WebBSCs are designed to provide both a clean work environment and protection for employees who work with biological hazards. BSCs use vertical laminar airflow to create a barrier to airborne particles, such as microorganisms. They use High Efficiency Particulate Air (HEPA) filters to clean air going into the work area and out to the environment. Web1 dec. 2024 · From Fig. 19, it can be observed that there were longitudinal and lateral inward airflow regions below the nose and tail and between the rotors respectively. This inward flow had been measured in outwash velocity measurements by the rakes and is due to the upward fountain flow between the tandem rotors which creates suction on the …
