Desco 60506 Emitter Point Cleaners or a swab dampened
with isopropyl alcohol to clean the ion gun’s emitter point.
1. Disconnect the ion gun from its power supply and air
supply.
2. Remove the nozzle.
3. Gently clean the emitter point using a swab dampened
with Isopropyl alcohol. Screw the nozzle back onto the
ion gun when complete.
Desco 19597 Replacement Emitter Pins are available should
the emitter point need to be replaced.
