Ionisers are useful in preventing electrostatic charge generation, Electro-static Discharge, Electro-static Attraction, as well as preventing equipment latch-up. Per ANSI/ESD S20.20 section 184.108.40.206. Protected Areas Requirement states: “Ionisation or other charge mitigating techniques shall be used at the workstation to neutralise electrostatic fields on all process essential insulators if the electrostatic field is considered a threat.” “Air ionisation can neutralise the static charge on insulated and isolated objects by producing separate charges in the molecules of the gases of the surrounding air. When an electrostatic charge is present on objects in the work environment, it will be neutralised by attracting opposite polarity charges from the ionised air.
Note that ionisation systems should not be used as a primary means of charge control on conductors or people.” (Reference: EN 61340-5-2:1 clause 5.2.9)
The 2 fan and 3 fan overhead Ionisers are a steady-state DC ioniser for use in ESD sensitive work areas. The specially designed fan modules create better coverage, consistent offset voltage (±5 Volts) and superior discharge times (< 3 seconds). The unit can be networked with others as an option.
