Companies across various sectors are eager to construct cleanrooms or otherwise controlled environments within their particular facilities, with a growing emphasis upon optimizing product output, enhancing quality control, as well as guaranteeing safety. Cleanrooms are just no longer restricted to high-tech semiconductor production or university research labs. Cleanrooms are now utilized in a wide range of settings. But, precisely, what exactly is a cleanroom?
A Formal Definition
A cleanroom was formerly characterized as an enclosed space within a production or otherwise research facility which was particularly built to regulate air pollution levels and also pressurisation, Temperature, humidity, as well as personnel access must all be met in order to satisfy the necessary environmental conditions needed. Cleanroom Certification is a good benchmark.
Cleanrooms have traditionally been used to safeguard goods or otherwise processes from the contamination in a number of businesses and research institutions, including the pharmaceuticals, biotechnology, life sciences, microelectronics, as well as food packaging. Contaminants comprised dust, gases, and microorganisms, and also particles produced by humans such as skin flakes, hair, and garment fibres, and perhaps other materials such as paper, pencils, paint, and otherwise coatings. Fume Hood Certification can be done easily.
To maintain product quality, worker safety, or perhaps the authenticity of research, all pollutants have to be managed. To ensure that the cleanrooms were appropriately constructed, a set of criteria was created to categorize the ability of a certain cleanroom design to limit pollutants. True "cleanrooms" must adhere to particle-count and particle-size standards in a given volume of air.
Of course, cleanrooms benefited businesses by assisting them in minimizing quality issues and increasing the product yield...something that manufacturing, laboratory, as well as other facility managers sought. These users generally desire to have control over their surroundings but don't need to adhere to particular Cleanroom Classification Standards. Clean Room Certifications are indeed very good.
Classification of Cleanrooms
Cleanrooms could be designed as well as operated to satisfy multiple cleanliness classes, depending upon the environmental conditions necessary for their usage, for organizations which must comply to certain cleanroom standards.
Measurement of Particle Size
Air particles in specifically a cleanroom are actually measured in microns or otherwise micrometers. Even the most intense microscopes could detect micron-sized particles, which are tiny than a live cell.
To put this into perspective, a strand of the human hair could range in width between 20 to 180 microns, with the average size being 50-70 microns. One tiny dust particle observed in a sun beam is roughly 60 microns in size. The human eye can't perceive things smaller than 50 microns specifically in size on a continuous basis. Pollen has a diameter of 30-50 microns. A normal indoor air sample may include up to 1 million particles per each cubic foot of air.
Keeping the Environment Clean
The air inside a cleanroom is always cleaned using Higher Efficiency Particulate Air filters to meet the appropriate environmental conditions. The filters push air past them, removing particles as tiny as 0.5 microns. The filtering system is determined by the amount of cleanliness needed.
