As we all know, when the air shower room works, it mainly removes the dust from the human body through the air blow. However, for the people who work in the clean room, they must go through the air shower room to get into the clean area every day, so it is harmless to the body. ?

First, let's first understand the internal structure of the air shower:

The main components of the air shower interior include: large air volume centrifugal fan, high efficiency filter, automatic control system, intelligent voice system, infrared sensing system, etc. Firstly, the relevant control system is excluded, and it is more likely that the wind blown by the fan of the air shower room .

When the air shower is working, the wind is first sucked in the air shower by the fan. After the dust is filtered through the initial effect and the high efficiency filter, the wind speed of 20-25M/S is blown onto the human body, and the wind blows out. The initial effect and high-efficiency filtration, that is, the actual blown out wind is clean, we can understand that it is dozens of times higher than the ordinary indoor air-conditioning air cleanliness, and the clean wind is harmless to the human body. This should be understandable to everyone.

Air shower chamber

If it is necessary to say that it has an impact on the human body, it may be because the wind speed blows on the person will not cause a cold, and this related science has also proved that the general showering time of the wind shower room is generally about 10-20 seconds. At this point of time, there is no such thing as the human body. Besides, when people go into the air shower room, they wear dust-free clothes, that is, the clothes they wear are relatively thick.

Therefore, the air shower chamber is actually a normal physical process, without radiation, and has no harm to the human body.

The aspects that must be paid attention to when purchasing the [air shower room]

The air shower is the only way for employees to enter the clean room and the non-clean room. Through the air shower room, it can better remove the large amount of dust particles brought by people or goods into and out of the clean room, thus ensuring the cleanliness of the clean room.

Then, how to choose the air shower room has become a difficult choice for enterprises; choosing a good quality air shower room, like choosing to buy a house, requires careful calculation, mainly focusing on the following aspects:

1. Choose the air shower room suitable for the enterprise. The air shower room is divided into a single air shower room, a double air shower room, a multi-person air shower room and a wind shower channel, etc. The maintenance department does not know which type of air shower room to choose; usually the air shower room is shipped from the factory. Generally set to 15S blowing once, such as clean workshop for about 20 people, to control the completion within 10 minutes, then you can choose single air shower room or double air shower: 15S people \ times * 3 people = 45S, also That is to say, in a minute, a single air shower can pass 3 people, and in 7 minutes, it can pass 20 people completely; if the time is to be controlled within 20 minutes, if you pass 20 people, you should choose a double air shower or a multi-person air shower. .

2. The direction of blowing in the air shower. According to the blowing method, the air shower can be divided into: single blow shower room, double blow shower room, and three blow shower rooms. In fact, the nozzle and direction of the air shower are not increased, and the blowing effect will be better. These are mainly determined by the close relationship between the fan parameters used by the air shower manufacturer (the surface wind speed is generally greater than 20 m\ sec); If the double shower room is equipped with only one fan, then the double blow will definitely be higher than the wind speed of the three blow chambers, so the blowing effect is better than the three blows; if the double fan is used, the overall blow effect of the employee is better. You can choose three blows.

3, the material selection of the air shower room is also the main factor determining the price of the air shower. The materials of the air shower room are mainly composed of cold-rolled steel plate multi-layer pickling electrostatic spraying, stainless steel inside the outer cold plate, and all stainless steel. Stainless steel material is resistant to strong acid and alkalinity. Cold-rolled steel plate multi-layer pickling electrostatic spraying is more durable if it is not sloppy and the site is not strong acid or alkali; if the site is relatively humid or has acid and alkali gas, then To choose a full stainless steel air shower, or vice versa, you can also choose a full shower cold steel material air shower.
