Stable ion-producing performance contributes to a longer maintenance cycle, which has been improved to one month or longer in Panasonic ER-VS. The discharge needle tip’s spherical shape enables more stable ion production while making it less likely that the shape of the tip will change over time as a result of electrical discharge. In addition to eight standard nozzle types, including shower and tube nozzles, We offers a range of differently shaped nozzles (including made-to-order models). The main unit is merely 109 x 27 x 28 mm 4.291 x 1.063 x1.102 in, so it can easily be combined with other devices and also be installed as an add-on. Furthermore, the highvoltage power supply is built-in, so no extra space is required except for the ionizer itself. The adoption of high-frequency AC method allows extremely stable ion balance to be achieved. Because the ion balance is not affected by the pressure of air supplied or by the setup distance, no troublesome adjustments are required after setup. A full range of functions have been provided with full consideration given to ease of use in the workplace. No separate controller is needed. The discharge needle does not protrude from the main unit, so it cannot be touched by accident. Furthermore, no leaks can occur when it is brought close to metallic objects.
