CORNER AIR SHOWER: PRINCIPLE AND APPLICATIONS

Understanding the Technology Behind Cleanroom Entry Solutions

I. Introduction

The Corner Air Shower is a specialized cleanroom entry system designed to remove particulate contamination from personnel and materials before they enter controlled environments. Unlike standard straight-through air showers, the corner design allows flexible installation in limited spaces and optimizes workflow in cleanroom layouts.

II. Working Principle

The Corner Air Shower operates using high-velocity, HEPA-filtered air jets. When personnel or trolleys enter the chamber, the automatic door system seals the enclosure, and strategically positioned nozzles emit streams of air at speeds up to 25 m/s. These air jets dislodge dust, lint, hair, and other contaminants, which are then captured by a recirculating filtration system. The corner configuration ensures that air circulation is optimized even in tight spatial arrangements.

III. Key Components

• HEPA Filtration System: Ensures removal of ≥99.97% of particles ≥0.3 μm.
• Automatic Interlocking Doors: Prevent cross-contamination between clean and non-clean zones.
• High-Velocity Nozzles: Adjustable for targeted decontamination.
• Corner Layout Frame: Designed for space efficiency without compromising performance.

IV. Applications

Corner Air Showers are widely used in industries requiring strict contamination control, such as:

• Cleanroom Engineering
• Medical and Pharmaceutical Facilities
• Biotechnology Laboratories
• Food Processing Plants
• Electronics and Semiconductor Manufacturing
• Environmental Science and Technology Projects

V. Advantages of Corner Design

• Space-Saving Layout: Ideal for cleanrooms with limited floor space.
• Workflow Optimization: Allows smoother personnel and material movement.
• Enhanced Airflow Coverage: Air jets reach more angles due to the corner positioning.
• Customizable Configuration: Door and nozzle positions can be adapted to project needs.

VI. Operation and Maintenance

Regular maintenance is crucial for ensuring performance. This includes periodic HEPA filter replacement, nozzle cleaning, and mechanical inspections. An integrated monitoring system can alert operators to any performance deviations.

VII. Compliance and Standards

Corner Air Showers are manufactured in accordance with international cleanroom standards such as ISO 14644 and GMP requirements. Materials used are often powder-coated steel or stainless steel, ensuring durability and corrosion resistance.

VIII. Target Users

Engineering companies specializing in cleanroom projects, medical facilities, laboratory construction, and environmental technology are the primary users of Corner Air Showers. The system helps these industries maintain strict hygiene and safety standards.

IX. Future Trends

Emerging developments include integration with smart building management systems, touchless operation panels, and energy-efficient airflow control to reduce operational costs.

X. Conclusion

The Corner Air Shower is a vital component in maintaining cleanroom integrity, offering both contamination control and spatial efficiency. As industries continue to demand higher cleanliness standards, this technology will play an increasingly important role in modern facility design
