Abstract
A fume hood is provided with seal strips to prevent or inhibit leakage of air through the sash clearance opening at the top of the hood. A front seal is mounted on the rear wall of the auxiliary air chamber and essentially engages the front surface of the sash when the sash is partially or completely raised, and a rear seal is mounted on the front wall of the working chamber and essentially engages the rear surface of the sash when the sash is raised. If desired, either or both of the seals can have a width sufficient to extend all the way across the sash clearance opening when the sash is lowered to seal the sash clearance opening.
