304 Stainless Steel Manual Induction Air Shower

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 number of airborne particulate contaminants can be minimized. When personnel or goods pass through the air shower, contaminants are blown away by highly purified air that has been efficiently filtered. A high wind speed of 25m/s or more ensures effective blowing and removal of particles, which are essentially filtered out through primary and high-efficiency 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, along with items such as watches, mobile phones, and accessories.

2. Enter the inner changing room and wear purified 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 immediately. Infrared sensors will detect presence, and the air shower will automatically activate for a 15-second blow-off.

Factors affecting the air in the air shower:

1. Personnel working in the cleanroom must strictly adhere to cleanroom operating procedures. Doors and windows of the cleanroom should always remain closed. 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 in the cleanroom, but they are constrained by the final resistance of various filters in the purification system.

3. Equipment in the cleanroom requires regular, scheduled, and assigned personnel for cleaning and maintenance. The materials and cleaning liquids used must comply with cleanroom management regulations.

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

5. Rational分流 of人流 and logistics is crucial for maintaining cleanliness in the air shower room. Whether personnel change clothes and undergo air showering before entering the cleanroom, whether their attire meets cleanroom management standards, and whether personnel in特殊 production processes with high cleanliness requirements shower before entry—all these are important. Similarly, whether items are repackaged and air-showered before entering the cleanroom, and whether the repackaged materials meet cleanroom standards, are also critical.

Air showers are used in various cleanrooms and non-cleanrooms, as well as in graded cleanliness workshops, such as those in microelectronics, optoelectronics, semiconductors, pharmaceuticals, food, chemicals, aviation, automotive, printing, and laboratories. They are designed to remove dust particles larger than 0.3 microns from all parts of individuals when moving from low-cleanliness to high-cleanliness rooms, thereby preventing contamination upon entry into the cleanroom. They also serve as airflow buffers because, during door opening, air movement occurs. The air shower effectively contains airflow within itself, minimizing air pollution caused by air movement.

The air shower is a purification device for personnel entering cleanrooms and is highly versatile, compatible with all cleanrooms and clean workshops. 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 helps reduce contamination issues associated with personnel entering and exiting the cleanroom.
