A clean room is a controlled environment that maintains low levels of pollutants such as dust, airborne microbes, aerosol particles, and chemical vapors. The clean room facility works on the principle of controlling the number of contaminants in the air through a combination of factors such as airflow, air filtration, humidity, and temperature control. Clean rooms are designed to prevent contamination in sensitive processes and products, particularly in industries like pharmaceuticals, biotechnology, semiconductor manufacturing, and aerospace.
The rooms atmosphere is continually purified using high-efficiency particulate air (HEPA) filters, which capture particles as small as 0.3 microns. The airflow within the room is carefully controlled to ensure that clean air enters through the ceiling and exits through the floor, creating a laminar flow that minimizes particle intrusion.
