How Does Electrostatic Air Cleaning Technology Work?
Have you ever wondered how your electrostatic precipitator, also known as an electrostatic air cleaner, works? The science behind this technology has been around for over a century and continues to be one of the most effective ways to remove airborne contaminants such as smoke, oil mist, grease, dust, and other fine particles.
The concept of electrostatic precipitation was first introduced in 1824 by M. Hohlfeld, a mathematics teacher in Leipzig, Germany, who described the process of removing smoke particles using electricity. In 1908, American chemist Frederick Gardner Cottrell developed the first successful commercial electrostatic precipitator process. Since then, this technology has continued to evolve and is now used in many residential, commercial, and industrial applications.
Today, electrostatic air cleaners are used in a variety of industries to help improve air quality and control airborne contaminants. Manufacturers such as SmogHog®, Tri-Mist®, MistBuster®, Trion®, Aerocology®, and many others have developed advanced electrostatic filtration systems designed for applications including restaurants, manufacturing facilities, welding operations, and other environments where smoke, oil mist, and particulate control are needed.
Electrostatic air cleaners are capable of capturing particles as small as .01 microns, making them one of the most efficient and effective technologies available for removing airborne contaminants.
How Does an Electrostatic Air Cleaner Work?
An electrostatic precipitator works by applying energy directly to the particles being collected while allowing air to continue flowing through the system with minimal resistance. The process happens in two main stages: ionization and collection.
First, contaminated air enters the air cleaner and passes through the ionizer section. This section uses high-voltage ionizing wires to create an electrical field that gives smoke, oil mist, dust, and other airborne particles an electrical charge.
After being charged, the particles move into the collection cell. The collection cell contains a series of parallel plates, where alternating plates are charged and grounded. This creates an electrical attraction that pulls the charged particles out of the airstream and collects them on the plates.
A simple example of this process is rubbing a balloon against your hair and then watching it stick to a wall. The balloon becomes electrically charged and attracts another surface. Electrostatic air cleaners use this same basic principle on a much larger scale to capture contaminants from the air.
Keeping Your Electrostatic Air Cleaner Operating Efficiently
Like any piece of equipment, electrostatic air cleaners require regular maintenance to perform at their best. Over time, contaminants collected on the cells can reduce efficiency if they are not properly cleaned.
