In high-tech production fields such as electronics manufacturing, biopharmaceuticals, and food processing, cleanliness directly determines product yield and production safety. As the "first line of defense" in clean zones, the air shower has evolved from a simple "dust blowing" device into critical equipment integrating air purification, airlock contamination prevention, and data collection.

However, production environments, cleanliness levels, and personnel/material flow patterns vary greatly across different industries. Adopting a "standard" air shower can often lead to installation location conflicts, substandard purification efficiency, or even become a bottleneck in the production process. This article will analyze how to precisely address challenges in various complex environments through customized air shower solutions, focusing on three dimensions: scenario adaptation, core parameter customization, and intelligent integration.

I. The Core of Customization: Not Just Dimensions, But Logic

Customization is not simply "scaling up or down," but a secondary in-depth design based on actual working conditions. A high-quality customized solution needs to cover the following three levels:

1. Structural Form Customization: Solving Spatial Layout Challenges
In many renovation projects, irregular spaces are the biggest enemy.

• Corner Air Shower: For situations where the clean area has a 90-degree corner, columns, or narrow passages, a corner air shower can be embedded directly into the corner, utilizing a转向 structure to achieve "L-shaped" passage. This not only prevents straight-through air showers from occupying main thoroughfares but also transforms idle corners into purification hubs, potentially increasing space utilization by over 30%.

• Tunnel Type: For production lines with extremely high personnel or material flow, standard box-type air showers cannot meet traffic efficiency requirements. In this case, a tunnel air shower can be customized, extending the blow-down area and using multiple nozzle arrays to allow multiple people to undergo continuous blow-down simultaneously, ensuring purification效果 while eliminating congestion.

2. Material and Process Customization: Addressing Harsh Environments
Different production environments have vastly different requirements for equipment corrosion resistance and cleanliness:

• Pharmaceutical and Food Industries: Must use 304 or 316L stainless steel, requiring seamless welding to prevent bacterial growth and withstand frequent chemical disinfection.

• Electronics and Chip Industries: Anti-static treatment is a key consideration. Components including the cabinet panels, sealing strips, and even nozzles must have a surface resistance controlled between 10⁶-10⁹ Ω to prevent electrostatic discharge from damaging High-precision components.

3. Functional Module Customization: Loading as Needed

• Sterilization and Purification Modules: Ozone generators can be configured for food workshops; UV germicidal lamps are needed for medical sterile environments.

• Static Elimination Modules: In electronics factories or plastic processing workshops, high-speed airflow friction can easily generate static electricity, attracting dust. Customized ion static elimination devices can effectively neutralize charges, improving cleaning efficiency.

II. How to Customize Technical Parameters?

Customization must be based on scientific calculations. Depending on the cleanliness level and usage it, the logic for setting key parameters also differs:

1. Air Velocity and Filtration Efficiency: Non-Negotiable Hard Indicators
The core of an air shower lies in "blowing" and "filtering."

• Air Velocity Requirement: The nozzle outlet velocity needs to be stable at 25-30m/s, and the velocity reaching the person's surface should not be low 18m/s to effectively dislodge attached particles.

• Filtration Grade: For Class 100/ISO 5 or Class 1000/ISO 6 clean areas, HEPA filters must reach H13 grade or above, with a filtration efficiency requirement of ≥99.97% for 0.3μm particles. For Common Class 100,000/ISO 8 workshops, H11 grade filters are sufficient.

2. Dimension Customization: Based on Ergonomics

• Personnel Passage: The width of a single-person air shower is recommended to be 800-1000mm, with a depth of ≥1200mm to ensure personnel can turn around naturally and receive 360-degree blow-down; the width for a double-person air shower should be extended to 1500-1800mm.

• Material Passage: If forklifts or large carts need to pass through, the width should be ≥1500mm, depth ≥2000mm, and consideration must be given to using high-strength, wear-resistant, anti-slip flooring at the bottom to prevent wheels from slipping and damaging the cabinet.

3. Intelligent Control Systems: From Automation to Digitalization
Modern customized air showers are integrated into the industrial internet architecture:

• Data Interaction: Customize the PLC control system to upload blow-down records (personnel ID, time, air velocity, duration) in real-time to the central monitoring system, meeting GMP data traceability requirements.

• Differential Pressure Monitoring: Integrate a differential pressure sensor. When the HEPA filter becomes clogged, causing a drop in air velocity, it will automatically issue an early warning alert, reminding staff to perform maintenance and replacement, avoiding the risk of sterility failure due to equipment degradation.

III. Industry-Specific Customized Solution References

To demonstrate the necessity of customization more intuitively, here is a comparison of typical customization strategies across different industries:

Electronics/Semiconductor Industry

• Core Pain Points: Micro-dust causing circuit shorts, ESD damaging components

• Customization Strategy: Full stainless steel anti-static treatment + ionizer fans

• Parameter Focus: High air velocity (25m/s+), H13 HEPA filters, data logging function

Biopharmaceutical Industry

• Core Pain Points: Microbial contamination, cross-contamination

• Customization Strategy: 304 seamless welded stainless steel + UV sterilization/ozone

• Parameter Focus: Rounded corner design for easy cleaning, air velocity and pressure differential interlock,all records complying with GMP standards

Food & Beverage Industry

• Core Pain Points: Pest control, personnel carrying hair/debris

• Customization Strategy: High-capacity tunnel type + anti-slip durable flooring

• Parameter Focus: Emphasis on flow efficiency, easily removable and washable pre-filters, waterproof control panel design

Precision Machining/Laboratories

• Core Pain Points: Irregular spaces, low-frequency use

• Customization Strategy: Corner air shower / small single-person single-blow unit

• Parameter Focus: Adapting to on-site installation dimensions, balancing space aesthetics and passage functionality

IV. Procurement Advice: How to Ensure Customization Success?

1. On-Site Survey is Prerequisite: High-quality customization doesn't just rely on blueprints. The manufacturer should send technical personnel to conduct an on-site survey of dimensions, confirm column locations, and identify power and air source interfaces, thereby mitigating installation risks.

2. Define Acceptance Criteria: Clearly specify in the contract that filtration efficiency must pass PAO leakage testing, and air velocity must be verified with an anemometer, avoiding acceptance based solely on "feel."

3. Focus on Post-Maintenance: Customized equipment should consider the convenience of back maintenance. For example, reserve a maintenance access hatch on the top for easy HEPA filter replacement; the control system should have fault self-diagnosis functions for quick troubleshooting.

Conclusion

Choosing a customized air shower essentially means choosing precise control over your production environment. It is not just about purchasing a piece of equipment, but rather a contamination control solution tailored based on your production processes, spatial layout, and compliance requirements.

By collaborating with manufacturers possessing in-depth customization capabilities and managing the entire process from dimensions and materials to intelligent systems, companies can not only ensure their clean areas meet ideal production standards but also reduce energy consumption and maintenance costs in the long run, truly achieving "one investment, long-term benefits."
