Clean Room Design & Construction
-
Types of Designs
-
Clean rooms can be constructed large and permanent or small and portable. Modular enclosures come in all sizes and are assembled in manufacturing plants using materials that protect against airborne contaminants, temperature variance, noise and ultraviolet light. Some materials are anti-static vinyl, aluminum sheets, clear acrylic and rigid ABS. A modular clean room can be added on to without interference of contamination. Other different types of designs include soft wall, portable, hard wall, self-contained and mini-micro clean rooms.
Airflow
-
Two separate air flow principles can be used in clean rooms. A laminar air flow system blows a constant stream of HEPA or ULPA filtered air downward toward other filters located on the walls. Stainless-steel hoods are further fitted with air flow filters to keep incoming air clean from particles. A turbulent air flow system uses velocity filters of HEPA or ULPA and laminar air flow hoods, continuously moving the air in different directions. The air ultimately arrives on the floor, where filters capture any particles.
Scope of Work
-
The scope of work in planning and implementing a clean room is rigorous; you must apply and receive validation from appropriate regulatory authorities before the design and construction can begin. Sizing of equipment, utilities to service, flow diagrams that consider the placement of machines, and people and HVAC zoning are a few factors to consider in designing an approved clean room. Depending on the type of work to be done, you will need to meet clean room standards.
Users of Clean Rooms
-
Machine Medical buildings and pharmaceutical-testing facilities are not the only companies that require an environment free from contaminants. Manufacturing plants, testing facilities, scientific research and the microelectronics industry are other examples of businesses that require a clean-room atmosphere. Dust and pollutant particles can have an adverse affect on product evaluation and testing.
Entry Rooms
-
Air shower Entering a clean room is also a concern to address in the designing and building. Particles of dirt, pollution and viruses can stick to clothing, skin and shoes. These contaminants need to be removed before entering a secured clean room. Pass through cabinets are small rooms that are attached directly onto the clean room where products can be delivered. An airlock, called a walk through chamber air shower, is a method used to air spray an individual before entering the clean room. One or both of these rooms may be necessary in a design.
