Introduction to FFU
FFU, or Fan Filter Unit, is a crucial equipment in cleanroom technology. It is a self – contained, fan – powered module that combines a fan and a high – efficiency particulate air (HEPA) or ultra – low penetration air (ULPA) filter. FFUs are widely used in industries such as semiconductor manufacturing, pharmaceutical production, biotechnology, and food processing, where maintaining a clean and controlled environment is essential. They can effectively remove dust, bacteria, and other contaminants from the air, providing a clean airflow to the cleanroom area. FFU
