The importance of air shower systems in cleanrooms

Air quality in Cleanrooms is critical to controlling particulate contamination, and Air Shower Systems play a pivotal role in this process. In high cleanliness environments, any minute contaminant can affect the production process and even the quality of the final product.

Principle of air shower room

Air Shower Room is a kind of local purification equipment, the main role is to reduce the personnel or goods in and out of the Clean Room brought about by the pollution problem. It’s working principle is to blow away dust through high-speed airflow to ensure the air quality of the Clean Room. Specifically, the air in the air shower room is filtered through the primary filter, and then pressed into the static pressure box by the high-pressure fan, the clean airflow filtered by the high-efficiency filter is sprayed out by the rotatable nozzle, blowing off the dust on the overalls, and the dusty air is sucked in by the fan through the coarse filter, and then recirculated again by the high-efficiency filter after pressurized flow.

When selecting an air shower room, the following key factors need to be considered

1. Size and Shape: According to the size and layout of the clean area for selection, consider the number of passers-by, pass goods, equipment size, personnel movement and other factors.

2. Airflow Speed: Directly affect the effect of removing pollutants, usually the airflow speed should be between 20-25m/s.

3. Inlet and Outlet Design: Affect the personnel in and out of the clean area space optimization, airflow flow and other factors, the common straight to the I-type, L-type, T-type import and export air shower room and so on.

4. Control System: Should have stability and ease of operation, common control methods are button control, touch screen control.

5. High-efficiency Filter Selection: Choose the right high-efficiency filter can effectively purify the air, need to consider the filtration efficiency, service life and other factors.

Key points for air shower room maintenance

1. The inner and outer control panels do not hit with hard blocks to prevent scratches.

2. The door is an electronic device interlock, when a door opens another door is automatically locked, do not additionally force the power switch.

3. Regularly use the instrument to determine the technical indicators of the equipment, such as does not meet the requirements of the technical parameters should be dealt with in a timely manner.

4. According to the actual use of the situation, regularly remove the filter media in the primary air filter cleaning.

5. When the wind speed is found to become small, it may be that the high efficiency filter accumulates too much dust and should be replaced in time.
