What is the purpose of the airfoil in a fume hood?

The airfoil in a fume hood plays a crucial role in maintaining proper air circulation. Its design helps to direct the airflow efficiently across the working area, ensuring that any hazardous fumes or vapors are effectively captured and removed from the laboratory environment. By optimizing the flow of air, the airfoil minimizes turbulence and enhances the fume hood's ability to protect the user from exposure to potentially dangerous chemicals. This function is vital for maintaining a safe working environment and ensuring that the fume hood operates effectively during experiments.
