Abstract

A pollutant separator having a cooling coil and a filter includes a scrubber device. The scrubber has a tube with holes in the walls thereof for the passage of fluid to and from a closed collection chamber. A series of spring biased balls within the tube serve as scrubber elements. Extending around part of the outside of the tube is a slidable spring-biased ring valve having a shoulder on which fluid pressure is exerted through a passage extending from inside the tube. The ring valve slides over some of the tube holes causing fluctuations in pressure within the scrubber unit to enhance vibratory, scrubbing motion of the balls contained therein. PAC BACKGROUND OF THE INVENTION This is a continuation-in-part of my copending application, Ser. No. 764,707, filed Feb. 1, 1977 now abandoned, which is in turn a continuation of my abandoned application, Ser.
