Why do cleanrooms need air showers?
Why do cleanrooms need air showers?The air shower room is the staff or material in and out of the clean room of the special channel, the purpose is to reduce the staff and in and out of the dust particles carried by the material, at the same time the air shower room of the double door interlocking can play a role in the role of the sealed dust-free clean room. Generally, it is used as the interval channel between all clean areas and non-clean areas.The air outlet on both sides of the air shower room adopts high-efficiency filter to filter the airflow, through the rotating nozzles from different directions to spray in and out of the personnel and goods, to remove the dust on the surface of the people and materials, and the air carrying dust particles at this time will pass through the primary and high-efficiency filters and then recirculate again. The overall design of the air shower room combined with power fluid science, internal automatic voice prompts, and door locks using double door interlock, when the door is closed to force the blowing shower through. Clean room air shower room also has a role to play, which is to have the effect of an airlock buffer, which can make the clean room maintain a certain pressure difference. A wind shower room can prevent outside contaminated gas into the clean room of the purification workshop and has a certain cleaning effect. The equipment in the air shower room is generally a pre-filter, the main filter, air jets, and blowers, the existence of the pre-filter is mainly to remove the particles of larger dust particles, this filtering device can be used to wash or hoover to wash the dust; the main filter is mainly for the filtration of dust more than 0.3um, high filtration efficiency, but this filter material is more fragile, so in the event of a blockage, to be replaced promptly; the main filter is mainly to filter 0.3um above dust, high filtering efficiency, but this filter material is more fragile, so in the event of blockage The main filter is to filter the dust above 0.3um, but the filter material is more fragile, so when there is blockage, it should be replaced in time; the air jet is mainly to remove the dust particles attached to the human body, and the effect to be achieved is to peel off the particles; the air blower is mainly to circulate the air for cleanliness. Therefore, the air shower room is an important barrier to the clean room, which is to block the dust into the workshop clean room of the first line of defense. |
