A scrubber for removing pollutants from a gaseous medium, having a chamber with a plurality of spaced straight and curved baffles positioned to direct incoming dirty air over a water reservoir at velocities sufficiently high to enable the dirty air to entrain multitudes of water droplets. The water droplets are thoroughly mixed with the dirty air, and the solid pollutants in the air are thoroughly wetted. The wet solid pollutants, being relatively heavy, are deflected downward through the action of the baffles and reduced air velocities into the water reservoir. A constant-volume air control means interposed between the chamber and the source of polluted air, such as dirty air from an incinerator or the like, contains a primary air inlet duct and a secondary air inlet duct where the air through each duct is controlled by a damper. The dampers of the two ducts are coupled to operate complementary to each other to provide a constant air flow to the chamber for various flows of polluted air directed to the scrubber through the primary air inlet duct.
