What is an FFU Laminar Flow Air Supply Unit?
The FFU (Fan Filter Unit) laminar flow air supply unit is a modular air purification device widely used in cleanrooms, clean workstations, clean production lines, modular cleanrooms, and laminar flow hoods. Its working principle involves drawing air in through a top-mounted fan, filtering it through a high-efficiency filter, and then delivering clean air across the entire outlet surface at a stable speed of 0.45 m/s ±20%.
