 air purifier electrostatic precipitator for air cleaner

An electrostatic precipitator (ESP) is a highly efficient filtration device that removes fine particles, like dust and smoke, from a flowing gas using the force of an induced electrostatic charge minimally impeding the flow of    through the unit.

In contrast to wet scrubbers    which apply energy directly to the flowing fluid medium, an ESP applies energy only to the particulate matter being collected and therefore is very efficient in its consumption of energy (in the form of electricity).

What is electrostatic precipitation and how does it work?

Two stage electrostatic precipitators are composed of two sections, a charging section and a collection section. 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.

Electronic air cleaners maintain a relatively high efficiency on particles in a range of .01 micron to 1 micron. Because of their inherently open cell design, electronic air cleaners create a low pressure drop that greatly minimizes fan horse power, and translates into energy savings as compared to other types of air cleaning systems. Lower fan horse power also means a quieter operation. The primary air filters are cleanable, an important factor in considering the on-going operational cost and disposal issues. The quality built electronic cells from Air Quality Engineering that are part of the air cleaner are designed to be dishwasher-safe.
