Air Showers and Automatic Roll Air Filters: The First Line of Defense in Cleanroom Environments

The Role of Air Showers in Global Cleanroom Industries

Before entering a pharmaceutical production hall, semiconductor fab, or surgical operating room, workers often pass through a small chamber known as an air shower. This critical unit ensures that particles, bacteria, and dust do not enter sensitive clean zones.

Air showers act as a protective gate, much like security scanners in airports. When a person enters, high-velocity filtered air—typically exceeding 20 m/s—blows across clothing to remove attached dust or microorganisms. The particles are then captured by a filtration system, often incorporating prefilters such as the HICLOVER Automatic Roll Air Filter.

By combining air showers with automatic roll filters, facilities in industries such as electronics, food processing, and biotechnology achieve compliance with ISO 14644 cleanroom standards, while reducing energy consumption and maintenance costs.

Technical Aspects of Air Showers

1. Airflow Velocity
   Effective air showers operate at wind speeds above 20 m/s, strong enough to dislodge particles from garments, similar to wind that can move small branches or lift dust from the ground.

2. Blowing Angle
   Optimal decontamination occurs when nozzles deliver air at 30–60 degrees, allowing turbulence to shake free particles deeply embedded in fabric.

3. Automation and Control
   Modern air showers use infrared sensors and PLC-based automation to trigger air bursts, interlock doors, and prevent unclean air from entering controlled areas. Integration with roll filters ensures consistent airflow by automatically advancing fresh filter media when resistance builds.

Why Combine with Automatic Roll Air Filters?

While HEPA and ULPA filters handle fine particles, they are costly and sensitive to large dust loads. The HICLOVER Automatic Roll Air Filter acts as a prefilter system, reducing load on downstream units.

Benefits:

• Energy Efficiency: Stable airflow reduces fan overwork.

• Extended Filter Life: HEPA replacements can be delayed significantly.

• Global Application: Already adopted in facilities across the U.S., Canada, Germany, Vietnam, and the Middle East, where ESG and GMP standards drive cleaner production.

Applications Beyond Pharma and Healthcare

• Semiconductor Industry (Taiwan, Korea, U.S.): Protects wafers in ISO Class 5–6 environments.

• Food & Beverage Plants (Europe, North America): Prevents bacterial contamination in packaging areas.

• Hospitals and Clinics (Africa, Asia): Ensures sterile operating conditions.

• Mining & Industrial Sectors (Australia, Canada): Applied in dust-heavy environments where HVAC requires robust prefiltration.

在制药车间、半导体工厂或医院手术室前，人们常常需要进入一个“小房子”——这就是风淋室。风淋室通过强力的洁净气流将附着在衣物上的灰尘、细菌吹落，并通过过滤系统进行捕捉，从而确保进入洁净区的空气环境达到标准。

现代风淋室普遍结合了红外感应与PLC自动化控制，不仅能自动感应人员进出，还能与HICLOVER自动卷绕式空气过滤器配合使用，保持稳定气流，减少人工维护。

风淋室的风速通常需要达到 20m/s以上，吹风角度在 30–60度，这样才能有效去除附着在衣物纤维深处的颗粒。与HICLOVER卷绕式过滤器结合使用后，能够显著延长HEPA过滤器寿命，降低能耗和运行成本。

这种组合不仅在制药和医疗领域应用广泛，也逐渐推广到食品加工、电子制造、矿业通风等行业。全球包括美国、加拿大、欧洲和东南亚的工厂，都已经将风淋室+自动卷绕式过滤器视为符合 ISO 14644国际标准 的关键解决方案。
