Airfoil Perchloric

This Fume Hood is specifically designed for the use of perchloric acid. A coved stainless steel liner with integral work surface, an internal water wash down system and water collection trough provide for detailed cleaning of the Hood interior. In addition, the interior baffles are also removable for cleaning to prevent the dangerous build-up of perchlorates. The Perchloric Acid Fume Hood has an internal bypass located above the sash. The bypass operates automatically, opening when the sash is closed and closing as the sash is raised. The bypass provides for a relatively constant face velocity at any sash position.

The sash frame and lower airfoil are constructed of type 316 stainless steel. The interior liner, work surface and baffles are also constructed of type 316 stainless steel. A wash down spray bar is located behind the upper baffle for continuous cleaning behind the baffles. A full width trough is located below the lower baffle to collect the wash down water from both the Hood and ductwork.
