Passive Systems

Passive ionisers are self-ionising products which can be used to achieve a crude neutralisation in order to reduce or avoid the occurrence of sparks and disturbance of personnel especially through electric shocks – they can be a quick and low priced solution for this matter.

Nevertheless, there will always be residual charges left and thus do not solve production problems (dust adhesion/attraction, adhering parts, floating sheets) to the satisfaction: an active discharge remains indispensable. It is common to use passive ionisers preceding active ionisers/electrodes as combinations: the passive systems already reduce the bulk of the charge while the active electrode neutralises the residual charge with more ease.

We included the passive ionisers due to follwoing reasons in our portfolio:

  • Best possible discharge performance for passive systems:E101/102 E102/202 Anti-static brushes, F406/409 Tape Brush
  • High speed and/or high charges: E101/102 E102/202 Anti-Static Brushes
  • Low in loss of fibres and space-saving: F850 Anti-Static Cord
  • Easy installation: F406/409 Tape Brush
  • Explosion-hazarduous areas/environments: EX101 Specific Anti-Static Brush
  • Best price for crude neutralisation: F801 Anti-Static Tinsel

You can find E201, F850 and F801 in our Online Shop and buy them directly – don’t hesitate to get advice.

The passive ionisers do not need to touch the surface to be discharged directly: the electrical field of the charged surface itself is ionising the air in the gap between charged surface and fibre tips and thus brings the (positive or negative) charge automatically to neutralisation. In average a gap/distance of 3 to 5 mm is desirable. This can not always be achieved with Tinsel, because it is not possible to tighten it over the surface and only accepts tensile loads of 10 kg max.

If the fibres of the passive system can touch the charged part/object, the charge can be conducted even more efficiently – for metallised foil or paper even a must. However, for fast-moving material it is often not possible or desirable. Nevertheless, all passive systems mandatorily need to be grounded for a discharge through ionisation and/or contact to take place.

Please ensure, especially in the case of ant-static brushes, that opposite to the ioniser no metal parts are located, otherwise the desired ionising effect is not or only partially taking place.
