Vanguard
Variable Air Volume Fume Hood
The Variable Air Volume fume hood combined with an HVAC control system is designed to vary the hood’s
exhaust rate to maintain a constant average face velocity throughout the sash travel. In addition the
aerodynamic airfoil located under the sash creates a sweeping air movement at the work surface to reduce
dead-air pockets and air turbulence at the work surface front.
The VAV system has a higher initial cost than the conventional installation due to the complexity of the control
system, however it offers reduced energy consumption for long term savings. These hoods are designed to
be mounted to a 30” deep x 11/4” thick counter top.
