Introduction
The Meech 954v2 Ionising Air Gun is an upgraded model, that provides exceptional
performance when neutralising static charges and removing dust and contamination
on a wide range of industrial processes. The 954v2 has many improvements over its
predecessors due to innovations in engineering. These include the use of additive
manufacturing that make the 954v2 60% faster and 40% lighter than the previous
version.

Unpacking and Inspection
The Model 954v2 Ionising Air Gun has been carefully packed at the factory in a
container designed to protect it from accidental damage. Nevertheless, we recommend
careful examination of the carton and contents for any damage. If damage is evident,
do not destroy the carton or packing material and immediately notify the carrier of
a possible damage claim. Shipping claims must be made by the consignee to the
delivering carrier.
General Notes On Operation
The typical Meech ionised air gun installation consists of one or more guns connected
to a Meech power unit.

The power unit provides the high voltage AC supply that is required for eective
ionisation. The ionising airgun is connected to the power unit by a tough, exible
conduit and high voltage cable. The high voltage is fed to a sharp titanium emitter pin
via a safety resistor that renders the pin safe to touch. A corona is generated at the tip
of the pin, ionising the surrounding airow.
The ionised airow will neutralise the target surface, releasing the surface
contamination and allowing it to be blown o.

Installation
Compressed Air
The compressed air supply must be clean and dry. Meech recommend the use of a
5 micron coalescing lter. Water or oil in the air will damage this product. The Meech
guarantee does not cover this. The use of a pressure regulator will allow the pressure
to the gun to be set to the correct level for the application.
A typical operating pressure for the 954v2 is 3.5 bar / 50 psi. The gives a good
balance of ionisation and cleaning performance. However, depending on the
application, higher or lower pressures may be required. Air Connection to the 954v2 is
via a standard 6mm push-t tting.
Electrical connection
Electrical connection is to a Meech Model 904 7kV power supply. Please refer to the
904 Power Supply operating instructions to ensure that your ionising gun is correctly
and safely connected to its power supply. A copy of this can be downloaded from

Maintenance
Ionisers require periodic cleaning. During normal operation, dirt may build-up on
the emitter pin. The rate of this contamination will depend on the cleanliness of the
compressed air supply. The contamination will cause a reduction in performance.
Typically, weekly inspection/cleaning is sucient.
The emitter and the inside of the nozzles can usually be cleaned using a cotton bud.
If the emitter has become very dirty, it may need to be removed before cleaning.
To remove the emitter, insert a 3mm nut spinner into the end of the nozzle and
unscrew it counter-clockwise.
The nut spinner Meech uses is a BAHCO (BE-7803)
Once removed, the pin can be cleaned. A toothbrush is deal for this.

The exterior of the nozzle can be wiped down with a damp cloth.

equipment please contact Meech International directly or your local Meech distributor.
