Fan Filter Unit(FFU)
FFU, short for Fan Filter Unit, is an air purification device that integrates a fan and a high-efficiency filter into a single unit. FFUs are typically installed in the ceiling grid of cleanrooms, serving as terminal air supply units that deliver high-efficiency filtered clean air into the cleanroom environment.
The FFU is one of the core equipment components in modern cleanrooms, widely used in industries with strict air cleanliness requirements, including pharmaceuticals, biotechnology, semiconductor manufacturing, electronics production, hospitals, and food processing.
