Clean Rooms are workplaces where contamination is controlled.
The Clean Rooms are said to provide a conducive environment (for research,
development and manufacturing of equipment or processes) with a low level of
environmental pollutants such as dust, airborne microbes, aerosol particles, and
chemical vapors.
With the growing emphasis on quality checks & controls, zero tolerance on defects and
stringent manufacturing practices, the demand of clean rooms has increased manifold.
The Clean rooms are now being designed as specially constructed enclosed areas,
environmentally controlled with respect to airborne particles, temperature, humidity, air
pressure flow patterns, air motion, vibration, noise and viable organisms.
Major application areas of clean rooms are in the pharmaceuticals, hospitals, food
laboratory and many others requiring more stringent manufacturing conditions.
Contaminants can come from a wide variety of sources: air (the cleanliness of which is
defined according to the classes of clean rooms and classes of dust), water, chemicals,
the physical plant itself, and personnel.
