Understanding the Specifications of Air Showers: Key Features and Benefits



Air showers are specialized entry systems used in cleanrooms and other controlled environments to remove contaminants from personnel or equipment before they enter a sensitive area. These systems are critical in industries where maintaining a contamination-free environment is paramount, such as pharmaceuticals, biotechnology, semiconductor manufacturing, and aerospace. Below, we delve into the key specifications of air showers, highlighting the features that make them indispensable in maintaining stringent cleanliness standards.

1. Airflow Velocity and Volume

  • High-velocity Air Jets: Air showers are equipped with high-velocity air jets that blow air at speeds ranging from 20 to 30 meters per second (m/s). This powerful airflow is essential for dislodging particles from clothing and surfaces.
  • Air Volume: The volume of air circulated within the air shower is typically between 1,500 to 3,000 cubic meters per hour (m³/h), ensuring thorough cleaning. The air volume may vary depending on the size of the air shower and the number of nozzles used.

2. Filtration System

  • HEPA Filters: Air showers are fitted with High-Efficiency Particulate Air (HEPA) filters, which can capture 99.97% of particles as small as 0.3 microns. These filters ensure that only clean, contaminant-free air is circulated within the air shower.
  • Optional ULPA Filters: For environments requiring even stricter cleanliness standards, Ultra-Low Penetration Air (ULPA) filters can be installed. These filters capture 99.999% of particles as small as 0.12 microns.

3. Nozzle Configuration

  • Adjustable Nozzles: Air showers typically feature multiple nozzles, often arranged in a strategic pattern to ensure complete coverage of the person or object being decontaminated. The nozzles are adjustable, allowing them to target specific areas more effectively.
  • Multi-directional Airflow: The nozzles are designed to provide air jets from various angles—top, sides, and bottom—ensuring that all surfaces are thoroughly cleaned.

4. Cycle Time

  • Customizable Cycle Duration: The decontamination cycle time can be adjusted based on the level of cleanliness required. Standard cycle times range from 10 to 60 seconds, depending on the application and the level of contamination expected.
  • Automatic Operation: The air shower cycle is initiated automatically when the user enters the chamber, with sensors detecting the presence of personnel or equipment.

5. Construction and Materials

  • Durable Construction: Air showers are typically constructed from robust materials like stainless steel or powder-coated steel, ensuring durability and resistance to corrosion.
  • Seamless Design: The interior surfaces of the air shower are often designed to be smooth and seamless to prevent particle accumulation and to facilitate easy cleaning.

6. Control Systems

  • Programmable Logic Controller (PLC): Many air showers are equipped with a PLC system that allows for precise control over operation parameters, including air velocity, cycle time, and filter status monitoring.
  • Touchscreen Interface: Some advanced air showers feature a user-friendly touchscreen interface for easy programming and monitoring of the system’s performance.
  • Emergency Stop Button: For safety, air showers are equipped with an emergency stop button that allows users to immediately halt the operation if needed.

7. Interlocking Doors

  • Controlled Entry and Exit: Air showers are designed with interlocking doors, which ensure that the entry and exit doors cannot be opened simultaneously. This prevents contaminants from entering the cleanroom during the air shower cycle.
  • Automatic Door Operation: The doors are usually automated, with sensors controlling their opening and closing, further reducing the risk of contamination.

8. Lighting and Visibility

  • Integrated Lighting: Air showers are equipped with bright, energy-efficient LED lighting, ensuring that users can easily see within the chamber during operation.
  • Observation Windows: Clear observation windows allow for monitoring from outside the air shower, providing visibility into the decontamination process.

9. Noise Levels

  • Low-noise Operation: Despite the high air velocity, modern air showers are designed to operate with minimal noise, typically in the range of 60-75 dB, ensuring a comfortable environment for users.

10. Size and Capacity

  • Standard and Custom Sizes: Air showers come in various sizes to accommodate different needs. They can be designed for single or multiple users, with custom sizes available to fit specific space constraints or operational requirements.
  • Personnel and Equipment Models: While some air showers are designed specifically for personnel, others are built to accommodate trolleys, carts, or even large machinery, depending on the cleanroom’s requirements.
