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.
One of the most trustworthy engineering controls in the lab are fume hoods and we are the leading Fume Hood Manufacturers in India. Fume hoods keep the gases, dust, and vapours produced inside the hood contained, protecting lab users. As air enters a fume hood and exits through the laboratory exhaust system, the fumes are removed. We are the best laboratory fume hood supplier in India.
Fume hood is a essential item in a modern Laboratory, Our range of products include laboratory fume hood, double entry fume hood, bench top fume hood, walk in fume hood, fume hood and ductless fume 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
