The IZS4 family is SMC's 3rd generation of bar ionizers. Bar ionizers generate a curtain of static eliminating ions effective for a distance up to 2000mm / 6.5 ft. The family includes the standard IZS40 model, the IZS41 with feedback or auto balance sensor and rapid static neutralization, and the IZS42 with low amplitude ion generation for sensitive electronics. The IZS41 and 42 are remote control capable, and can be linked via cable for operation from a single power supply. Needle cartridges are easily removed without tools for cleaning or end-of-life replacement.
