Cleanrooms refer to special chambers or facilities free from bacteria, dust, airborne microbes, aerosol particles and chemical vapors. Cleanrooms are secluded areas which are free from any type of contamination and even air within is filtered to exclude dust particles. Cleanrooms are mostly used in biotechnology, medical, life sciences, nuclear, electronics, aircraft and other industries who make products sensitive to environmental contamination.Cleanrooms can be quite large, sometimes a whole manufacturing facility covering thousands of square meters may be turned into a cleanroom. A variety of cleanroom product supplies are needed to keep cleanrooms in order. Some frequently used items used in operating cleanrooms include wastewater treatment system, ultrasonic cleanroom equipment, humidity control system, cleanroom particle counter, cleanroom panel filter, cleanroom desiccator, cleanroom air handling system, humidity testing devices, pressure gauge, etc.In the medical industry, cleanrooms are a commonplace. A number of measures are taken to keep the contaminants inside the facility within specified limits including cleanroom supplies, cleanroom equipment supplies, cleanroom product supplies and cleanroom services. For instance, the air supplied to a cleanroom from outside is filtered to hold back dust and other contaminants. Also, the air inside is recirculated through high efficiency particulate air (HEPA) and ultra low penetration air (ULPA) filters, both of these cleanroom product supplies and cleanroom equipment supplies remove internally generated pollutants. These measures are often absolutely necessary for cleanrooms. Also the air pressure within cleanroom is monitored using devices such as the pressure gauge.Further, the staff working within a cleanroom or the professionals rendering cleanroom services, enter and leave the enclosure through airlocks and air shower stages. In addition, the cleanroom equipment supplies and cleanroom supplies viz. mops and buckets, furniture, stationary, garments are specially designed to produce minimal air contamination. Cleanrooms also require periodic maintainable provided by companies providing cleanroom services, who use specialized cleanroom product supplies.
