Installation

The 914EX 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. 
These precautions will maximise the unit’s ionisation capability.  

Good results can be achieved at distances up to 100mm but as the distance from the 
object increases, the speed of charge neutralisation will decrease.

A typical installation distance is 40mm from the target surface. This gives exellent 
performance at high web or product speeds, whilest avoiding possible damage from 
web breaks or product mis-feeds. Very fast webs may require the bar to be as close 
as 25mm to the web.

Correct positioning of the bar(s) is vital to efficient operation. The following diagrams 

show the correct installation procedures:

1. The optimal distance from material to be neutralised.
