Abstract: A laminar flow work table has a perforated work surface positioned and supported a predetermined distance above a floor surface. The perforated work surface is divided into sections. Each section communicates with a separate duct communicating with the perforations in its respective section and extending to a common exhaust manifold connected with a return duct in a ventilation system where the table is situated. Each section of the work surface is ventilated by drawing fluid through the perforations into the ductwork and out to the return duct through the common manifold. Each duct has a baffle which controls the flow of fluid in its respective duct which permits the ventilation in various parts of the work table to be balanced. This arrangement permits the work table to be adequately and uniformly ventilated so that noxious fluids may be effectively removed from the vicinity of the work table so that a worker is not exposed to dangerous, unpleasant, or unhealthful conditions.
