1. Aerodynamic Clean-Sweep™ Air Foil has a unique shape that allows air
to sweep the work surface for maximum containment. The Clean-Sweep™
openings create a constant protective barrier from contaminants. Should
the operator inadvertently block the airflow entering the air foil, air
continues to pass under the air foil and through the Clean-Sweep openings.
See Figures 4-1 and 4-3.
2. Containment-Enhancing Upper Sash Foil includes an open air passage
directly atop the sash foil to bleed air into the hood chamber and direct
chemical, powder and particulate materials away from the sash opening.
The radiused sash foil sweeps airflow into the hood with minimal
turbulence. See Figures 4-1 and 4-4.
