A cyclonic separator for particles suspended in the flow of an air stream. The separator comprises first and second spiral baffles adapted for mating engagement one within the other for imparting cyclonic flow to the air stream for collecting the particles from cyclonic motion thereof. The baffles are oriented with the first baffle rotated relative to the second baffle to therein form a flow path therebetween. The flow path between the baffles has in it a reversing, oppositely directed concentric spiral passage which carries the particles in a first spiral direction and then in a second opposite spiral direction. Each inner terminal end of the first baffle, or each outer terminal end of the second baffle, or both, may include an arcuate region of sharply increasing curvature adapted for collecting strayed paint particles and solvent droplets. The first and the second spiral baffles as described above may also be made from electrically conductive material and each is being held electrically insulated from the other for the application of electric potentials of opposite polarity thereto.
