Abstract
A fume hood having top and rear baffle systems fixedly secured within a housing of the fume hood to provide a passage for lighter than air fumes along the top baffle and a passage for heavier than air fumes along the rear baffle. A movable damper selectively connects these passages with an exhaust of the fume hood, and this movable damper is remotely controlled from outside the fume hood adjacent the work area of the fume hood. An operator can control fume flow within the hood while the work area is closed by a sash.
