To determine the actual face velocity at the sash opening, airflow velocity readings
will need to be taken. This should be done across the sash opening of the
enclosure in accordance with the Industrial Ventilation Manual. (See Appendix E)
The “average face velocity” is achieved by taking readings in two rows across the
enclosure with the readings 6" from the ends and evenly spaced every 12"; the first
row is 3" down from the upper sash foil and the second row is 3" up from the work
surface. A total of eight readings are taken for the 4' Protector Work Station and
then averaged.
