How do Cleanrooms work?

A Cleanroom essentially provides an isolated, controlled environment for the purpose of keeping the external environment safe from harmful substances or handling contamination-sensitive substances. Tight controls limit larger airborne particle contamination and the density of sub-microns inside the Cleanroom.

Controlling contamination requires control of the total environment. To remove particles from the Cleanroom, elements such as specialised filtration, humidity, temperature, pressurisation, as well as air flow direction and rate must all be tightly kept in check.
