Electrostatic Filter

An electrostatic filter has two main sections as shown in Fig. 12.5.The first section is the ionizing section; it consists of a series of fine wires charged to a voltage of up to 13 kV, placed alternately with earthed rods.This sets up a corona discharge, and as the airborne particles pass through the ionizing field, they receive a positive electrostatic charge.
