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.
팬은 FFU 상단에서 공기를 흡입하여 1차 필터와 초고효율 필터를 통과하고, 필터링된 깨끗한 공기는 전체 공기 배출구 표면에서 0.45m/+20%의 속도로 클린룸으로 균일하게 내보냅니다. 균일한 흐름 층을 형성하여 깨끗한 공기의 수직 단방향 흐름을 보장함으로써 작업 공간 내에서 필요한 청결도를 보장합니다.
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.
