Electrostatic Precipitator (ESP) Mist Eliminators

Industrial electrostatic air cleaners or ESP type mist eliminators provide healthy indoor air quality via the most efficient and consistent operation of any current mist collecting technology. Other forms of machine coolant oil mist filters include media filtration and centrifugal separation. All three technologies are used to collect smoke and metal working fluid mist, though electrostatic precipitators generally outperform the other two smoke and mist eliminator filtration methods.

Electrostatic Precipitation (ESP) Mist Eliminator Technology

by James Lee, Industrial Designer

Electrostatic precipitation, sometimes called ESP or electronic air cleaning, was invented in the early 1900s, has been widely used in smokestacks and was adapted for commercial, industrial and residential uses in the early 1970s. By the 21st century, developments in power supply, ionizing and general construction technology has made electrostatic precipitators the most desirable choice for oil smoke mist eliminators.

As the air stream passes through the electronic mist eliminator, it goes though an ionizing section followed by a collecting section. The ionizer applies an electrical charge to any airborne contamination that floats through it. Smoke, mist and particles are now electrically charged. In the next section, the air stream passes through series of oppositely charged collection plates. The air pollution is attracted to the collection plates and sticks to them. Once on the plate, material takes on the electrical charge of the plate, attracting more airborne contaminants to stick to them. Because the filtration device uses plates instead of woven filter media, the air stream can easily pass through with minimal resistance.

Unlike media filtration, an ESP mist eliminator is efficient and inexpensive to maintain. Once media filters become fully loaded, they must be thrown away and replaced with new ones. When collecting mist, electrostatic collection plates often need no maintenance. For oil and synthetic coolant mist, ESP mist eliminators continuously collect and drain fluid which also protects and lubricated the cells. For the rare applications that do load the cells, collection plates should be washed and reused, never thrown away. Most collection plates are designed for easy maintenance, switching out a dirty collection cell typically takes three to five minutes.

Also, ESP mist eliminators use very little electricity. There is only one moving part, the fan. And it only requires enough power to move air between plates. Unlike media filtration, electrostatic precipitation creates almost no static pressure for the fan to overcome. Between the fan, ionizer and collection cell, a typical ESP mist collector uses about the same power as two or three light bulbs.

A few oil smoke mist eliminator applications involve contamination that does not work well with electrostatic precipitation. If you are not sure about your application, feel free to call 1-877-688-2703 to talk to one of the specialists from BPA. Whenever possible, I suggest you choose an electrostatic mist eliminator. ESP is far more reliable, efficient and more cost effective than centrifugal mist collectors or media based coolant mist eliminators.
