UniFlow Auxiliary Air Fume Hoods

The energy saving Auxiliary Air Fume Hood requires zero room air. This is because the auxiliary air supply is equal to the
CFM exhaust of the hood - thus zero room air is required. With sash at an 1/2 open operating position and a face velocityo f
100 fpm, the supply equals the exhaust; which makes up for insufficient room air availability and by not exhausting
expensive existing tempered room air.
