Cross Contamination Barriers

Preventing Particle Transfer at Cleanroom Entry & Exit Points

Maintaining a contamination-free environment is essential in cleanrooms and controlled manufacturing zones. Dyna’s Cross Contamination Barriers are purpose-built systems that act as protective checkpoints at the entry and exit of cleanrooms to prevent particulate transfer from people, garments, and materials. These barriers include a range of solutions—from air showers, water and mist showers, to pass boxes and de-dusting tunnels—each designed to minimize the risk of airborne and surface contaminants entering sterile zones.

These systems are widely used across pharmaceuticals, biotech, electronics, food processing, healthcare, and aerospace industries where process integrity and product sterility are non-negotiable. Dyna’s contamination control equipment ensures controlled movement of personnel and material, maintaining compliance with ISO 14644, GMP, and FDA regulations.

Key Features:

Effective Particle Removal – Removes loose dust and contaminants off the personnel and or products before cleanroom entry.
Multiple Configurations – Available for both man and material movement.
Custom Air & Water Jets – High-velocity adjustable nozzles ensure thorough decontamination.
Stainless Steel Construction – GMP-grade, corrosion-resistant, and cleanroom-friendly.
Programmable Operation – Sensors, timers, and interlocks for safe, efficient functioning.

Applications:

Pharmaceutical Cleanrooms – Man and material decontamination before gowning and production.
Biotech & Life Sciences – Prevents cross-contamination between labs and process zones.
Automobiles – Prevents cross-contamination or dust ingress while personnel transit in or out of paint shops, surface coating plants, etc.
Chemical & Nutraceutical Units – Safe transfer between controlled and uncontrolled environments.
Hospitals & Isolation Wards – Infection control in sterile corridors and wards.
Semiconductor & Electronics – Dust prevention in static-sensitive areas.
Food & Beverage Plants – Ensures hygiene compliance before entering processing areas.

Frequently Asked Questions (FAQs)

What is a cross contamination barrier in cleanroom design?

It’s a physical or engineered system like air showers or pass boxes used to prevent particles or biological contaminants from crossing clean and unclean areas.

Can Dyna’s contamination control systems be customized?

Yes, all systems are modular and customizable in size, nozzle configuration, control logic, and filtration levels.

What standards do these products comply with?

Dyna’s barriers comply with ISO 14644, GMP, FDA, and cleanroom safety standards.

What’s the difference between air shower and mist shower?

Air showers remove dry dust using high-speed air jets; mist showers neutralize particles using fine liquid mist.
