Air Shower NAS-202 is a controlled contamination removal system used at cleanroom entry points. It uses high-velocity filtered air to remove dust and particles from personnel and materials before they enter sterile environments.
It acts as a protective barrier between uncontrolled and controlled environments.
Air showers are essential because:
Humans carry dust, fibers, and particles into cleanrooms
Even microscopic contamination can affect product quality
Semiconductor and pharmaceutical industries require ultra-clean environments
Without air showers:
Product defects increase
Sterility is compromised
Regulatory compliance may fail
Air Shower NAS-202 is used for:
Cleanroom entry decontamination
Personnel particle removal before gowning
Material transfer cleaning
Contamination control in sterile environments
Maintaining ISO cleanroom classification integrity
Personnel or materials enter chamber
Interlocking doors prevent contamination leakage
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
Interlocking automatic 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 & testing facilities
Use Air Shower NAS-202 when:
Cleanroom contamination must be minimized
Personnel or materials enter sterile environments
ISO 14644 compliance is required
GMP-controlled production is mandatory
High cleanliness standards are essential
ISO 14644 → Defines allowable particle limits in cleanrooms
GMP → Ensures controlled, repeatable, and hygienic manufacturing processes
What is Air Shower NAS-202 used for?
It removes particles from personnel and materials before cleanroom entry.
How does an air shower work?
It uses high-velocity HEPA-filtered air to dislodge and capture particles.
What is air velocity in Air Shower NAS-202?
Typically 20–30 m/s.
What filtration is used?
HEPA filtration system.
Are air showers mandatory?
Not always, but they are commonly used in cleanroom entry zones.
Can it remove microbes?
It mainly removes particles but may reduce microbial contamination indirectly.
Air Shower NAS-202 is a cleanroom contamination control system designed to remove dust, fibers, and other particulate contaminants from personnel and materials before they enter controlled environments. It uses high-velocity HEPA-filtered air jets to dislodge particles, which are then captured by the filtration system. Commonly used in pharmaceutical cleanrooms, semiconductor manufacturing, biotechnology laboratories, healthcare facilities, and food processing plants, NAS-202 helps maintain ISO 14644 cleanroom classifications and supports GMP compliance by reducing contamination risks at critical entry points.
