1. Determine Cleanliness Requirements

Different industries have varying standards:
Electronics Manufacturing: Typically requires ISO Class 5 (Class 100) or higher
Pharmaceuticals: May need ISO Class 4 (Class 10)
Food Industry: Usually ISO Class 7 (Class 10,000) suffices
Choose filtration efficiency (e.g., HEPA H13/H14 or ULPA U15) based on industry needs.

2. Select the Right Type

Main types of air showers:
Single/Double-Person Air Showers: Suitable for low-traffic areas
Material Air Showers: Designed for goods and equipment
Automatic Sensor Air Showers: Improve efficiency
Stainless Steel Air Showers: Ideal for humid environments

3. Airflow & Nozzle Design

Air Velocity: 20-25 m/s effectively removes particles
Nozzle Arrangement: Uniform coverage for full-body cleaning
Adjustable Nozzles: Accommodate different user heights

4. Material & Durability

Stainless Steel (304/316): Resists corrosion

Cold-Rolled Steel + Powder Coating: Standard option
Explosion-Proof Design: For hazardous environments

5. Energy Efficiency & Smart Features

Variable Frequency Control: Reduces power consumption
Automatic Doors: Minimize air leakage
Touchscreen Panel: Easy parameter adjustment

6. Choosing a Supplier

Certifications: Ensure compliance with ISO 14644, GMP
After-Sales Service: Includes maintenance & filter replacement
Customer Reviews: Check industry case studies

Conclusion

The best air shower depends on cleanliness standards, type, airflow, material, and supplier reliability. Investing in a high-quality air shower improves cleanliness and long-term cost efficiency.
