Air Shower NAS-205 is a controlled entry contamination removal system used in cleanrooms to eliminate dust and particles from personnel and materials before entry.
It acts as a physical contamination barrier between non-clean and clean environments.
Air showers are essential because:
Humans continuously carry dust, fibers, and particles
Even microscopic contamination can damage sensitive production
Semiconductor and pharmaceutical environments require ultra-clean conditions
Without air showers:
Product rejection rates increase
Batch contamination risk rises
Regulatory compliance failures may occur
Production downtime increases
Air Shower NAS-205 is used for:
Cleanroom entry contamination removal
Personnel decontamination before gowning
Material transfer cleaning
Sterile environment protection
ISO-classified cleanroom compliance support
Personnel or materials enter chamber
Interlocking doors seal entry zone
HEPA-filtered air jets activate
High-speed airflow dislodges particles
Contaminants are captured by return filtration system
Cleaned personnel/material exits into cleanroom
High-velocity HEPA-filtered air jets
Multi-directional nozzle system
Interlocked safety door system
Stainless steel cleanroom-grade construction
Adjustable cycle control (30–60 sec)
Low-turbulence airflow design
Pharmaceutical cleanrooms
Biotechnology laboratories
Healthcare sterile zones
Semiconductor fabrication units
Food processing facilities
Electronics manufacturing plants
Use Air Shower NAS-205 when:
Cleanroom contamination risk is high
Personnel or materials enter sterile environments
ISO 14644 compliance is mandatory
GMP/FDA regulated production is required
Particle-free environment is critical for quality
Choose based on function, not structure
ISO 14644 → Defines maximum airborne particle limits in cleanrooms
GMP → Ensures controlled, repeatable, contamination-free manufacturing
FDA Guidelines → Ensures pharmaceutical safety and regulatory approval
Without compliance, product quality and regulatory approval are at risk.
1.What is Air Shower NAS-205 used for?
It removes particulate contamination before cleanroom entry.
2.How does an air shower work?
It uses HEPA-filtered high-velocity air to dislodge and capture particles.
3.What is air velocity in Air Shower NAS-205?
Typically 20–30 m/s.
4.What filtration is used?
HEPA filtration system.
5.How long is the cycle time?
30–60 seconds depending on protocol.
6.Is it mandatory in cleanrooms?
Not mandatory, but widely used in controlled environments.
7.Can it reduce microbial contamination?
Yes, indirectly by removing particle carriers.
Air Shower NAS-205 is a cleanroom entry contamination control system designed to remove dust, fibers, and airborne particles from personnel and materials before they enter controlled environments. It uses high-velocity HEPA-filtered air jets (20–30 m/s) to dislodge contaminants and capture them through a recirculating filtration system within a 30–60 second cycle.
