1. Unique sash provides maximum visibility of 37.5" high while
conserving energy by limiting sash travel to 28". Vertical-rising sash
may be raised from a closed to 28" operating height. Exhaust volume and
blower sizing are based on the 28" height. Optional sash stops are
available to limit sash height and reduce energy usage. The Perchloric
Acid Hood has a glass sash specifically used for Perchloric Acid.
2. By-pass airflow design ensures relatively stable face velocities.
3. Large usable interior work depth and interior height of 48" provides
ample working space.

The baffle may be removed for cleaning purposes only.

valves when access through the sides is not available.
