Auxiliary Air Fume Hood

Auxiliary Air Fume Hood

Auxiliary Air Fume Hoods are constant volume hoods designed for use when it is not feasible to introduce the required makeup air through the room ventilation system. Up to 70% of the exhaust volume can be supplied through an auxiliary chamber mounted above the hood. The auxiliary air is typically introduced exterior to the fume hood face and enters the fume hood through the face with the sash(es) open. With the sash(es) closed, the air bypass provides for an alternate route for air to enter the hood.
