How to avoid pollution inside with a cleanroom system
A cleanroom refers to any environment that is controlled for manufacturing certain products. Inside a cleanroom, airborne particles concentration is controlled to certain specific limits. The process of controlling the airborne particles involves getting rid of all the sub-micron contamination of the airborne, which occur as a result of various processes. People can cause contaminants such skin flakes, clothing debris, cosmetics, hair and many others. In addition, equipment and things such walls, paints, materials used for construction, spills and air condition debris among others can cause contamination.
The main way to prevent and avoid contamination of a cleanroom is by taking control of the whole environment. Some of the factors of the environment that are supposed to be controlled include the directions and flow rate of the air, humidity, the room temperature, pressurization. The sources of the airborne particles must be controlled at the same time or eliminated if there is that possibility. The moment a clean room system is built, there is need for it to be cleaned and maintained all the time.
The other way of maintaining a cleanroom and preventing it from any pollution is by the use of High Efficiency Particulate Air Filter (HEPA). These filters are used to maintain control of contamination. They are capable of filtering particles which are very tiny in size (up to 0.3 microns) with a minimum particle collective efficiency of about 99.97 percent.
Cleanrooms are part of companies that manufacturing companies such as biopharmaceutical, pharmaceutical, cosmetics, electronics and medical devices.
