ABSTRACT:
Ionizing gas gun for ultra-clean static neutralization comprises a plastic nozzle enclosing positive and negative ion discharge electrodes and means for blowing a gas, such as air or nitrogen therethrough. A trigger actuates both the release of gas and application of positive and negative high voltage to the respective discharge electrodes, including delay circuitry for suspending discontinuance of the positive high voltage to its electrode for a momentary period subsequent to discontinuance of the negative high voltage when the gas is cut off in compensation of a slight preponderance of negative ion emission otherwise effected at cut-off. Venturi ports at the nozzle tip draw air over the discharge electrodes for admixing with higher mobility nitrogen ions when nitrogen rather than air is employed as the blowing medium. A changeable filter insures cleanliness, including monitoring means to indicate clogged or ruptured filter conditions or improper installation.
