A cleanroom is an environment that is designed, built and operated to provide cleanliness, control and/or isolation for certain processes. The purpose of a cleanroom is to protect the product or the process from contamination, to restrict access to the product or process and to contain any hazards located in the cleanroom. Cleanroom technology is commonly used in manufacturing and research and development, in several industries, including nanotechnology, defense, microelectronics, pharmaceuticals, biotechnology, and medical devices. Once you’ve made the decision to build a cleanroom, what happens next? Your individual process needs and variables must be examined thoroughly. Cleanroom Standards Cleanroom technology standards ensure that cleanrooms have little to no contamination, which is anything that could corrupt the process or make the product impure. Contamination is defined by a specified number of certain size particles per cubic foot of air. The particle size measured in cleanrooms are typically 0.5 microns (µm) or larger in diameter. For perspective, a human hair is 60–80 microns wide and outside air has about 35,000,000 0.5µm and larger-sized particles sized per cubic foot of air. Cleanroom Classifications Cleanrooms are defined by their level of cleanliness; more specifically, the amount of particles found in the air. Cleanroom classifications include a class 1 cleanroom or ISO class 3, which by today’s standard, typically has one .5 micron sized particle per cubic foot of air, for which a typical HEPA is rated. Cleanrooms range up to class 100,000 or ISO class 8, which includes up to 100,000 particles at .5 microns. The Classes Contaminant Prevention Levels Certification Energy Expended Mechanical Systems There are three primary mechanical systems for cleanrooms: Ducted supply and ducted return This system, as named, supplies the air directly to the HEPA filters through a ducted system and back from the returns to the air handler through duct work.
