| The Auxiliary Air Hood conserves energy by introducing
outside air into the hood, reducing the loss of tempered air from
the laboratory.
Uniflow Auxiliary Aur fume hoods are designed to direct and maintain a smooth uniform flow of air into the fume chamber and across the work surface. Aerodynamic airfoil and tapered sash opening assures efficient air flow through fume chamber. |
 |
The Uniflow Auxiliary Air Fume Hood is equipped with a Variflow adjustable baffle with radiused entry edges to reduce turbulence. Factory adjusted for general laboratory use, the Variflow baffle may be adjusted for specific airflow requirements.
The safety glass viewing sash is counterbalanced for effortless precise positioning to provide clear viewing and maximum operator safety.
Diagrams below detail airflow characteristics of the Auxiliary Air Fume Hood design.
The Auxiliary Air Fume Hood is designed to allow supply air to be introduced through a plenum above the sash opening. When the sash is in a closed position, supply air enters the fume chamber through the by-pass opening and below the air foil. When the sash is in an open position, supply air enters the fume chamber through the sash opening.
