For the Air shower, I believe that we are not strange, it is the necessary way people enter the workshop. It can reduce the pollution problem formed in and out of the workshop, reduce many dust particles in and out of the workshop, reduce the number of air pollution particles in the workshop. The air shower is a necessary passage for cargo entering and leaving the clean room and also plays the role of airlock chamber. In order to reduce the large amount of dust particles brought in and out of the cargo, the clean airflow filtered by the HEPA filter is sprayed on the cargo from the rotating nozzle in all directions to effectively and quickly remove the dust particles, and the cleared dust particles are then re-cycled to the air shower area after being filtered by the primary and high efficiency filter.

In order to achieve the effect of spraying, the wind speed of the nozzle outlet designed by the air shower can reach 25m/s or more, and the wind speed blowing to the surface of the goods is 18m/s. The air shower provides a modular assembly method, which can be assembled into various lengths of air shower size according to actual needs.

Several factors affecting air quality of shower:

1. Operators in the dust-free room shall work in strict accordance with the operating rules of the dust-free room. The door and window of the clean room should be in the closed state at any time, the transfer of personnel and items between the clean room and non-clean room should be a buffer zone, and there is a wind bath equipment to prevent the convection of airflow, personnel unrelated to the production can not enter the clean room.

2. The ventilation frequency of the dust free room and the air supply volume of the air conditioning purification system are the main internal causes to maintain the positive pressure and cleanliness of the dust free room, but it is restricted by the final resistance of filters at all levels in the purification system.

3. The equipment in the dust-free room shall be cleaned and maintained by regular, regular and appointed personnel. Whether the materials and cleaning liquid used in cleaning meet the requirements of clean room management, etc.

4. For users, the cleanliness of the clean room is the focus of their concern. The pollution source of the clean room in operation is people and articles entering the clean room, and the dust particles generated in production is another reason affecting the indoor cleanliness.

5. Reasonable flow of people and logistics is of great significance to maintain the cleanliness of the room. People in the clean room before whether to change clothes and shower, dress is in line with the standards of clean management standards, some production technology special requirements of high cleanliness of the personnel before entering even wash bath; Whether the material is changed before entering the clean room, whether the material after the change conforms to the clean room standard, etc.
