The air shower room is the necessary passageway for goods to enter and leave the clean room and plays the role of air lock room as a closed clean room together. In order to reduce the amount of dust particles brought about by goods in and out, the clean air flow filtered by high-efficiency filters sprays from rotary nozzles in all directions to the goods. It is useful and agile to remove dust particles. After the removal of dust particles, the filtered dust particles are recycled from the original and high-efficiency filters to the air-shower area.

In order to achieve the function of air shower, the air velocity of the nozzle outlet can reach more than 25 m/s, and the lowest is 18 m/s. The air shower machine provides modular assembling method, which can be assembled into various lengths of air shower scale according to actual needs.

Several factors affecting air quality in air shower room:

1. Operators in dustproof rooms should strictly follow the operating rules of dustproof rooms. The doors and windows of the dustless room should be closed at any time. The transfer of personnel and goods between the dustless room and the non-dustless room should have a buffer zone, and there should be a wind bath equipment to block the convection of air flow. Persons unrelated to production should not enter the dustless room.

2. The number of ventilation in the clean room and the air supply volume of the air conditioning and purification system are the primary internal factors to maintain the positive pressure and cleanliness of the clean room, but they are limited by the final resistance of filters at all levels in the clean room.

3. The equipment in the dustless room should be cleaned regularly, regularly and regularly. Whether the materials and liquids used in cleaning are in conformity with the requirements of cleanroom management, etc.

4. For users, the cleanliness of clean room is the focus of their most concern. The greatest source of pollution in running clean room is people and articles entering clean room. Dust particles occurring during production are another reason affecting indoor cleanliness.

5. Reasonable diversion of flow of people and logistics is of great significance to the cleanliness of indoor protection. Whether people change their clothes and blow before entering the clean room, whether their clothes conform to the cleanliness standards, whether some people who have high requirements for cleanliness in production process need to take a bath before entering the clean room, whether the goods are replaced by packing and blow before entering the clean room, whether the replaced materials conform to the cleanliness standards, etc.
