Introduction

An air shower is a critical device installed at the entrance of cleanrooms to remove dust and particles from personnel or materials, ensuring a contamination-free environment. Selecting the right air shower enhances cleanliness and reduces operational costs. This guide explains how to choose the best air shower and key factors to consider.

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.
