Laminar air flow is vital in pharmaceuticals for particle control and sterile production. Cleanrooms use HEPA filters, employing laminar or turbulent air flow for particle-free air. Uniform laminar air flow minimizes air mixing. In contamination-sensitive spots, like dust-free hoods, it also maintains a clean zone. Laminar Flow Cabinets ensure particle-free workspaces, using filtered air and positive pressure to prevent contamination.
