Laminar Air Flow Qualification for Biosafety Cabinets. Here’s what is required to get the job done right.
This page will give you the answers you need.

Laminar Air Flow Performance Qualification
If you work in a pharmacy, laboratory, or clean room you understand the importance of critical containment equipment like Biosafety Cabinets and Laminar Air Flow Hoods. They are integral to the safety of workers and it’s not enough to just have them … you have to be sure that they are performing properly at all times. It is required as part of USP 797, USP 800, as well as compliance with NSF/ANSI-49 & OSHA.
The products manufactured by DegreeC help you to tackle these requirements and achieve compliance. Plus, our world-class support team is here to walk you through it and make sure that you’re safe 24/7/365. Here are some of the ways we can help:
- Air Velocity Sensors: Critical Areas should have laminar airflow of 90 fpm ± 20%, or 28 m/min ± 20%
- Airflow Monitors, Laminar Air Flow Hoods: During average supply air velocity testing, the average reading must be between 120-130 fpm, or 35-40 m/min.
- Airflow Monitors, Biosafety Cabinets: The calculated average intake air velocity must be between 100-130 fpm or 30-40 m/min
- Smoke Testing: Airflow will be unidirectional. During airflow smoke pattern testing with a smoke wand or fog generator, airflow along the entire perimeter of the work access area will be inward; the smoke will flow downward with no dead spots or reflux within the cabinet; no airflow escape from the cabinet and no billowing over or penetrating the work surface




What is a Laminar Air Flow Qualification Testing?
Simply put, it is periodic testing of Laminar Air Flow Cabinets to ensure that they are performing to spec. The frequency with which Laminar Air Flow Qualification Testing is performed, as well as the number of sample points tested are generally influenced by your application, risk assessment, workflow and workload.
