Leading Cleanroom Design Manufacturers

Technological advances and the development of complex instrumentation have necessitated purified environments to avoid contaminating components and parts from atmospheric particles and bacteria. Clean rooms were developed in the middle of the 20th Century to create the ideal tool for providing conditions for the production, manufacture, and fabrication of modern technological tools and instruments.

The term clean room refers to a specially engineered and designed environment that has been cleansed of dust, dirt, microbes, and other contaminating particles. To be classified as a clean room, specific standards and conditions must be met, as stipulated by the United States Governments Federal Standards 209 (FED-STD-209E) and the International Organizations for Standardization (ISO).

The description of the standards of the ISO and Federal Standard 209 clearly and concisely defines the conditions a clean room must meet to be classified as a clean room. Adhering to the qualifications is the initial step in the process, followed by determining what classification a clean room meets.

Although the ISO and Federal Standard 209 intend to define the class of a clean room, each organization approaches the issue using a different classification method. For the ISO, clean rooms are classified using a numbering system, beginning with ISO 1 for the strictest compliance with clean room standards and continuing to ISO 9. Federal Standard 209 was published by the Institute of Environmental Sciences and Technology (IEST) in 1963 and was updated in 1992. Its numbering system begins with class 1 (ISO 3) as the most restricted and continues to class 100000.

The designing of a clean room begins with determining what classification is necessary. The primary factor in deciding is based on the size and quantity of particulate matter allowed in the air, which is essential for defining a clean room's classification.

Federal Standard 209 Air Classification System

The particles measured in a clean room are far smaller and more minute than the types of pollen, dust, and dirt that can be seen with the naked eye. Clean room particles are measured in micrometers, or one-thousandth of a millimeter, and referred to as a micron (µ).

Definition of a Micron

The US FED STD 209E standard system rates clean rooms based on the number of 0.5-micron particulates present per cubic foot in an enclosure. The particulate volume number decides the classification number assigned to a clean room. For example, Class 1 clean rooms have no more than one 0.5 micron particle per cubic foot. To achieve this low level of contamination, Class 1 clean room designs must have high-efficiency particulate air (HEPA) filters working in concert with other decontamination equipment.

As the class numbers increase, so does the acceptable level of particulate presence. For example, Class 10000 clean rooms contain no more than 10,000 0.5 micron sized particles per cubic foot. By comparison, the normal unfiltered air we breathe would be Class 1,000,000.

The lower the class number, the more likely the clean room has hard walls with a complex filtration and personnel decontamination system. Higher-class clean rooms, such as modular and portable ones, can be less permanent. They provide basic protection and can be moved easily and disassembled without difficulty.

The design and structure of a clean room dictate the kinds of operations for which it can be used. This is also represented through the garments workers are permitted to wear. For example, class 1 clean rooms require employees to wear a bunny suit covering them from head to toe with a mask and synthetic gloves. In a Class 10000 clean rooms, workers can wear their own clothes but must have their hair, feet, hands, and faces covered. Additionally, class 1 clean rooms are small and limited to allow for better air supply control, while class 10000 clean rooms can be very large like classrooms.

Elements of a Clean Room

Three basic principles are considered when planning and designing a clean room. The first of those considerations is the quality of the air, which is the determining factor regarding a clean room's classification. Next is the size and number of surfaces of a clean room and the type of equipment used. The final component, and the one that supplies the most contamination, is the number of workers.

Air Filtration

The key element when defining a clean room is its quality of air. Controlling fresh air flow is simple since it involves passing a stream of air through a high-efficiency particulate air (HEPA) filtration system. The challenge is how to maintain that system without the clean room being contaminated. This aspect of the design process is the key to a high-performance clean room.

Each classification of clean rooms measures the air change rate (ACR), determined by how quickly the air in a clean room is replaced by clean filtered air. The ACR is the number of air changes per hour, with lower-class clean rooms having an ACR measured in changes per second. Additionally, the speed of the change is measured in feet per minute.

HEPA Air Filtration

Knowing what atmosphere the industry requires is necessary when planning a clean room. Particle size and the number of particles in a cubic foot or meter must be carefully assessed regarding the product being tested or fabricated.

Clean Room Structure

Once the air filtration and cleanliness have been established, the next step is to design the walls, ceiling, floor, vents, and entryways for a clean room. Wall panels are made of resilient materials that are tightly secured. Ceilings have a metal hanging grid where tiles are securely placed. Finally, vents can be located on the floor or walls for easy airflow.

Cleanroom Construction

Personnel

The final element in clean room planning is the people who will work in it. Air control, clean walls and ceilings, and the seal of a clean room are static and seldom change. However, the personnel is constantly changing and carries a wide range of contaminants and bacteria, which must be monitored and controlled through body coverings, masks, and decontamination doors and pass thrus. The classification of a clean room determines the type of hygiene clean room staff must follow.

Selecting the Right Clean Room Design Company

For the most productive outcome when purchasing a clean room design from a clean room design company, it is important to compare several businesses using our directory of clean room design companies. Each clean room design company has a business profile page that highlights their areas of expertise and capabilities, along with a contact form to directly communicate with them for more information or to request a quote. Review each clean room design business using our patented website previewer to get a better understanding of what each company specializes in. Then, use our simple RFQ form to contact multiple clean room design businesses with the same form.
