The BioChemGARD e3 meets the NSF Standard 49 classification for a Class II Type B2 biosafety cabinet. The BCG exhausts all inflow and downflow air to the atmosphere through an external building exhaust
system directly connected to the top of the cabinet. Room air enters the front access opening of the cabinet at a minimum of 100FPM then enters the front work surface perforation. The cabinet supply blower draws room air in at the top rear of the cabinet and pushes it into the supply plenum and through the HEPA/ULPA supply filter. Most of the filtered down flow air passes through a diffuser, creating a unidirectional vertical flow in the work area, but some of the air is dumped down the back of the viewscreen creating a high velocity air curtain at the front access opening. The filtered down flow air in the work area splits at the work surface. Some of the air enters the rear work area perforation while most of the air enters the front work surface perforation. The air is pulled into the drain pan area, through the exhaust HEPA/ULPA filters, then up the rear exhaust plenums, and exits the cabinet to the facility exhaust system through a 12” exhaust collar at the top of the cabinet.
