Abstract
A negative pressure containment system is configured to run in lateral air flow mode or enhanced controlled environment mode, depending on the operator's needs. A diverter assembly facilitates switching between modes by directing air into alternative air chases. In the enhanced controlled environment mode there are two concurrent air paths that eventually converge, with one path being a bypass flow that creates negative pressure in the main chamber and another path being compressed air that feeds the main chamber. In this mode it is possible to precisely control the chamber environment.
