Abstract
A fume hood for venting fumes comprising a cabinet, a venting system, and a split sash. The cabinet defines a working area. The cabinet has a front face which comprises an opening for providing access to the working area. The venting system is connected to the cabinet and vents fumes that collect in the working area of the cabinet. A split sash is movably secured to the front face of the cabinet for selectively opening and closing the opening to the working area of the cabinet. The split sash comprises at least two panels that move in unison between closed and open positions. Further, the fume hood comprises a bypass having an opening formed in the face of the cabinet for controlling the face velocity of the cabinet and means for selectively adjusting the size of the bypass opening.
