Balanced Air Fume Hood

Widely used in hospitals, industrial labs and research facilities, the Balanced Air Fume Hood controls the
air velocity through the hood. With conventional hoods, face velocity becomes excessive when the sash is
at a lower position, disturbing the work being conducted inside the hood. This inconvenience is reduced
with the balanced air fume hood because it maintains a more constant face velocity. When the sash is
lowered, air is fed through the louvered top section as well as through the aerodynamic airfoil located under
the sash creating a sweeping air movement at the work surface to reduce dead-air pockets and air
turbulence at the work surface front.

These upper and lower bypasses allow the hood to be effectively purged while the work inside remains undisturbed.

These hoods are designed to be mounted to a 30” deep 11/4” thick counter top.
