An electrostatic air cleaner is a device that removes polluting particulates, thus purifying air. As an example, contaminated air carrying a particulate, with a mass of 3.15 109 kg, will first pass through a charging grid, removing an electron and charging the particulate with a +1 charge. These positive particulates are then removed by being attracted to the negative grid and remaining on the grid as the rest of the clean air passes through. Refer to the above diagram and information. The electric field between the charged grids is: O a. 1.2 104 V/m [up] O b. 1.3 106 V/m [up] ○ c. 1.2 10 V/m [down] O d. 1.3 106 V/m [down] Electrostatic Air Cleaner air flow 4.0 x 103 V 0.30 cm ++ +++ An electrostatic air cleaner is a device that removes polluting particulates, thus purifying air.
