A biosafety cabinet including a plenum and a divider positioned in the plenum. The divider divides the plenum into a supply section and an exhaust section. A blower is positioned adjacent the plenum and in fluid communication with the plenum. The blower is configured to simultaneously supply air to both the supply section and the exhaust section of the plenum. An exhaust filter is positioned between the exhaust section and an exhaust outlet. The air supplied to the exhaust section from the blower passes through the exhaust filter. A supply filter is positioned between the supply section and a work area. The air supplied to the supply section from the blower passes through the supply filter. An adjuster may be coupled to the divider to adjust a position of the divider in the plenum.

Biosafety cabinet with divided plenum

The biosafety cabinet has a frame, which defines an enclosed work area and a front access opening, and a work surface along the bottom of the work area. One or more intake openings are positioned along the front access opening adjacent the work surface, a recirculation duct is in fluid flow communication with the intake holes, a supply filter is in fluid flow communication with the recirculation duct, and a supply blower is positioned upstream from the supply filter in fluid flow communication with the recirculation duct. One or more exhaust openings extend along the work surface, wherein at least one exhaust opening is positioned adjacent the front access opening rearward of the intake holes. The exhaust openings are in fluid flow communication with an exhaust duct, an exhaust filter, and an integral exhaust blower.
