How to design a channel type air shower?

In cleanroom environments, maintaining air quality is critical to minimizing contamination. A channel type air shower serves as a vital entry point for personnel and materials, effectively eliminating dust and particulate matter. This article outlines the key considerations for designing an efficient channel type air shower to enhance operational cleanliness and comply with industry standards.

How to design a channel type air shower?

Designing a channel type air shower involves understanding airflow dynamics, material selection, and ensuring compliance with Cleanroom standards. Careful planning will yield an efficient system that enhances cleanliness while meeting operational needs.

1. Airflow Dynamics：Proper airflow design is crucial for effective contamination control. The air shower should create a high-velocity airstream to dislodge particles from surfaces.

2. Material Selection：Choosing suitable materials is vital for durability and ease of cleaning. Stainless steel is a popular choice due to its resistance to corrosion and chemical damage.

3. Size Specifications：The dimensions of the air shower must accommodate personnel and equipment, ensuring adequate space for the airflow to perform effectively.

4. Regulatory Compliance：Ensure adherence to relevant specifications and standards, such as ISO 14644-1, to maintain cleanroom integrity and operational efficiency.

List of relevant specifications and standards:

• iso 14644-1

• FS209E

• GMP Guidelines

Air shower shell material

The shell material of an air shower plays a crucial role in its functionality and longevity. It must be selected based on factors like durability, ease of maintenance, and resistance to contamination. Stainless steel is the preferred choice due to its non-porous surface, making it easy to clean and resistant to bacteria. Additionally, it can withstand harsh cleaning agents commonly used in cleanroom environments.

Choosing high-quality materials not only enhances the air shower’s performance but also contributes to the overall integrity of the cleanroom. Other materials, like acrylic, may be used for visibility but often lack the durability required for high-traffic areas.

In summary, selecting the right shell material is essential for ensuring the air shower meets industry standards and maintains a clean environment.

Air shower size specifications

Personnel Dimensions

The air shower should accommodate the average size of personnel, typically around 80 cm in width, ensuring sufficient space for movement without hindrance.

Depth and Height

Standard depth is generally 150 cm, while the height should be at least 210 cm to allow for comfortable use, especially for taller individuals or those wearing protective gear.

Entry and Exit Clearance

A minimum clearance of 30 cm should be maintained at the entry and exit points to facilitate smooth transitions.

Customizable Sizes

While standard sizes are effective, custom dimensions can be designed based on specific facility requirements, ensuring optimal functionality in various operational settings.

Air shower high-efficiency filtration system

1. Filtration Types

A high-efficiency filtration system is integral to an air shower's performance, utilizing HEPA or ULPA filters to capture airborne particles effectively.

2. Filtration Mechanism

HEPA filters can capture at least 99.97% of particles larger than 0.3 microns, ensuring superior air cleanliness. The filtration system should be accessible for regular maintenance and replacement to maintain efficiency. Regular checks and adherence to a maintenance schedule are essential to ensure optimal airflow and filtration performance.

ULPA filters, which provide even higher filtration efficiency, can also be considered for environments requiring ultra-clean conditions. The choice between HEPA and ULPA depends on the specific CleanRoom class and operational requirements.

3. System Maintenance

Regular maintenance of the filtration system is crucial for optimal performance and longevity, ensuring that the air shower operates effectively in maintaining cleanroom standards.

Air Shower Dedicated Fan Configuration

The fan configuration is critical to ensuring the required airflow and pressure in an air shower. The choice of fan impacts the air velocity, energy consumption, and noise levels.

Air Shower 360° Nozzle Design

The 360° nozzle design ensures uniform distribution of airflow around the personnel, providing comprehensive contamination removal.

1. Optimal Nozzle Placement

Nozzles are strategically placed to cover all parts of the personnel’s body, including their clothing, shoes, and hair. This ensures thorough cleaning from all angles.

2. Advanced Nozzle Technology

Nozzles with adjustable airflow are ideal for customized applications. High-velocity nozzles, strategically located at various angles, allow for complete coverage and efficient particle removal, reducing contamination risk.

3. Design Flexibility

The nozzle design can be adapted for different environments, providing flexibility for varying cleanroom applications. Effective nozzle design is a key element for high-performance air showers.

Determine the Specifications of the Air Shower According to the Number of Personne

The size and capacity of the air shower should be determined by the number of personnel using it simultaneously, ensuring effective decontamination without delays or bottlenecks.

Single-Use Air Showers

Designed for individual use, these compact units are suitable for small teams or low-traffic environments, with dimensions typically around 1.2m x 1.2m x 2.2m.

Multi-Use Air Showers

Larger models accommodate multiple people, such as double or channel air showers, with dimensions ranging from 2.4m x 1.5m x 2.5m to larger custom configurations.

List of Relevant Specifications and Standards:

1. Air Velocity: 20-25 m/s for optimal particle removal.

2. Filter Efficiency: HEPA/ULPA filters with 99.97% efficiency.

3. Noise Level: ≤ 75 dB.

4. Certification: ISO 14644 and GMP compliance.

Determine the Material of the Air Shower According to the Investment Budge
