Cabinet Interior- 16 gauge corrosion resistant stainless-Steel sheet, type 304, no. 4 finish, side walls and 22” deep work surface. Provide high velocity return air slots in the side walls and leading edges of the work surface to protect against backwash of dirty air entering the work area when items are placed within the air stream on the work surface. Provide welded, gasketed and/or sealed joints for cabinet components to achieve a seal when completely assembled. Unit work surface shall feature 5/8” Spill Guard at rear to prevent accidental spillage into Hepa filter area. Provide drain pan to capture spilled liquids. Drain pan shall have easy access for routine cleaning.

B. Controls – Unit shall have light and blower switches and analog pressure gauge for visual motor failure indicator.

C. Illumination: Cabinet shall have top mounted fluorescent lighting fixture with solid state ballasts producing an average of 150 foot candles at work surface. Design shall accommodate energy efficient bulbs and provide balanced lighting at the work surface.
