What is a clean room？

Definition of Clean Room: Also known as Clean Work Room or Purification Room, it is a small and simple clean room that can be quickly established.
Cleanroom level: It is usually divided into Class 100 cleanrooms, Class 1000 cleanrooms, and Class 10000 cleanrooms.

Materials for the clean room: stainless steel square bracket, iron square bracket, aluminum profile bracket. Anti static curtains and organic glass baffles can be used around the clean room.
Working principle of clean room: The FFU fan filtration unit undergoes the first filtration through the primary filter, and then the second filtration through the high-efficiency filter. The entire air outlet surface is uniformly sent out into the clean room, making the clean air flow vertical and unidirectional, ensuring the required cleanliness in the work area.
The advantages of a clean shed are that it is easy to install, has a short construction period, and allows for a vertical unidirectional flow of clean air in areas that require high cleanliness. This ensures that the required cleanliness level for the working area inside the shed is increased to reduce costs.
Factors affecting airflow in clean rooms: There are many factors that affect airflow in clean rooms, such as process equipment, personnel, clean room assembly materials, lighting fixtures, etc. At the same time, the diversion point of airflow above production equipment should be considered as a factor.
The air flow diversion point on the surface of general operation platforms or production equipment should be located at 2/3 of the distance between the clean room space and the partition board, so that the air flow can flow from the inside of the process area to the work area while the operators are working, and carry away the fine dust; If the diversion point is configured in front of the process area, it will become an improper airflow diversion. At this time, most of the airflow will flow to the process area, and the dust caused by the operator’s operation will be carried to the back of the equipment. As a result, the workbench will be contaminated and the yield will inevitably decrease.
Obstacles such as workbenches in clean rooms will experience eddy currents at their junctions, resulting in poor cleanliness in their vicinity. Drilling air return holes on workbenches will minimize the occurrence of eddy currents; The selection of appropriate assembly materials and the completeness of equipment layout are also important factors in determining whether airflow becomes a vortex phenomenon.
FFUの上部からファンで空気を吸い込み、一次フィルターと高効率フィルターで濾過し、濾過された清浄空気を吹出口全面に0.45m/s±20%の速度で均一にクリーンルームに送り出します。均一な流動層を形成することで、清浄空気の垂直一方向の流れが確保され、ワークスペース内の必要な清浄度が保証されます。
A clean room is a simple clean room that can be quickly assembled. It has the characteristics of fast installation, short construction period, low price, and easy mobility. Controlling the main production processes in a smaller environment is also the best choice for clean room design.
