A Class 100 cleanroom, as a sealed production facility with relatively low levels of contaminants, can provide an optimal working environment for many specialized products. Such manufacturing facilities are categorized into several common cleanliness classes, including Class 10, Class 100, Class 1,000, and Class 10,000. Below, taking the Class 100 cleanroom as an example, we will explore the specific industries and applications where this level of cleanliness is employed.
So, what exactly is a Class 100 cleanroom? A Class 100 cleanroom, also known as a Class A cleanroom, is simply a cleanroom that meets the Class 100 cleanliness standard. Specifically, its design and construction must ensure that the concentration of airborne particulates in the room is maintained within a strict range: no more than 3,500 particles per cubic meter with a size of 0.5 microns or larger.
Class 100 cleanrooms have strict regulations for both cleanliness and sterility testing; however, they are not truly sterile environments. A small amount of airborne particulates and microorganisms may still be present, but their low concentration does not adversely affect production or operational activities. Class 100 cleanrooms are typically used in the medical field—for example, in the manufacture of implantable medical devices, in clinical settings, and for the isolation and treatment of patients with bacterial infections. In addition, they find applications in industry, such as the production of high‑precision optoelectronic components and other cutting‑edge products requiring stringent accuracy.
In a Class 100 cleanroom, the air‑handling system employs vertical laminar flow with side supply, meaning the airflow moves in a streamlined, parallel pattern at a uniform cross‑sectional velocity. Before entering the room, the supplied air first passes through a primary‑efficiency filter to remove coarse particulates and suspended dust. After this preliminary filtration, the air is further purified by a secondary filter. This two‑stage filtration process yields exceptionally clean air, and it also helps extend the service life of the filters. Since filters are relatively expensive, frequent replacement can become costly and economically impractical.
Under the pressure of airflow, the gas meets the cleanliness requirements specified by the filter. Since the air in the Class 100 cleanroom circulates vertically and is uniformly filtered, both the exhaust and ventilation systems remain free of particulate matter, thereby preventing secondary contamination.
The construction and renovation of a Class 100 cleanroom is a highly complex and specialized undertaking. To ensure the facility meets the relevant standards, it is essential to engage a reputable, technically proficient cleanroom engineering firm to undertake the project.
That concludes our analysis of this article. By now, you should have a solid understanding of the applications of Class 100 cleanrooms.
