Most of the HEPA filtered down flow air passes through a diffuser but someof the air is dumped down the back of the viewscreen creating a high velocity air curtain at the front accessopening. The HEPA filtered down flow air in the work area splits at the work surface. Some of the air enters therear work area perforation while the remainder of the air enters the front work surface perforation. The air ispulled through the drain pan area, up the rear and side wall plenums, to the cabinet blower. The air is thenpushed into the positive pressure plenum. At that point most of the air is pushed through the down flow HEPAfilter while the remainder is exhausted out the exhaust HEPA filter and through a perforated filter protector atthe top of the cabinet.[Reference Figure1]EXHAUSTEXHAUST HEPAFILTERPOSITIVE PRESSUREPLENUMDOWN FLOW HEPAFILTERINTAKE(ROOM AIR)= ROOM AIR= CONTAMINATED AIR= HEPA FILTERED AIRWORK AREADRAIN PAN AREAFigure1, Airflow Inside Cabinet1
