The upper part of the FFU fan is the fan module, and the lower part is the filter. According to the cleanliness requirements, the filter can be a different level of high-efficiency or ultra-high-efficiency filter, providing clean air for the clean room. The fan module not only needs to overcome the resistance of the high-efficiency filter at the bottom of the FFU, but also needs to overcome the resistance of all the components of the entire circulation air path, thereby maintaining the set operating air velocity.
The FFU fan system has the characteristics of simple design and construction, flexible air speed adjustment, and ease of changing the clean area. Therefore, it has become one of the popular system forms in industrial clean room.
The design of the FFU fan unit is flexible as a whole, and it is convenient to be used in combination with special type ceiling frameworks and other suitable frameworks. When the filter adopts a knife-edge type frame, this unit can also be used for liquid tank sealed ceiling frameworks. According to the design specifications, it can easily cooperate with any ceiling framework to meet the cleanliness level requirements. The outer frame can be made of aluminum or stainless steel, each with its own characteristics.
By using this unit, high-quality air can be delivered to the clean room, and the air circulation is good. It is suitable for manufacturers of semiconductors, electronics, flat panel displays, and disk drives, as well as optical, biological industries and other places with strict control requirements for air pollution.
