Pulsed DC ionizers utilize separate power supplies to generate positive and negative voltages and has its own dedicated emitters. The power supply alternates between positive and negative, but usually at a lower frequency than AC units. In this way, ion recombination is reduced and performance in many instances is increased. Pulsed DC ionizers have the ability to work at greater distances without the use of air flow, which improves operator comfort without compromising performance. This technology is also applied in ionizing blowers, ionizing bars, and blow-off gun devices. In addition, it has wide application for controlling static charge in room systems, on work surfaces and flow hoods, and in equipment at the point of use.
