Advantage of clean room with FFU:
The construction period can be shortened
The degree of cleanness from class 1 to class 1000 can be set and the degree of cleanness can be set at each area
Because the back in the ceiling is a low-pressure, the potential of the leakage is low
Bay method or through the wall method is possible by the arrangement of layout of FFU
The velocity of the air flow can be set at each area
Flexible increase or change of the clean room is possible by the arrangement of FFU
