Conductive wheel, esd wheel, anti-static wheel

Dissipates static charge build-up away from the chair and the worker. Used in surgical suites, electronic component assembly lines, and clean rooms. In addition to being made of static-dissipating materials, they often have some sort of metal connection (wire loop or chain) with the ground. Must be kept very clean to function properly. A layer of dust will negate the static-dissipating effect. Only available in soft tread for hard-floor applications.
