Functionality and Usage
Air showers play a critical role in maintaining the integrity of cleanroom environments by removing contaminants from personnel and materials before they enter sensitive areas. Customizing an air shower ensures that it meets specific operational needs and industry standards, enhancing efficiency and effectiveness.
Air showers are designed for decontaminating both individuals and materials before entry into cleanrooms. This dual functionality ensures that contaminants from clothing, skin, or packages do not compromise cleanroom conditions.
Dimensions
Air showers come in various sizes to accommodate different needs:
| Type | Description |
|---|---|
| Single Person | Suitable for individual entry, ensuring flexibility in small spaces |
| Double Person | Accommodates two individuals simultaneously, enhancing throughput efficiency |
| Multiple Person | Designed for group entries, suitable for high-traffic CleanRooms |
| Cargo Size | Custom sizes for decontaminating large equipment or bulk goods |
Door Types
Single Door
Offers simplicity and ease of use for individual passage
Double Door
Enhances accessibility for multiple entries or exits
Sliding Door
Saves space and provides smooth operation in confined areas
Rolling Door
Ideal for large cargo entries, allowing for expansive access without compromising the seal

Filtration Systems
HEPA (High-Efficiency Particulate Air)
Removes 99.97% of particles sized 0.3 microns or larger, suitable for general cleanroom applications
ULPA (Ultra-Low Penetration Air)
Offers greater efficiency, capturing 99.9995% of particles down to 0.12 microns, ideal for high-sensitivity environments
Airflow Patterns
Single-Direction Blow
Targets specific areas for efficient particle removal
Bi-Directional Blow
Ensures comprehensive decontamination from multiple angles
Top Blow
Directs air downward, clearing contaminants from head to toe thoroughly
Materials
Sandwich Panels: Lightweight and insulative, suitable for modular installations
201 Stainless Steel (SUS): Offers corrosion resistance at a cost-effective price point
304 Stainless Steel (SUS): Provides superior corrosion resistance, ideal for rigorous environments
Coated Steel Panel: Offers a budget-friendly solution with adequate protection against wear
Common Questions and Answers
What size air shower is required for my facility?
Size depends on expected foot traffic and equipment; single, double, multiple, and cargo sizes are available.
What is the difference between HEPA and ULPA filters?
ULPA filters capture smaller particles and provide higher filtration efficiency than HEPA filters.
Why are bi-directional and top airflow important?
They ensure thorough decontamination by addressing all body areas and surface angles.
How often should filters be replaced in an air shower?
Typically every 6-12 months, depending on usage frequency and environmental conditions.
Which material is best for air shower construction?
It depends on environmental conditions and budget—304 SUS offers excellent resistance for demanding environments.
