Laminar airflow devices

Conventional airflow (also known as turbulent, or non-unidirectional airflow) incorporates HEPA filters, located in-duct, or as room terminal filtration modules (TPMs Fig. 5). Often confused with LAP, conventional airflow does not meet that definition because it allows multiple-pass circulating characteristics or a non-parallel airflow direction, or both. This type of airflow is incapable of producing first air, and is normally used as secondary or buffer filtration in treating a processing or compounding space that contains laminar airflow devices (LAFDs) to maintain primary critical work surface conditions, or in treating other... 

An alternative to an ISO Class 5 LAFW (Laminar Airflow Work Area) device in an ISO Class 8 clean room. The physical facility does not need to be located in a Class 8 area. Gowning still includes hair covers, shoe covers, lab coats, and facemasks. 

Where product is exposed at transitions or packing operations use containment devices such as gloveboxes provide airflow control (laminar flow booths) or as a last resort use the room as containment and provide suitable personal protective equipment for the operators...
