Electrostatic Precipitator is a device that can remove airborne particles with high-efficiency and low-pressure drop. It can filter particles of sizes from 0.01 microns to 100 microns, thus widely used filter particulates like dust, oil mist, and cooking fumes. A typical application is to purify cooking fume from commercial kitchens of restaurants, delis, company canteen, hospitals, schools, and sport & entertainment complexes. It is also used for coffee roasting, CNC machine shops and Cold Heading, cleaning room, smoking room, and other HVAC air purification.
When dirty air (fume or smoke) enters the electrostatic precipitator, the pollutant particles pass through a high intensity electrical field (IONIZER) which imparts an electrical charge to the particles, which range in size from 0.01 micron to 10 microns. The charged particles pass through a series of parallelized charged collector plates. Particles are repelled by plates with the same polarity, but attracted and collected by plates with opposite polarity. The pollutants particles collected are held in these plates and liquid pollutants (like oil in cooking fume) can drain down to collection tray in the bottom. Then you get clean air.
