An electrostatic precipitator having a rotor supported for rotation within a housing containing inlet and outlet openings adjacent the opposite ends thereof. The rotor is formed by a plurality of ringlike collector plates which are fixedly connected in parallel but axially spaced relationship. One end of the rotor, which is closed by a support plate, is disposed adjacent the outlet opening. The collector plates are alternately of opposite charge to create electrostatic fields therebetween to remove ionized particles from the gas which flows radially outwardly between the plates during rotation of the rotor. The collector plates have aligned central openings which decrease in diameter towards the closed end of the rotor. The outside diameter of the collector plates also decrease in diameter towards the closed end of the rotor, whereby the collector plates all substantially equal surface areas acted upon by the electrostatic field. An ionizing device is disposed across the inlet opening for ionizing the foreign particles entrained in the gaseous stream which flows through the inlet opening into the rotor.
