• High voltage power supply– transforms & rectifies 115/230 Vac input to dual output of
(+)12.0 / 6.0 kVdc• Ionizer - collector cell
– powered by the kVdc from the high voltage power supply– 1st stage: ionizer (+) 12.0 kVdc charges particles– 2nd stage: collector (+) 6.0 kVdc charges alternate plates
repel the (+) particles, grounded plates attract and retain the particles
