The BFU fan filter unit, which uses the latest technology in the United States, is a ceiling unit with a fan inside, used for turbulent flow and laminar flow clean room. BFU fan filter unit is one of the quietest and best-priced units on the market.


FFU is an abbreviation for English, the full name is Fan Filter Units, which means "fan filter unit (unit)". That is, a fan and a filter (HEPA) or Ultra High Efficiency Filter (ULPA) are combined to form a self-powered end purification device. Specifically, it is a self-contained, modular end air supply with filtering efficiency. The fan draws in air from the top of the FFU and filters it through HEPA. The filtered clean air is evenly sent out over the entire wind surface at a wind speed of 0.45 m/s ± 20%.
