Our laminar flow hoods provide the best clean air in a restricted area such as a work table and eliminate up to the minutest microns of dust particles. These are available in two basic types–the horizontal type in which the laminar air flow is horizontal and the vertical type in which positive air pressure is preserved in the clean air space by decreasing the air outlet. They are made of high quality welded steel or white laminate block/commercial playboard. All of them are tested for efficiency at our factory before shipment. Prices will vary according to product specifications.
