※ What is cleanroom？
Cleanroom - Room in which the concentration of airborne particles and contamination is controlled, and which is constructed and used in a manner to minimize the introduction, generation and retention of particles inside the room.

The flow design will be some different for the cleanroom classification, and flow will be turbulence flow and laminar flow.。
Laminar Flow Definition: Laminar flow is where a fluid flows in one direction, with no interruptions from turbulence.
In the case of a vertical laminar flow type and horizontal laminar flow type, clean air has a unidirectional down flow from the face of the fan filter unit and flow back to both side of wall or raised floor, which is suitable for high classification cleanroom.
