How Electrostatic Filtration Works

Electronic air cleaning systems use one or more permanent electronic collector cells or filters featuring electrostatic precipitation technology to collect and remove smoke, grease and other harmful contaminants in commercial kitchen hood exhaust.

An electronic collector cell is composed of an ionizing or charging section and a collection section. Incoming contaminant particles pass through an intense ionization field in the charging section. The ionization causes the particles to lose electrons and acquire a positive electrical charge.

In the collection section, positively charged metal plates or fins repel the positively charged particles, and alternating grounded fins attract the positively charged particles.

Contaminants remain trapped on the grounded fins until the collector cell is washed.
