The charging section uses ionizer wires to impart a positive charge to the incoming smoke, fume and dust particles. The charged particles are then drawn into a secondary electric field where they are collected on a series of metal plates. Then, the electrostatic precipitators re-circulate clean air into the general airstream. Over time, the collector section metal plates become…
