What Is an Air Shower?
Air showers are box-shaped devices installed at the entrances to clean rooms, etc. They use dust-free air that has passed through a highly purified, multi-layered filter called HEPA to remove dust from people's clothes.
Uses of Air Showers
Air showers are mainly used in semiconductor and precision equipment manufacturing facilities. In most cases, they are installed at the entrance to prevent dust from entering the clean room.
To maintain the cleanliness of the clean room, it is important to remove all dust in the air shower. Because it can remove dust from clothes in a few tens of seconds, it is sometimes installed at the entrance of apartments for pollen-allergic patients.
Principle of Air Showers
Air showers have double doors with interlocks that prevent both doors from opening at the same time. When a person enters the air shower from the outside, the air is injected through the jets for a set number of seconds. The air is highly purified through a HEPA filter.
This forces the air mixed with dust to circulate and purifies the air shower space. Even when no one is in the room, the air is gently circulated to ensure that the air shower space is always kept at a high level of cleanliness.
The interlocks on the double doors allow only a small amount of dust to enter when exiting, which also contributes to extending the life of the HEPA filter.
How to Select an Air Shower
Select an air shower that meets the cleanliness requirements of the clean room, as higher dust removal performance is more expensive. The cleanliness of a clean room is classified by ISO based on the size and quantity of particles inside.
Each air shower is selected by checking its guaranteed class. It is also possible to reduce costs by selecting a simple type of air shower that does not have a room. If the number of people coming in and out of the room is large or frequent, a large air shower that can accommodate several people at the same time may be selected.
Other Information on Air Showers
1. How to Use Air Showers
Air showers are equipment that removes dust to prevent dust from being brought into the clean room. However, if it is used improperly, it will not achieve the expected dust removal effect. First, decide on a standing position with a predetermined capacity, and mark the "stop" marker. Depending on the standing position, the air velocity hitting the body will decrease, and the dust removal effect will also be reduced.
Next, adjust the air outlet slightly downward toward the standing position. This has the effect of reducing the air blowing up and reducing re-contamination caused by the dust flying up. During the air shower, rotate 2-3 times with your arms outstretched so that the air blows over your entire body. After rotation, the unit waits in place until the set time.
Generally, set the air shower time to about 30 seconds for the one-sided blowout type and about 20 seconds for the two-sided blowout type.
2. Effects of Air Showers
Experiments have shown a correlation between the dust removal effect of air showers and the time setting. In the experiment, the dust removal rate for each size was measured for 10, 20, and 30 seconds for the one-sided and two-sided types of air showers.
This experiment showed that the one-sided blowout type had a low removal rate of fine dust particles and was inferior in dust removal effectiveness. With the two-sided blowout type, the removal rate of each size of dust was almost equal, and the dust removal effect was high.
These results indicate that it is appropriate to select a double-sided blowout type for clean rooms that require a high level of cleanliness. In places with high cleanliness requirements, it is more economical to use a single-sided blowing type to remove large dust and debris.
As for the dust removal time, experimental data for the two-sided blowout type shows that the dust removal effect is inferior at 10 s. Since there is no noticeable difference between 20 s and 30 s, it is generally recommended that the dust removal time be set at about 20 s. Since the dust removal effect of air showers varies depending on how they are used, it is necessary to ensure that they are used in an effective manner.
