Introduction The Meech Model 914 has been designed to meet the most arduous of static elimination problems. The special resistive coupling of its emitter pins renders them shockless, whilst giving powerful static neutralisation performance. This enables the bar to eliminate very high static charges on high speed webs and at longer ranges than has been previously possible.
Electrostatically charged products which pass through this corona are immediately neutralised and become static free. Under test conditions, the Meech Model 914 has been found to give charge decay times that are up to eight times faster than standard AC shockless...
Installation The 914 Bar can be placed between 25mm and 100 mm from the surface to be neutralised. It is important to ensure that the target surface has free air on both sides and that earthed metal objects are, where possible, at least 20 mm away from the bar.

However, it is good practice to provide a secondary grounding through the fixing points where practical. The HT cable and armoured conduit require connection to a Meech model 905 power unit. Please consult the 905 instruction manual for further instruction.

3. Avoid proximity to earthed parts of the machinery as this will distort the corona and reduce its efficiency. 4. If bars are needed on both sides of the material, they should be staggered. 5. The bars must be earthed for correct operation. If in any doubt, run an earth wire from the bar to the earth stud on the power unit.
Technical and Construction Operating voltage 5.0 kV AC Max temperature 85°C Length : Available in lengths of 80 mm to 4000 mm in 25 mm steps. Overall length is 60mm greater than the effective length. Cable 2 metres of HT cable shielded in flexible conduit is supplied as standard.
Ionising bars will need periodic wiping to clean grey deposits from the surface of the bar. A cloth moistened with a small amount of IPA or methylated spirits is recommended. Should you have any additional questions regarding the maintenance of Meech equipment please contact Meech International directly or you local Meech distributor.
The Model 914 ionising bar forms part of a system, comprising the bar itself and a Model 905 Power Unit. To verify where a fault may have occurred it is important to test each item of the system individually.

2. Disconnect all ionising bars from the power unit. 3. Follow the test procedure for the Model 905 Power Unit. This can be found in the instruction manual of the Model 905.

5. Using a high voltage probe and meter measure the voltage on the pins of the ionising bar. This voltage should be approximately 4.5kV. 6. If the voltage is below 4.0kV then the bar should be returned to Meech for service and/or repair.

Holding the wire insulation, approach any of the bar emitter pins with the bare end of the wire or metal clip end. As the pin is approached, a small faint spark should jump from the pin to the wire. ...
Repairs And Warranty The 914 bar is warranted by Meech Static Eliminators Ltd to the original purchaser against defects in material and workmanship for one year after purchase. Should any malfunction occur, please return the bar directly to Meech Static Eliminators or your local distributor.
