304 Stainless Steel Air Shower Room with Automatic Sensing

The air shower is an essential passage for personnel entering the cleanroom. It helps reduce contamination issues caused by entering and exiting the cleanroom. By installing a fully functional "airlock chamber" at the entrance of the cleanroom, the amount of airborne particulate contamination can be minimized. When personnel or goods pass through the air shower, contaminants are blown away by highly purified air filtered through high-efficiency filters. A high wind speed of over 25 m/s ensures effective removal of particles, which are essentially filtered out by primary and high-efficiency two-stage filters. To maintain the safe use of the air shower and preserve the cleanliness of the cleanroom environment.

1. Before entering the cleanroom, outer clothing should be removed in the outer changing room, and items such as watches, mobile phones, and accessories should be taken off.

2. Enter the inner changing room and put on cleanroom garments, caps, masks, and gloves.

3. After pulling open the stainless steel air shower door and entering the air shower, the outer door will automatically close. Infrared sensors will detect presence, and the air shower will automatically activate for a 15-second blow-off.

Factors affecting the air quality in the air shower:

1. Personnel working in the cleanroom must strictly adhere to cleanroom operating procedures. Cleanroom doors and windows should remain closed at all times. There should be a buffer zone for the transfer of personnel and items between clean and non-clean areas, equipped with air shower devices to prevent airflow convection. Unauthorized personnel should not enter the cleanroom.

2. The air change rate in the cleanroom and the supply air volume of the HVAC purification system are the main internal factors maintaining positive pressure and cleanliness, but they are constrained by the final resistance of various filters in the purification system.

3. Equipment in the cleanroom requires regular, scheduled cleaning and maintenance by designated personnel. The materials and cleaning liquids used must comply with cleanroom management standards.

4. For users, the cleanliness level of the cleanroom is their primary concern. The biggest sources of contamination in an operational cleanroom are people and items entering the room. Dust particles generated during production are another factor affecting indoor cleanliness.

5. Proper separation of human and material flows is crucial for maintaining cleanliness in the air shower room. Before entering the cleanroom, personnel should change clothes and undergo air showering, ensuring their attire meets cleanroom management standards. In some high-cleanliness production processes, personnel may even need to shower before entry. Similarly, items should be repackaged and air-showered before entering the cleanroom, and the repackaged materials must meet cleanroom standards.

Air showers are used in various cleanrooms and non-cleanrooms across industries such as microelectronics, optoelectronics, semiconductors, pharmaceuticals, food, chemicals, aviation, automotive, printing, and laboratories. They are essential for removing particles larger than 0.3 microns from personnel before entering high-cleanliness areas, preventing contamination. Additionally, they serve as an airflow buffer, as opening doors can cause air movement. The air shower effectively contains airflow within itself, minimizing the risk of air pollution caused by air movement.

The air shower is a purification device for personnel entering cleanrooms and is highly versatile, compatible with all types of cleanrooms and clean facilities. When staff enter the workshop, this device uses powerful, clean air sprayed from rotating nozzles in all directions to effectively and quickly remove dust, hair, debris, and other particles attached to clothing. It significantly reduces contamination issues associated with personnel entering and exiting cleanrooms.
