There are two main types of laminar flow hood design – Vertical Laminar Flow and Horizontal Laminar Flow. Laminar flow benches use a HEPA (High-Efficiency Particulate Air) filtration system to clean the air. Commonly used in medical research laboratories, laminar flow benches are used to prevent contamination by reducing airborne dust, dirt, and particulates.
Deciding which flow hood design is best for your workspace, will depend on the level of protection required for the user, sample, and environment. The choice will also be determined by the specific needs and requirements of the workplace.
