Introduction
Meech Blowers are powerful static eliminators which will give many years of excellent
service, provided that the following instructions are observed closely.

General Notes On Operation
The typical Meech Blower installation consists of one or more blowers connected to a
Meech Power Unit.
THIS APPLIANCE MUST BE GROUNDED/EARTHED THROUGH THE MAINS
ELECTRICAL SUPPLY.
The Power Unit converts the primary electricity supply into a high voltage, low
amperage output. This energy is transferred to the Meech Bars in the mouth of the
blower by the HT cable.
The titanium pins of the bars emit the energy to form an ionised air corona. The
fans inside the blower provide an air ow to transport the corona to the object to be
neutralised. When a statically charged object passes through this corona, the free
moving ions are attracted to the opposite charge on the object. In this way the static
electricity is neutralised. Unused ions in the corona recombine or are discharged to
earth.

Installation
The correct positioning of the blower is vital to the efcient operation. Please observe
the following instructions.
Distance From Object
Although the blower has excellent long range neutralisation capabilities, the general
rule is that it should be as close to the object as possible.
If we say neutralisation power at a distance from the object of 30cm is 100% then the
relative n eutralisation performance at longer distances.
Distance “A” Relative Performance
30 cm 100 %
50 cm 90 %
100 cm 60 %
200 cm 30 %

Intervening Objects
If the ionised air is blown through earthed objects (eg a machine frame or cross-rods),
these will absorb some of the ionisation and so reduce the neutralisation power. Avoid
this whenever possible.
CAUTION: It is recommended that the following procedure be observed for safe
operation of the Model 935 Blower:
The supply voltage of the power supply must be interlocked with the ON/OFF
control of the machine to which the equipment is tted.
This will ensure that whilst the machine is switched off and thus operatives may gain
access to the machine and our equipment, there will be no danger to operatives
working in close proximity to our product.
It is assumed that normal safety barriers are in place on the machine to ensure that
operatives are unable to access the machine and hence our equipment whilst the
machine is switched ON.

Caution
It is recommended that the following procedure be observed for safe operation of
the Model 935 Blower:
1. The supply voltage of the power supply must be interlocked with the ON/OFF
control of the machine to which the equipment is fitted.
2. This will ensure that whilst the machine is switched off and thus operatives
may gain access to the machine and our equipment, there will be no danger
to operatives working in close proximity to our product.
3. It is assumed that normal safety barriers are in place on the machine to
ensure that operatives are unable to access the machine and hence our
equipment whilst the machine is switched ON.

Maintenance
The Static Eliminator bars in the mouth of the blower should be cleaned regularly
to keep the emitter pins free from dust and other contaminants. A toothbrush is
ideal for this.
Cleaning of the emitter pins of the ionisation bars:
* ensure the blower is switched off and isolated from the mains electrical supply.
* remove the front black plastic grill by bending gently and pulling out.
* using a tooth brush ( or a similar brush with non conductive bristles), brush
the pins and upper surface of the two white ionising bars.
* With a cloth clean the exterior and interior surfaces of the blower.
* Replace the black plastic grill by the reverse procedure.
CE Approval
