Laminar airflow unit is an area that is controlled the airflow pattern to be laminar, as it is highly likely that with unidirectional airflow could lower the risk of contamination in orderly pattern. Conversely, non-unidirectional airflow pattern could not be controlled, resulting to have high risk of contamination.
Laminar Airflow Unit
The procedure of testing will be the same as individual cleanroom consist of :
– Airflow Velocity and Uniformity Tests
– HEPA Filter Installation Leak Tests
– Airborne Particle Count Cleanliness Classification Tests
– Differential Pressure and Magnehelic Gauge Reading
– Airflow Smoke Pattern Tests
Normally, Laminar cabinet cleanliness class is “A” or class 100
