A special industrial production environment known as Clean Room strongly affects product quality, operational efficiency and employee health through the internal air cleanliness. The Air cleanliness level serves as a crucial parameter to evaluate Cleanroom air quality, because it determines if the Cleanroom satisfies particular manufacturing requirements. The knowledge of Cleanroom air cleanliness level remains vital for both effective operation and product quality purposes in Cleanroom environments.

In the field of Cleanroom environmental control, AHU (Air Handing Unit) and HVAC system are two concepts that are often mentioned but easily confused. 

In modern industrial production, especially in the pharmaceutical, food, and semiconductor industries, Clean Room standards are of paramount importance. ISO and GMP are two oft-repeated concepts, each with different requirements for Clean Rooms.

In high-tech manufacturing, biomedicine, scientific research and other fields, Clean Room is to ensure product quality and experimental accuracy of the key environment. And the Clean Bench, as one of the core equipments in the Clean Room, has become an indispensable “guardian” in these fields with its unique working principle and significant role.
