A custom fume hood is a specialized ventilation system that is designed to capture and contain hazardous fumes, vapors, and dust particles in a laboratory or industrial setting. It is typically made of stainless steel or other non-corrosive materials and is designed to provide a safe working environment for personnel working with hazardous materials. The hood is typically equipped with a fan or blower that pulls air through the hood and exhausts it to the outside. The hood also typically has a sash that can be opened and closed to control the amount of air entering the hood. The hood is designed to keep personnel safe from hazardous fumes and particles, and to keep the laboratory or industrial environment free of contaminants. Custom fume hoods are designed to meet the specific needs of the laboratory or industrial environment, and can be customized to meet the specific requirements of the application.
