r,air filters and a control unit make the FFU become an independent air filtration device,not only can be used alonely,but also be used at scale.

Fan filter units are installed at the ceiling, as clean air flow diffusers for clean rooms. They can make the clean room stay at a positive static pressure status. As a laminar flow diffuser, the FFU pushes the air from ceiling to floor unidirectionally. This is the most efficient mode for modern cleanrooms to quickly clean the air, by squeezing down the original air to return air grilles.
