Abstract

An electrostatic precipitator for air cleaning wherein the air passes through in two steps: first passing through a charging portion and next through a separation portion. The charging portion includes wires positioned parallel to and between parallel metal sheets, the wires having an electric potential other than that of the metal sheets. The separation portion includes plural parallel metal sheets, each of which has an electric potential other than that of adjacent metal sheets. The charging portion includes two or more wires between each pair of metal sheets, and the metal sheets of the charging portion extend through and constitute some of the metal sheets of the separation portion, between which are disposed addition metal sheets of an odd number.
