An air shower is a cleanroom entry system designed to remove particulate contamination from personnel and materials using high-velocity HEPA-filtered air.
It acts as a pre-entry decontamination system to maintain cleanroom standards.
Air Shower NAS-206 is used to remove contamination before cleanroom entry.
Personnel must enter cleanrooms without carrying contaminants
Materials require surface decontamination
Controlled environments need strict particle control
It ensures compliance with cleanroom standards and reduces contamination risks.
Personnel/material enters enclosed chamber
HEPA-filtered air is released at high velocity
Particles are dislodged from surfaces
Contaminants are captured via return airflow
Clean air is recirculated
Interlocked doors prevent cross-contamination between zones.
Air Shower NAS-206 is used when contamination control is required before cleanroom entry.
Cleanroom contamination must be minimized
ISO 14644 classification must be maintained
GMP-regulated production is followed
Entry control is critical
Pharmaceutical manufacturing
Biotechnology laboratories
Food processing facilities
Hospital sterile environments
Electronics and semiconductor industries
Air Shower vs Airlock
An air shower removes particles; the airlock controls pressure.
Air Shower vs Pass Box
Air shower cleans personnel and materials; the pass box transfers materials only.
HEPA filtration (99.97% @ 0.3 µm)
Air velocity: 20–30 m/s
Multi-directional nozzles
Adjustable cycle time
Door interlocking system
Digital control panel
Air Shower NAS-206 is a cleanroom entry contamination control system used to remove particles from personnel and materials.
It prevents contamination transfer and helps maintain cleanroom standards.
It is used before entering contamination-controlled environments.
No, but it is strongly recommended in regulated industries.
It uses HEPA-filtered high-velocity air to dislodge and remove particles from surfaces.
Pass Boxes – material transfer
Garment Cabinets – apparel storage
Air Handling Units – environmental control
ISO 14644 (Cleanroom Classification)
GMP (Good Manufacturing Practice)
FDA guidelines
Dust, lint, fibers, and airborne particles.
30–60 seconds depending on protocol.
Yes, based on chamber size and configuration.
Typically all 6–12 months or based on usage.
Yes, through controlled airflow and interlocking doors.
Removes particulate contamination before cleanroom entry
Supports ISO 14644 and GMP compliance
Reduces contamination transfer risks
Ensures controlled cleanroom access
Suitable for pharma, biotech, and electronics industries
Choose Air Shower NAS-206 if:
You operate in contamination-sensitive environments
You need controlled cleanroom entry
You require ISO/GMP compliance
You need both personnel and material decontamination
Air Shower NAS-206 is a high-efficiency cleanroom entry contamination control system designed to remove dust, lint, fibers, and airborne particles from personnel and materials before they enter controlled environments. It uses HEPA-filtered air (99.97% efficiency at 0.3 µm) delivered through high-velocity nozzles at 20–30 m/s to dislodge contaminants and capture them through a recirculating filtration system.
