A stainless steel air shower is a purification device that uses high-speed clean airflow to remove contaminants from surfaces. Its operation involves the following stages:

Sensor Activation

Infrared or pressure sensors detect entry and activate the blower automatically.

Manual control options are available for specialized needs.

HEPA Filtration

Built-in HEPA filters (or ULPA filters) purify incoming air, capturing particles ≥0.3μm with 99.99% efficiency.

Pre-filters trap larger particles to extend HEPA lifespan.

High-Velocity Air Jet

Nozzles (mounted on walls/ceiling) eject clean air at 18-25m/s, dislodging dust from clothing or materials.

Adjustable blow time (typically 10-30 seconds) ensures thorough decontamination.

Air Recirculation/Exhaust

Contaminated air is collected via floor vents and recirculated through filters for energy efficiency.

Some models feature exhaust systems for highly polluted environments.

Key Components & Material Advantages

Stainless Steel Body: 304 or 316L steel offers corrosion resistance and easy cleaning, complying with GMP standards.

Blower System: Low-noise centrifugal fans provide stable airflow and long service life.

Control Panel: Programmable PLC settings for timing, temperature, etc.

Safety Features: Emergency stop buttons and interlock doors (preventing airflow leakage).

Conclusion

Stainless steel air showers ensure clean environments through advanced airflow design and filtration. As industry standards rise, their adoption will continue growing.
