Constant air volume principle
the bypass fume hood is an improved variation on the conventional fume hood.
The bypass is located above the sash facce opening and protected by a grille which helps to direct air flow.
The bypass is intended to address the varying face velocities that create air turbulence leading to air spillage.
The bypass limits the increase in face velocity as the sash nears the fully closed position, maintaining a relatively constant volume of exhaust air regardless of sash position.
Laboratory fume hoods minimize chemical exposure to laboratory workers. They are considered the primary means of protection from inhalation of hazardous vapors, mists and particulate matter. It is therefore, important that all pntentiallty harmful chemical work be conducted inside a properly functioning fume hood.
The speed of the air moving through the hood opening is known as face velocity. This laboratory worker guide is intended to help identify fume hood types and outline exposire control practices in relation to the fume hood.
