Pureair” Fume Exhaust Hood ( Constant volume type) is fitted with a movable front sash and an interior baffle. The sash may be fully opened to accommodate apparatus within the fume hood, while baffle directs exhaust air along specific flow pattern within the enclosure. The constant volume type generally operates at constant exhaust volume with the total exhaust air entering the hood through the sash opening. Closing the sash increases the speed of the air through the sash opening, so that high velocities are to be expected with the sash in the near closed positions.

Bypass type Fume Exhaust Hood

Pureair” make Fume Hood (By-Pass Type) are designed in such a manner that closing the front sash causes a re- distribution of air entering the hood through the sash opening eliminating high velocity air streams in the near closed position of the sash. The bypass opening above the sash minimizes fluctuations in face velocity as the sash is raised or lowered. The bypass hood is more desirable for use with fragile apparatus and instrumentation. Since the face velocity does not reach levels which might be detrimental to experimentation
