Affect the air quality of air shower

The air shower is the necessary passage for the goods to enter and exit the clean room and at the same time function as a closed chamber of the air lock chamber. In order to reduce the large amount of dust particles caused by the ingress and egress of the goods, the clean air stream filtered by the high-efficiency filter is sprayed from the various directions to the cargo by the rotatable nozzle, and the dust particles are effectively and quickly removed, and the dust particles after the removal are further The high efficiency filter is filtered and recirculated to the air shower area.

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

Several factors affecting the air quality of the air shower:

1. The operators in the clean room should work in strict accordance with the operating rules of the clean room. The doors and windows of the clean room should be closed at any time.

Enter the clean room.

2. The number of air exchanges in the clean room and the air supply volume of the air conditioning purification system are the main internal factors for maintaining the positive pressure and cleanliness of the clean room, but it is limited by the ultimate resistance of the filters in the purification system.

3. The equipment in the clean room requires regular, regular and fixed cleaning and maintenance. Whether the materials and cleaning liquid used in the cleaning meet the requirements of clean room management.

4. For the user, the cleanliness of the clean room is the focus of their concern. The clean room in the clean room is the person and the items that enter the clean room. The dust generated in the production also affects the indoor cleanliness. Another reason for the degree.

5. Reasonable diversion of people flow and logistics has important significance for maintaining cleanliness in the room. Whether people dress and blow before entering the clean room, whether the dress meets the standards of clean management regulations, some people with special production requirements for cleanliness need to take bath before entering; whether the items are replaced before entering the clean room The package is blown, and the replaced materials meet the clean room standards and so on.
