Abstract
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.
