A discrete pod gas scrubber system for removing contaminants from the air of a work area, such as a paint spray booth. Each scrubber pod includes an inlet section having opposed converging planar walls and side walls, an intermediate section having opposed diverging walls and side walls communicating with the inlet section through a reduced diameter venturi, and an outlet section having a bottom wall perpendicular to the longitudinal axis of the scrubber pod, a diverging top wall and an end wall. The end wall includes an orifice opening and orifice plates for adjusting the orifice opening and the combined lengths of the aligned scrubber pods are between fifty and ninety percent of the total length of the scrubber system, more preferably between sixty percent and eighty five percent of the total length. The scrubber system of this invention significantly reduces the noise generated in the work area normally located above the gas scrubber system.
