The air shower room is a necessary passage for people to enter the clean room, which can reduce the pollution caused by entering and leaving the clean room, and reduce the large amount of dust particles caused by the entry and exit of people and goods. The installation of a fully functional "airlock" at the entrance of the clean room can reduce the amount of air pollution particles. When people and goods pass through the air shower room, the pollution particles are sprayed out by highly clean air that has been efficiently filtered. The high wind speed of 25m/s or more ensures that the effective spraying and drifting particles are basically filtered out by the primary and high-efficiency two-stage filters. To ensure the safe use of the air shower and maintain the cleanliness of the cleanroom environment
1. When entering a clean and dust-free room, one should take off their outer clothing and remove items such as watches, mobile phones, and accessories in the external changing room.
2. Enter the dressing room and wear clean and dust-free clothing, hats, masks, and gloves.
3. After opening the stainless steel air shower door and entering the air shower room, the air shower door will immediately close the outer door automatically. With infrared sensing, the air shower will start automatically and blow for 15 seconds.
3 factors affecting the air in the air shower room:
1. The operators in the clean room must strictly follow the operating rules of the clean room. The doors and windows of the clean room should be in a closed state at all times. There should be buffer zones for the transfer of personnel and items between the clean room and non clean rooms, and there should be air bath equipment to prevent airflow convection. Personnel unrelated to production are not allowed to enter the clean room.
2. The ventilation rate of the clean room and the air supply volume of the air conditioning purification system are the main internal factors that maintain the positive pressure and cleanliness of the clean room, but they are constrained by the final resistance of the filters at all levels in the purification system.
3. The equipment in the cleanroom requires regular, scheduled, and manned cleaning and maintenance, and whether the materials and cleaning liquids used in the cleaning process comply with the regulations of cleanroom management.
4. For users, the cleanliness of the cleanroom is their top concern. The biggest sources of pollution in operating cleanrooms are people and items entering the cleanroom. Dust particles generated during production are also another factor affecting indoor cleanliness.
5. The reasonable diversion of people and logistics is of great significance for maintaining the cleanliness of the air shower room. Do people change clothes and shower before entering the clean room, and do their attire meet the standards of cleanliness management regulations? Some personnel with special production processes and high cleanliness requirements also need to take a bath before entering; Whether the packaging of the goods is replaced and blown before entering the clean room, and whether the replaced materials meet the standards of the clean room, etc.
