Class 100 Clean Rooms

Class 100 Clean Rooms

Class 100 clean rooms are the third highest classification in Federal Standard 209 standards and never exceed 100 particles per cubic foot. The airborne cleanliness classes in clean rooms and zones name their classes after the maximum number of particles allowed in the rooms at one time. Class 100 follows classes 1 and 10, which are used in production labs for electronic integrated circuits. Class 100's ISO standard equivalent is ISO 5. They are used in the medical and computer manufacturing industry in labs for applications such as medical implants and hard drive production or repair. Clean rooms are used where air is continuously filtered so tiny particles in the air don't damage highly sensitive technologies.

The panel or wall materials in class 100 clean rooms are often made of white acrylic, steel or stainless steel, aluminum or polycarbonate. Bunny suits are provided for people working in clean rooms so their skin and hair particles don't enter the room. This class of clean rooms can be any of the 3 types-ball room, which are large and open rooms that are parts of the actual building, modular, which are temporary and small rooms within a room, and soft wall, where the walls are made of tightly stretched or free-hanging fabric. They may range in size from huge open spaces to tiny chambers. Temperature control and electrostatic discharge control are also possible in this class of clean rooms.
