What is the specific function of the air shower room in the dust-free workshop
What are the specific effects of the air shower room in the dust-free workshop?
Many people may not fully understand why it is necessary to build an air shower room when they first come into contact with a cleanroom?
It is reported that many cleanrooms now have supporting air shower rooms, especially cleanrooms above 10000 level, which require such configurations. The reason why it is necessary to install an air shower room in a cleanroom with a capacity of over 10000 is that it can better assist the cleanroom in maintaining the cleanliness of the space, reduce the frequency of clean dust removal in the workshop, and bring better workshop safety and cost expenses.
Construction of cleanroom air shower room
An air shower room is a type of space that uses clean air to blow away various dust and bacteria on the surface of objects or goods, thereby removing them as much as possible and expelling them from the outside. In other words, it is similar to the "disinfection" before entering a purification workshop. After being cleaned in the air shower room, people will naturally bring less dust into the cleanroom, thus better maintaining the dust-free state in the workshop.
The use of air shower rooms also has a buffering effect. For example, if someone suddenly enters without knowing or understanding the requirements of the purification workshop, it may cause a lot of dust to enter the workshop, which may directly lead to changes in the production situation at that time and may cause huge property losses.
And if there is an air shower room, because the air shower room is built between the clean room and the non clean environment as a buffer zone, even if an uninformed person suddenly enters, he will only enter the air shower room and will not affect the workshop situation. After passing through the air shower room, the dust on his body will be removed, and then entering the workshop will not have too much impact, naturally providing more safety guarantee.

(Factors affecting the air quality of the air shower room) 1. The equipment in the cleanroom requires regular cleaning and protection by designated personnel, and whether the materials and cleaning liquids used in the cleaning process comply with the regulations of cleanroom management.
2. The operators in the cleanroom must strictly follow the operating rules of the cleanroom. The doors and windows of the cleanroom should be in a closed state at all times. There should be a buffer zone for the transfer of personnel and items between the cleanroom and non cleanroom, and there should be air bath equipment to prevent airflow convection. Personnel unrelated to production are not allowed to enter the cleanroom.
The reasonable diversion of people and logistics has important implications for protecting the cleanliness of the air shower room. Before entering the dust-free workshop, do people change clothes and shower, and do their attire comply with the standards of cleanliness management? Some personnel with high cleanliness requirements in production processes also need to take a bath before entering; Whether the packaging is replaced and blown before entering the cleanroom, and whether the replaced materials meet the cleanroom standards, etc. 4. The ventilation rate of the cleanroom and the air supply volume of the air conditioning purification system are the primary internal factors in maintaining the positive pressure and cleanliness of the cleanroom, but they are limited by the final resistance of the filters at all levels in the purification system.
For users, the cleanliness of the cleanroom is a key concern. The main sources of pollution in the operating cleanroom are people and items entering the cleanroom. Dust particles generated during production are also another factor affecting indoor cleanliness.
