Air Shower NAS-200 is a controlled entry contamination removal system used in cleanrooms. It uses high-speed filtered air jets to remove dust and particles from surfaces before entry into sterile environments.
It acts as a critical contamination barrier between uncontrolled and controlled zones.
Air showers are essential because:
Personnel carry dust, fibers, and particles into cleanrooms
Even microscopic contamination can affect product quality
Semiconductor and pharmaceutical processes require ultra-clean conditions
Without air showers:
Product defects increase
Sterility is compromised
Regulatory compliance may fail
Air Shower NAS-200 is used for:
Cleanroom entry decontamination
Personnel particle removal before gowning zones
Material transfer cleaning
Contamination reduction in controlled environments
Maintaining ISO classified cleanroom integrity
Doors interlock to prevent contamination leakage
HEPA-filtered air jets activate at high velocity
Particles are dislodged from surfaces
Contaminants are captured in filtration system
Cleaned subject exits into cleanroom environment
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 manufacturing cleanrooms
Semiconductor fabrication units
Biotechnology laboratories
Healthcare sterile environments
Food processing facilities
Research & testing labs
Use Air Shower NAS-200 when:
Cleanroom entry contamination must be minimized
ISO 14644 cleanroom classification must be maintained
GMP compliance is required
Personnel or materials enter controlled environments
High sterility standards are mandatory
ISO 14644 → Defines acceptable particle limits in cleanrooms
GMP → Ensures safe, controlled, and repeatable manufacturing conditions
1.What is an air shower used for?
It removes dust and particles from personnel or materials before entering cleanrooms.
2.How does Air Shower NAS-200 work?
It uses high-velocity HEPA-filtered air to dislodge and remove particles from surfaces.
3.What is the air velocity?
Typically 20–30 m/s.
4.What filtration is used?
HEPA filters are used to capture particles removed during the cycle.
5.Are air showers necessary?
Yes, they are widely used in cleanrooms to maintain contamination control.
6.Can air showers remove microbes?
They mainly remove particles, but may indirectly reduce microbial contamination.
Air Shower NAS-200 is a cleanroom entry system designed to remove dust, fibers, and other particles 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. Commonly used in pharmaceutical manufacturing, semiconductor facilities, biotechnology laboratories, and healthcare cleanrooms, NAS-200 helps maintain ISO 14644 cleanroom classifications and supports GMP compliance by reducing the risk of contamination.
