Selecting the right air shower is an important step in building a safe, efficient, and compliant cleanroom entry system. A well-designed air shower helps remove loose particles from personnel and materials before entering controlled environments, reducing contamination risk and improving overall cleanroom performance. This guide explains the key factors you should consider when choosing the most suitable air shower for your facility.
Different industries and cleanroom grades require different contamination-control levels. Before choosing an air shower, clarify:
Your cleanroom classification (ISO 5–8 or corresponding GMP class)
Personnel flow (number of operators entering per hour)
Process sensitivity (electronics, pharmaceuticals, food, precision manufacturing, etc.)
High-sensitivity environments typically require:
Higher air velocity
More nozzles
Faster cycle time
Stronger filtration performance
Understanding your application ensures you select an air shower that meets your cleanliness goals.
Air showers come in several configurations based on space, personnel flow, and operational design.
Ideal for small cleanrooms
Compact size, cost-effective
Suitable for low personnel traffic
Higher throughput
Reduced waiting time during peak hours
Designed for high-volume production facilities
Continuous flow
Suitable for electronics, pharmaceuticals, and large factories
For trolleys, carts, raw materials, or equipment
Wider and higher door clearance
Choosing the correct configuration ensures smooth entry flow and prevents bottlenecks.
Air shower doors directly influence efficiency and user experience.
Simple structure
Low maintenance
Suitable for small cleanrooms
Hands-free operation
Improved hygiene
Faster entry and exit
Recommended for pharmaceutical and food production environments
Make sure the doors include interlocking systems to prevent cross-contamination.
Air shower performance depends on air velocity, filtration efficiency, and nozzle layout.
Air Velocity: Typically 20–25 m/s
HEPA Filtration: H13 or H14 efficiency
Nozzle Quantity and Positioning: Ensures full body coverage
Air Circulation System: Stable, high-pressure airflow
These factors determine how effectively the air shower removes dust and particles from clothing surfaces.
Different industries require different materials for durability, hygiene, and corrosion resistance.
Powder-coated steel: Cost-effective, suitable for standard cleanrooms
Stainless Steel 304: Higher corrosion resistance
Stainless Steel 316: Best for pharmaceutical or chemical environments
High-quality construction ensures long-term performance and reduces maintenance costs.
Modern air showers often include intelligent features to improve convenience and monitoring.
Recommended features include:
Touchscreen control panel
Adjustable shower cycle time
HEPA filter replacement alerts
Error alarms and maintenance indicators
Access-control or RFID integration
Energy-saving operation modes
These functions help maintain stable performance and modernize cleanroom management.
Air showers require proper space planning to ensure smooth installation and safe operation.
Consider:
Entrance and exit direction
Door swing or sliding clearance
Ceiling height and equipment width
Power supply and electrical requirements
Integration with cleanroom airflow systems
Good planning avoids unnecessary modifications during installation.
Always choose air showers that meet relevant standards, such as:
ISO cleanroom guidelines
GMP requirements
Local safety and electrical regulations
Compliance ensures safety, reliability, and successful cleanroom validation.
Choosing the right air shower involves understanding your cleanroom needs, evaluating airflow performance, selecting durable materials, and ensuring compliance with industry standards. A well-selected air shower improves personnel decontamination efficiency, reduces contamination risks, and supports stable cleanroom operations.
