Among the laboratory ventilation equipment, the all-steel fume hood is a very important equipment. It is an important equipment to protect laboratory operators from hazardous chemical agents. It is also a need to protect and improve the operator environment and ensure product and environmental safety. It is an integral part of laboratory design. In order to prevent laboratory workers from inhaling or ingesting some harmful, pathogenic or unknown harmful chemicals, the laboratory should have good ventilation. In order to prevent the absorption of some vapors, gases and particles (smoke, soot, dust and aerosols), pollutants must be removed using all-steel fume hoods, fume hoods or local ventilation.
