Operating the Vertical-
Rising Sash


Because of the Protector Perchloric Acid Hood’s
counterbalanced sash mechanism, it will take only a few
pounds of force to move the sash up or down, and you
can operate the sash smoothly with one or two hands
positioned any where along the handle. The vertical-
rising sash may be raised to a maximum 28" operating
height. The airflow requirements should be sized for the
28" operating height; if using sash stops then the airflow
requirements can be reduced by approximately 40% at
18" or approximately 50% at 15".
