• Selection Guide — SASH TYPE — VERTICAL SASH

    Vertical sash hoods provide the best horizontal and vertical access to the hood interior but they also have the highest exhaust requirements. The exhaust requirements can be reduced by using gravity sash stops, although, this restricts the vertical access into the work area. Split sash hoods can be used where needed for two work areas.

    Selection Guide — SASH TYPE — HORIZONTAL SASH

    Horizontal sash hoods provide good access into the hood vertically and allow for lower exhaust requirements. These sashes do restrict the access across the hood for loading of equipment and apparatus. This limitation becomes less significant in larger hoods.

    Selection Guide — SASH TYPE — COMBINATION SASH

    Combination vertical rising/horizontal sash hoods, as the name implies, provide the benefits of both the vertical and horizontal sash hoods. For normal operation the sash can be partially raised vertically, or the horizontal panels can be used. The sash can be fully opened vertically for loading equipment into the hood.

    Selection Guide — SASH TYPE — VERTICAL SASH

    Telescoping combination sash used on Kewaunee's Dynamic Barrier fume hood uses an interlocking twin sash mechanism that combines a restricted combination vertical rising/horizontal sash and small vertical rising sash to allow a very large 37" vertical opening. This sash facilitates set-ups while keeping the work opening small.
