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.
