摘要:Air shower room is the passageway for goods to and from the clean room and plays the role of airlock room sealing clean room. In order to reduce a large number of dust particles due to the goods in and out, the clean air filtered by the high efficiency filter is sprayed from all directions by the rotating nozzle on the goods, effectively and quickly remove dust particles, dust particles cleared by the primary and high efficiency filter after recycling to the air shower area.
Air shower room is the passageway for goods to and from the clean room and plays the role of airlock room sealing clean room. In order to reduce a large number of dust particles due to the goods in and out, the clean air filtered by the high efficiency filter is sprayed from all directions by the rotating nozzle on the goods, effectively and quickly remove dust particles, dust particles cleared by the primary and high efficiency filter after recycling 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 more than 25m/s, and the wind speed of blowing to the surface of the goods is 18m/s. Air Shower provides modular assembly, according to the actual need to assemble into various length of the size of the air shower.







Several factors affecting the air quality of the air shower chamber:

Personnel unrelated to production should not enter the clean room.







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







3. The equipment in the dust-free room requires regular, regular and fixed cleaning and maintenance, and whether the materials and cleaning liquids used in the cleaning meet the regulations of clean room management, etc.
