A canopy hood is a type of ventilation hood designed to capture heat, smoke, fumes, and airborne contaminants rising from equipment or industrial processes. It is usually installed above machines, chemical tanks, cooking equipment, welding stations, or production lines where fumes and vapors naturally move upward. The canopy hood works by collecting these rising pollutants and directing them into a ducting system connected to an exhaust fan or air pollution control device such as a scrubber or fume absorber. Canopy hoods are widely used in industrial plants, commercial kitchens, laboratories, chemical processing units, and manufacturing facilities. Their open design allows them to cover a large area, making them suitable for capturing contaminants generated from multiple sources. By effectively collecting and removing airborne pollutants, canopy hoods help maintain a clean and safe working environment and improve overall air quality in the workplace.
