Air Shower NAS-203 is a controlled entry system used in cleanrooms to remove dust and particulate contamination from personnel and materials before entry into sterile environments.
It acts as a contamination barrier between non-clean and clean zones.
Air showers are critical because:
Humans and materials carry dust and particles into cleanrooms
Even microscopic contamination can damage product quality
Semiconductor and pharmaceutical processes require ultra-clean environments
Without air showers:
Product defects increase
Sterility can be compromised
Regulatory compliance failures may occur
Air Shower NAS-203 is used for:
Cleanroom entry contamination removal
Personnel decontamination before gowning areas
Material transfer cleaning
Contamination control in sterile environments
Maintaining ISO cleanroom classification standards
Personnel or materials enter chamber
Interlocking doors seal entry/exit points
HEPA-filtered air jets activate at high velocity
Air dislodges particles from surfaces
Contaminants are captured by filtration system
Cleaned subject exits into cleanroom
High-velocity air jets (20–30 m/s)
HEPA filtration system
Automated interlocking doors
Stainless steel cleanroom-grade construction
Adjustable cycle time (10–30 seconds)
Low-turbulence airflow design
Pharmaceutical cleanrooms
Semiconductor fabrication units
Biotechnology laboratories
Healthcare sterile environments
Food processing industries
Research and testing facilities
Use Air Shower NAS-203 when:
Cleanroom contamination must be minimized
Personnel or materials enter sterile environments
ISO 14644 compliance is required
GMP manufacturing standards must be maintained
High cleanliness levels are mandatory
ISO 14644 → Defines acceptable particle limits in cleanroom environments
GMP (Good Manufacturing Practice) → Ensures controlled, hygienic, and repeatable manufacturing processes
1.What is Air Shower NAS-203 used for?
It removes particles from personnel and materials before cleanroom entry.
2.How does an air shower work?
It uses high-velocity HEPA-filtered air to dislodge and remove contaminants.
3.What is air velocity in Air Shower NAS-203 ?
Typically 20–30 m/s.
4.What filtration is used?
HEPA filtration system.
5.Are air showers mandatory?
Not always, but they are widely used in cleanroom contamination control.
6.Can it remove microbes?
It removes particles and may reduce microbial contamination indirectly.
Air Shower NAS-203 is a cleanroom entry contamination control system designed to remove dust, fibers, and other particulate matter from personnel and materials before they enter controlled environments. It uses high-velocity HEPA-filtered air jets to dislodge contaminants, which are then captured by the filtration system. Widely used in pharmaceutical manufacturing, semiconductor fabrication, biotechnology laboratories, healthcare facilities, and food processing plants, NAS-203 helps maintain ISO 14644 cleanroom classifications and supports GMP compliance by minimizing contamination at critical cleanroom entry points.
