A cleanroom is a controlled environment that is designed to maintain a low level of particulate contamination and other airborne pollutants. Cleanroom systems are typically used in industries such as pharmaceuticals, biotechnology, and electronics manufacturing, where even tiny particles of dust or other contaminants can cause significant damage to products and processes. A cleanroom system consists of a variety of specialized components such as air filters, air handlers, HEPA filters, positive pressure systems, and specialized flooring and wall panels. The cleanroom's level of cleanliness is determined by the number of particles per cubic meter of air, which is measured using a particle counter. The level of cleanliness required will vary depending on the specific application, with some cleanrooms requiring a very high level of cleanliness and others requiring only a low level. The design and implementation of a cleanroom system must take into account a range of factors, including the required level of cleanliness, the size and shape of the room, and the specific needs of the application.
