Air showers leverage a three-pronged approach to maximize purification:
Using Directed Forced Airflow
The turbulent high-speed air currents dislodge particles from clothing, shoes, equipment and exposed skin by simple but powerful air velocity.
Utilizing HEPA or ULPA Filtration
Air recirculated in the enclosure goes through HEPA or ULPA filters trapping particles down to 0.12 microns or 0.01 microns respectively.
Providing A Physical Barrier
The air shower structure provides a physical segregation between clean and dirty areas, limiting cross-contamination. Interlocked doors prevent both from opening at once.
