Trion® – Principles of Operation

The TRION electronic air cleaner is technically known as an Electrostatic Precipitator (ESP). An electrostatic precipitator (ESP) is a high efficient particulate collection device that removes particles from a flowing gas (such as air) using the force of an induced electrostatic charge. When gas that contains an aerosol (dust, mist) flows between the collecting plates and the discharge wires, the aerosol particles in the gas are charged by the ions. The Coulomb force caused by the electric field causes the charged particles to be collected on the collecting plates, and the gas is purified. For bacteria and virus that attached on particulates, such electrostatic power will sufficient to direct and immediate kill them all by “Carbonization”. Despite how strong, powerful or harmful of the bacteria and virus are, bacteria normally were structured from multiple cells and virus structured by single cell, their cell membrane (Protein) is very weak that easy be breakthrough and totally destroyed by electrostatic power.

Three major functional components comprise the air cleaner:
(1) Ionizing-collecting cells to ionize and collect airborne particulate matter
(2) Power supply(ies) to provide high voltage direct current to the ionizing-collecting cells
(3) Control operated wash system to automatically wash away the collected contaminant


The major advantage for Electrostatic Precipitator is its strong and entire purification efficiency to particulate, dust, bacteria, virus, smoke etc. with little air resistivity and without any replacement cost, its operation and maintenance are easy and cheap.
