It is a dynamic barrier of HEPA-filtered unidirectional air flow to move particles away from the filling/closing area. Laminar Air Flow Operation (LAF-Operation), HEPA is an acronym for High Efficiency Particulate Air or High Efficiency Particulate Arrestance. Laminar flow is defined as airflow in which the entire body of air within a designated space is uniform in both velocity and direction. Difference between Laminar Air Flow and Reverse Laminar Air Flow Various aspects of protection offered are dependent on the sample, the environment, and the user as well. Though a boundary layer of air sticks to a wing, the air overtop should be moving quickly and smoothly to reduce friction drag. The air system should be provided with appropriate filters such as HEPA for grades A, B, and C. (b) The guidance given for the maximum permitted number of particles in the at rest condition corresponds approximately to the US Federal Standard 209E and the ISO classifications as follows: grades A and B correspond with class 100, M 3.5, ISO 5; grade C with class 10000, M 5.5, ISO 7 and grade D with class 100000, M 6.5, ISO 8.
