The Air By-Pass fume Hood automatically redistributes air above and below the sash, minimizing fluctuations in face velocity as the sash is raised or lowered. Ideal for lab work requiring delicate procedures. Uniflow Air By-Pass 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 Air By-Pass Fume Hood is equipped with a Variflow adjustable baffle with radius 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 Air By-Pass Fume Hood design.
