SERVICE / 05Air Pattern Visualisation
Airflow Direction Test
Visual assessment of airflow paths to reveal turbulence, dead zones and disruption around equipment and work positions.

Why this test matters
Evidence for confident environmental control.
Airflow parallelism and visualisation testing demonstrates the actual movement of air through a unidirectional cleanroom. It shows how equipment, operators and room geometry influence the protective air pattern around critical work locations.
Visible confirmation that air moves through the critical zone as intended.
Typical scope
Defined around the room, risk and required evidence.
This test is most useful after air-velocity, uniformity and room-pressurisation checks have confirmed the underlying HVAC condition.
- Critical process and transfer positions
- Airflow around equipment and operator locations
- Return-air paths and obstruction effects
- At-Rest or Operational simulation as agreed
A disciplined path from measurement to report.
Stage 2
Position the visualisation source at agreed locations
Stage 3
Observe direction, parallelism, turbulence and dead zones
Stage 4
Record representative patterns and issue recommendations
Validation framework
Testing aligned with the operating context.
The final protocol is confirmed against the facility classification, process risk and applicable quality requirements.
- Unidirectional zones
- Critical processing areas
- Post-balancing verification
