The operations in a laboratory setup require different types of furniture that range from heavy duty workbenches, utility cards and lab cabinets to laminar flow workstations and chemical fume hoods. The air has a high chance of becoming polluted as it is not unusual for different types of experiments and industrial work to release toxic chemical vapors, aerosols, and suspended particles. Thus, it is important to keep the lab environment as clean as possible, and a chemical fume hood contributes to this purpose.
A chemical fume hood is basically enclosedequipmentthat is designed to draw air inward for filtration purposes. The main function of the exhaust is to control the presence of hazardous substances in the air by drawing in air with the help of mechanical ventilation.
