Essential contamination control for cleanroom environments
what is an air shower?
An air shower is a specialized enclosure used to prevent contamination in cleanrooms and other controlled environments. It works by using high-velocity jets of hepa- or ULPA-filtered air to remove dust, lint, and other particulate matters from personnel or equipment entering or exiting the clean area.
Key Features
- HEPA/ULPA filtered air jets
- Electronic interlock doors
- Automated operation
- Customizable configurations
- Stainless steel construction options
Classification of Air Showers
| Type | Description | Applications |
|---|---|---|
| Single Air Shower | For small-scale clean demand, single person use | Small labs, limited access areas |
| Multi-person Air Shower | Accommodates multiple people simultaneously | High traffic CleanRooms |
| Stainless steel air shower | Corrosion resistant, easy to clean | High cleanliness, sanitary environments |
| Goods Air Shower | Designed for equipment and materials | Material transfer areas |
| Customized Air Shower | Tailor-made for specific requirements | Specialized industrial applications |
Working Principle
- Air filtration through HEPA/ULPA filters
- High-speed air circulation
- Directed nozzle spraying
- Controlled door interlock system
- Automated cycle completion
Maintenance Checklist
- Regular interior cleaning
- Filter replacement (HEPA/ULPA)
- Fan and electrical system inspection

Key Advantages
Contamination Control
Effective removal of surface particles from personnel or objects entering clean areas.
Cost Efficiency
Reduces operational costs by minimizing contamination load on main Cleanroom filters.
Process Efficiency
Automated cycles enhance throughput and maintain consistent cleanliness standards.
Frequently Asked Questions
How long does a typical air shower cycle last?
The duration varies but typically ranges from 10-60 seconds depending on the cleanliness requirements and specific protocols of the facility.
What industries commonly use air showers?
Industries such as pharmaceuticals, biotechnology, Semiconductor manufacturing, and aerospace employ air showers to maintain stringent contamination standards.
How are air showers maintained?
Regular maintenance involves changing filters, checking air nozzles for clogging, and ensuring door interlocks function correctly.
Conclusion
Air showers play an important role in modern cleanroom environments. Their effective dust removal and isolation functions can significantly improve air cleanliness and protect products and production processes. Choosing the right type of air shower, and operating and maintaining it according to specifications, ensures the efficient operation of the cleanroom and provides the necessary environmental safeguards for related industries.
