Professional Airflow Visualization Studies (AVS) for cleanrooms, biological safety cabinets (BSCs), laminar airflow workstations (LAFWs), isolators, Restricted Access Barrier System (RABS), filling lines, and critical manufacturing environments.
SOKOL GxP Services helps organizations verify airflow performance, demonstrate first air protection, and support contamination control strategies through professionally executed airflow visualization studies. Our studies are designed to meet current regulatory expectations, including updated EU GMP Annex 1 requirements, while delivering defensible, inspection-ready results.
Why Airflow Visualization Matters
Airflow Visualization Studies (AVS), commonly known as smoke studies, is a critical component of contamination control and aseptic processing. AFV studies provide visual evidence that clean air reaches critical process areas without obstruction and that airflow patterns effectively protect products, materials, and processes from contamination.
The updated EU GMP Annex 1 places increased emphasis on understanding airflow behavior, demonstrating first air protection, and maintaining an effective Contamination Control Strategy (CCS). Properly executed AFV studies provide valuable evidence supporting qualification, risk assessments, and regulatory inspections.
Our studies help organizations:
Demonstrate first air protection over critical sites
Generate inspection-ready evidence for regulators and auditors
Identify turbulence, reflux, and airflow disruptions
Assess operator interventions and material movements
Support Contamination Control Strategy (CCS) programs
Meet Annex 1, FDA, and ISO 14644 expectations
Verify unidirectional airflow performance

Advanced AVS Equipment and Video Capabilities
Unlike many service providers, SOKOL GxP owns and operates its own airflow visualization equipment and professional video production systems. This allows us to select the most appropriate tracer technology for each application and maintain complete control over study quality and execution.
Tracer Generation Technologies
We provide multiple tracer generation options to meet the specific requirements of each facility and application:
Glycol-based smoke generators for long-duration airflow visualization studies
Ultrasonic fog generation systems for applications requiring fine-particle visualization
Liquid Nitrogen (LN₂) fog generation systems for highly sensitive and temperature-controlled environments
Naturally buoyant tracer generation systems for accurate visualization of airflow patterns with minimal influence from tracer density effects
This diverse tracer portfolio allows SOKOL GxP to select the most appropriate technology for each application, ensuring meaningful airflow visualization results across cleanrooms, BSCs, LAFWs, isolators, RABS, filling lines, and other critical environments.
