Air Supply Connection
Turn off air at regulator (or compressor). Insert the brass male
connector (1/4” tubing to 1/8” pipe thread) into an available port
on the regulator. If all ports are being used, a “T” or “+” may be
added to create more ports. Connect the 1/4” tubing to the male
connector on the needle valve on back side of the unit, following
the instructions given below.
To connect tubing or filter to quick connect fitting:
Cut end of plastic tubing square and clean. Push against the collar
with thumbnail. While holding collar in, push tubing into the fitting
until it bottoms out completely.
To release tubing or filter from quick connect fitting:
Push against the collar with thumbnail. While holding collar in,
push tubing inward slightly, then pull tubing out.
IMPORTANT NOTE: User should exercise caution when using
any compressed air device.
The ion balance is
affected by many
factors, such as
distance, air flow,
humidity, and emitter
contamination.
Therefore, before using
this device around
components and
Avoid sharply bending or a crushing the black convoluted tubing
under feet, rolling chairs or other furniture.
IMPORTANT NOTE: These air nozzles are not explosion proof.
Do not use in environments where volatile materials are
present.
EMIT solid-state electronic equipment is compact and rugged but
should be treated as sensitive electronic equipment. With proper
installation and a continued preventive maintenance program you
will ensure the proper performance of the unit.
Theory of Operation
The Ion Python and Neutralizing Hand gun employ high voltage
AC to create a balanced ion field. AC systems utilize emitters
that are switched rapidly between positive and negative high
voltage, usually at the power line frequency (50/60 Hz). The
emitter is located at the end 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 air nozzles
also eliminate 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 volts voltage offset
tested in accordance with ANSI ESD S3.1. Air Nozzle Ionizers
typically can provide ±20 volt offset balance.
Maintenance
“Periodic verification of ionizers is performed to provide continuing
indication of required ionizer performance. The more critical
the ionizer application, the more important it is to verify that the
ionizers are working correctly. Periodic verification testing is
most often performed under actual use conditions. In general, all
ionizers should be checked, rather than a random sample.” ESD
SP3.3 Periodic Verification of Air Ionizers, A2.1
“Periodic verification procedures should be a part of the initial
acceptance process to provide baseline data for comparison
with future measurements. A schedule should be established for
periodic verification testing.” ESD SP3.3 Periodic Verification of
Air Ionizers, section 7
“Ionizers should be tested for discharge time and balance
after they have been installed in the use location. The time
intervals for subsequent measurements will depend on the users
requirements.” ESD Handbook TR 20.20 paragraph 5.3.6.6.5
These units need very little maintenance. In order to maintain
the optimum performance of your unit, the following maintenance
procedures must be performed on a regular basis.

Electrical Requirements
The Ion Python and Neutralizing Hand Gun must be connected to a
properly grounded receptacle for the units to operate properly. It is
recommended that the AC outlet be checked for proper wiring and
grounding. (Use Desco 98130 AC Outlet Tester or equivalent)
Do not under any circumstances remove the ground pin from the
plug of these units.
NOTE: Grounding of these units is necessary not only to ensure
that they operate properly, but to eliminate the possibility of an
electrical shock.
Operation
Turn on unit with switch on the front panel. The green light
indicates that the air nozzle is ready for use. Point nozzle at object
to be cleaned or neutralized.
When using the Ion Python, actuate foot pedal switch to initiate the
flow of air and neutralizing ions. Best results are normally obtained
when holding the nozzle within .5’ to 1.5 feet of the item being
neutralized.
For the Neutralizing Hand Gun, push button on the nozzle body
to initiate the flow of air and neutralizing ions. Best results are
normally obtained when holding the nozzle within 2 or 3 feet of the
item being neutralized; hold the nozzle closer when required.
NOTE: Unit is not designed for continuous duty.
A needle valve is located on the back of the unit for fine
adjustments to the air flow, or for shutting off the air to the nozzle.
Airflow on the unit can be adjusted from a gentle blow to a strong
blast, allowing for use in most applications. Do not obstruct the
air jet with fingers or other objects. Do not force any object into
the air jet hole; this action can easily damage the emitter pin and
prevent the controller from producing the ionization necessary for
neutralizing static charges.
