Description
The EMIT Portable Ionizing Air Gun is a ready-to-use
unit for use in applications and areas where
electrostatic charge can create manufacturing or
handling problems. This unit quickly and effectively
neutralizes bulk static charges and aids in controlling
contamination by dislodging dust and debris attracted
by static electricity.
The Portable Ionizing Air Gun meets or exceeds the
recommended technical requirements of ANSI/ESD
S20.20 tested in accordance with ANSI/ESD S3.1.
The Portable Ionizing Air Gun is designed for
point-of-use applications. Ionizers are useful
in preventing electrostatic charge generation,
ElectroStatic Discharge, and ElectroStatic Attraction.
ANSI/ESD S20.20 Paragraph 6.2.3.1 Protected
Areas Requirement states: “Ionization or other
charge mitigating techniques shall be used at the

workstation to neutralize electrostatic fields on all
process essential insulators if the electrostatic field is
considered a threat.” Ionization is used to neutralize
charges on process necessary insulators and isolated
semiconductors. Some examples of process necessary
insulators are: the PC board itself, plastic test stands,
plastic housing where a PCB may be mounted, as well
as computer monitor screens and regular cleaning
wipes. Examples of floating or isolated conductors are:
loaded PCB mounted in a stand where the pins are not
contacting the dissipative workstation.
NOTE: The unit is not recommended for continuous
use.
THEORY OF OPERATION
The emitter is located inside of the nozzle. This emitter
produces large amounts of positive and negative
ions, which mix with the air supply and create a highly
effective neutralizing field. Any material within this
field will be neutralized rapidly. The ionizing air flow
removes contamination by dislodging dust and debris
which is attracted to a material’s surface by static
charges. Once static charges are neutralized, dust
particles and other forms of contamination are freed
and carried away by the air stream. EMIT ionizers
meet the ANSI/ESD S20.20 minimum recommended
technical requirement range of less than ±50 V voltage
offset tested in accordance with ANSI EOS/ESD S3.1.
The EMIT Portable Ionizing Air Gun provides ±30 volt
balance.

I. Open the Battery Container Lid by using a coin to
turn the plastic lock.
II.Insert4AABatteriesthencloseandlockthelid.
III.Insertthe4mmdiameterairtubetotheAirInlet
and check to see if the connection is secure.
IV. Connect one end of the Quick Disconnect
Adapter to the air supply/source and the other
end to the air tube from the Ionizing Air Gun.
NOTE: Ensure that the air supply/source is set within
the 10 – 65 PSI range.
Operation
AIR INJECTION TEST
Pulling the trigger lightly, approximately halfway, will
release air from the emitter nozzle. The Active Power
LED located on the backside of the unit should not
illuminate.
If the air does not come out vigorously with a hissing
sound, check the following:
•Makesurethattheairtubeisattachedfirmlytothegun
•Makesuretheairsupplyconnectionsaresecure
ION INJECTION TEST
When the trigger is completely pulled, the gun will
release an ionized air flow. This is indicated by the
illuminated green LED located on the backside of the
unit. If the LED does not illuminate, check the following:

USING THE PORTABLE IONIZING AIR GUN
To blow ionized air, pull the trigger all the way in.
Ensure that the green LED is illuminated.
To blow air, pull the trigger halfway. Ensure that the
green LED is not illuminated.
Specifications
Air Pressure Range: 10 - 65 PSI
Rated Voltage for Power Supply: Output 6 VDC, 2.5 W
Maximum Relative Humidity: 90% non-condensing
Operating Temperature Range: 0°C - 50°C
Storage Temperature Range: -10°C - 50°C

AIR REQUIREMENTS
Always supply the Portable Ionizing Air Gun with
filtered, dry compressed shop air. Using nitrogen is not
recommended with this product. If the air is not dry,
damage to the equipment may result and the warranty
will be voided. Dirty air can introduce moisture and oil,
contaminating the units’ emitter assembly along with the
materials to be cleaned or neutralized.
Filtersmustthereforebeusedatalltimesupstream
of the air nozzle. A water trap-type pre-filter should
be used in conjunction with an oil coalescing-type
filter. Also drain all moisture traps regularly to prevent
moisture in the line. Several drains per day may be
necessary, especially in areas of high humidity.

The Portable Ionizing Air Gun may be operated over a
range of 10 - 65 PSI.
The specific pressure needed will depend upon the
application. Pressures exceeding 65 PSI are not
recommended since these higher pressures are
detrimental to effective ion production, and may
damage the unit.
CAUTION: These air nozzles are not explosion proof.
Do not use in environments where volatile materials
are present.
