Abstract
Methods and apparatus for cleaning contaminant byproducts off of ionizing wire electrodes in ionizing blowers are disclosed. Disclosed apparatus include a housing with a gas-flow channel, an stationary ionizing wire, and a rotatable frame with supports for resiliently supporting the stationary ionizing wire within the channel. The ionizing wire produces charge carriers and has a surface that develops a layer of contaminant byproducts when an ionizing signal is applied thereto. The frame is rotatably mounted such that the supports clean the layer of contaminant byproducts off of the surface of the ionizing wire when the frame is rotated. Disclosed methods include providing an ionizing signal to the ionizing wire to thereby produce charge carriers and rotating the frame relative to the housing to thereby clean contaminant byproducts off of the ionizing wire.
