  • Airfoil and baffle assemblies that reduce airflow requirements for fume hoods and fume hoods incorporating same
    Patent number: 9056339
    Abstract: A fume hood includes a ventilated chamber having an access opening. A first elongated airfoil assembly is attached to an edge portion of a floor that extends from the opening. A sash is slidably mounted at the access opening and a second elongated airfoil assembly is attached to a lower edge of the sash. The first elongated airfoil assembly includes a plurality of elongated vanes in vertically spaced-apart relationship that define air flow channels. The second airfoil assembly includes a pair of elongated vanes in vertically spaced-apart relationship that define air flow channels that extend into the chamber. A baffle assembly is located in front of a rear wall of the chamber and includes a primary panel having a plurality of vertical air-exit slots adjacent a lower edge, and a buffering panel having a plurality of horizontal air-exit slots adjacent an upper portion.
