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.

See technical integration options at HICLOVER Clean Air Solutions.
